creating new profile for existing user on Vista

Every now and then you want to create a new profile in Vista if the original has become corrupt or you feel it has become problematic. In XP, you just had to rename the folder with the user's name in c:\documents and settings.

With Vista, you also need to alter a registry record. You'll need to alter one of the S-15 entries from here:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

One of the folders there will be for the user profile in question. You need to reboot after making the registry changes.
