    is bitdefender for whoever is using it.

    Bitdefender update went out this morning and killed something.

    did a restore to earlier date on one system. worked fine again.

    once the update hit. broke.
    Oh joy. I'll try to do a system restore.

    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
