I have a Windows 7 laptop. In the past week, I had 3 major startup problems. First one was with the message "The user profile service failed the logon. User profile could not be loaded." I could only resolve it with System Restore. Second, Windows created and loaded a default profile due to a problem with the default (usual) one. This seemed to be resolved with a reboot. Third time problem was the same as the first one; System Restore failed all 3 times I tried. I had to manually change profile settings in the registry through safe mode to seemingly resolve the issue.
I thought it was related to some Windows updates and hardware/memory failure, but both were checked and turned up nothing. I tried malware scans with MBAM, SAS and MSSE and they also turned up nothing.
I checked the Event Logs and I found 2 relevant errors that may be of help:
"Windows was unable to load the registry. This problem is often caused by insufficient memory or insufficient security rights. DETAIL - The process cannot access the file because it is being used by another process. for C:\Users\HI\ntuser.dat"
"Windows was unable to load the registry. This problem is often caused by insufficient memory or insufficient security rights. DETAIL - Access is denied. for C:\Users\TEMP.HI-PC\ntuser.dat"
Any help is appreciated.
