Repairing Corrupt Windows Profile

What the problem is: the user profile service failed the logon and give you an error when attempting to login to windows.

What is causing said problem: Windows updates sometimes will not install correctly and thus making the user profile corrupt and inaccessible or a malicious piece of software has corrupted your user profile.

How to fix a Corrupt Windows Profile:

1. Start the PC in Safe Mode and open the default account (most likely administrator)
2. Open up the run command and type in “regedit” and then hit ok
3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

There is one line for each profile. If a profile is bad:

• Add the suffex “_new” followed by removing “.bak” from the simliar entry above

Make any necessary changes, close Regedit and try to log in as that user.
