Found a fix: Replace user32.dll

I was in Windows 7 hell for the past 3+ hours. Flashing windows screen, no login prompt unless in safe mode. Event log said logonui.exe was having a problem with a call from user32.dll. However the Startup repair and registry Repair utilities failed to find any problems. Found the fix: boot from the Windows 7 recovery disc, go to command prompt and replace the user32.dll file on the computer. Reboot and voila! Everything works again!

(and for the record, I use BitDefender too!)

Lucky me I always have system restores fail on me and not change a thing. Now what, bitdefender?

Work around

We found a temp fix. In BitDefender, if you exclude both:
C:\Windows\system32\LogonUI.exe as a process
C:\Windows\system32\USER32.dll as a file

When the policy updates it should be fixed.

After restarting user computers, they no longer have the problem.

Not really a fix for us because we are looking at a lot of affected systems right now spread over a wide area (multiple locations).

Sadly I don't have a windows 7 recovery disk. Is there such a thing as a downloadable version of it? The dll I mean
