I followed http://msdn.microsoft.com/en-us/library/5hs4b7a6.aspx to diasble Just-In-Time-Debugging.
I deleted the following registry key in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger
Is it possible to undo it? If yes, then how?
Because now when I try to install a new Windows Service, it opens a Set Service Login dialog box and asks for a user name and password. I can't get any of the combinations to work!
