Solve Messenger forgetting your username and password with Make Messenger Remember
Recently there has been an upsurge of problems regarding Windows Live Messenger “forgetting” Windows Live IDs after a Windows restart. Although there are some known policies in Windows which can cause this to occur, after many hours of testing and research, the latest culprit appears to be the Yahoo Toolbar.
Uninstalling the toolbar will not address the problem as its installer causes damage to your Windows user profile’s registry. To correct all possible causes of this problem, I have created Make Messenger Remember.
How to use
Just download the zip for Make Messenger Remember and run the executable contained inside. Note: Make Messenger Remember will automatically restart Windows after completing its work, so be sure to close and save any data prior to beginning the process.
Choose the Fix button for Make Messenger Remember to make the necessary fixes and restart Windows. After Windows starts again, start Messenger if its not set to automatically do so already, and verify that your Live ID and/or password have returned. In some cases you may have to sign in manually at least more one time.

Special thanks to MersauX, ilyaz and FYu for both testing and providing me the necessary data to create a fix to this problem.
