How To Enable Polygamy In Windows Live Messenger

Many of you will have several WLIDs, and want to sign into Messenger with more than one of them. Until now you had to seek refuge in a patch or add-on to be able to do so. Not anymore! Microsoft’s John Weisenfeld just shared a little trick with me to enable this, which I’m going to share with you.

The trick involves registry editing, so please follow these steps very carefully:

1. Start regedit (admin)
2. Navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Live
3. Right click Messenger and create a new DWORD called MultipleInstances

6. Close regedit

All done! Now you can launch Windows Live Messenger as many times as you want, and sign in with as many WLIDs you want, on one computer. Just don’t try to sign in with the same WLID more than once on one computer or it will throw error 80071392 at you!
