Windows 7, Windowvs Live Messenger Stopped working

If you cannot even start Messenger without getting the “Stopped working” message box try to reset the settings in regedit:


Delete the value of the keys:

  • AppCompatCanary
  • AppSettings

This should make messenger reset the values and start up normally.


Microsoft suggests to do this as well:


Delete key UTL type REG_SZ with your email in: HKEY_CURRENT_USER\Software\Microsoft\MSNMessenger\PerPassportSettings\<Hash Number>

After sign in remember to change your display image.
