Run multiple instances of your favorite Instant Messenger

Whether you use the Internet at home for entertainment or at work, you probably use some kind of instant messaging service to chat either with your buddies or your colleagues at work. Instant messengers like GoogleTalk or Yahoo Messenger by default allow only one instance of the application to be run, which means that you can login with only one user name at one time from one computer. But most of these application allow more than one instances of the application to be run, either by a registry edit or simply by changing a setting of the program. The following is a compilation of all the tricks for popular instant messaging clients that allow one to login with different user names from the same computer.


1. Navigate to the folder where you have installed GoogleTalk. Right-click the executable file (googletalk.exe) and click Create Shortcut.
2. Now Right-click on the newly created shortcut and click Properties
3. In the target box add /nomutex at the end like this

"c:\program files\google\google talk\googletalk.exe" /nomutex

4. Click OK and you are done.

Yahoo Messenger

Open Notepad, paste the following code and save it with the extension .reg

Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\yahoo\pager\Test]

Now run the file to merger it with registry. You can now run multiple instances of Yahoo Messenger. If you are not happy and want to revert back to the original settings, then create another .reg file with the following code and run it.

Windows Registry Editor Version 5.00

If you don’t want to mess with regsitry then you can use Y! Multi Messenger. Y! Multi Messenger is a free and useful utility that allows you to run multiple instances of Yahoo! Messenger instead of only keeping one open.
