Other than Windows Live (MSN) Messenger and Yahoo! Messenger, users of Google Talk (GTalk) can also let Google Talk go to polygamy, that’s running multiple instances of Google Talk and login to multiple Google accounts on Google Talk. The polygamy trick can be done without any crack, patch or hack, with just a simple command line parameter or switch (/nomutex) appended to the Google Talk shortcut.
Ability to polygamy running multiple Google Talk is useful if users have multiple Google Talk accounts (or Google or Gmail accounts that used to login to GTalk) or multiple profiles or personalities, and don’t want to log on and off from one account to another account every time when want to switch, or want to log in to all accounts at the same time on the same computer.
You can add the /nomutex switch or parameter to existing Google Talk shortcut, or create a new shortcut with the /nomutex command line parameter.
To edit existing Google Talk shortcut:
“c:/program files/google/google talk/googletalk.exe” /nomutex
To create a new shortcut for Google Talk:
“c:/program files/google/google talk/googletalk.exe” /nomutex
If you have hex editor, you can act like a hacker and modify the bits in Google Talk program so that it will always allow multiple instances of GTalk to be launched whether the /nomutex switch is specified or not.
Launch hex editor and open googletalk.exe, then search for the following patterns in the hex editor:
004536FD . 3BC6 CMP EAX,ESI
004536FF . 75 05 JNZ SHORT googleta.00453706
Modify the string to look like the following:
004536FD . 8BC1 MOV EAX,ECX
004536FF . EB 05 JMP SHORT googleta.00453706
