Windows was unable to load the registry.

[apache1048]

I have been having performance issues. I believed this was Disc related and I have replaced the disk and used Seagate DiscWizard to clone the disk from the old one to the new one.

I have now started to troubleshoot further and found the following messages in the event viewer.

"Windows was unable to load the registry. This problem is often caused by insufficient memory or insufficient security rights.

DETAIL - The configuration registry database is corrupt.
for C:\Users\Ian\AppData\Local\Microsoft\Windows\\UsrClass.dat"

Looking online it suggests running sfc /scannow which I did and got a log full of messages like

00000569@2015/3/19:14:24:17.867 Sysprep Warning: Corruption detected. Marking Sysprep Corrupt. All Sysprep Commands will be ignored

0000056a@2015/3/19:14:24:17.868 Sysprep Warning: Corruption detected. Sysprep Commands will be ignored

Checking in c:\windows\system32\sysprep.exe says it is not recognized as an internal or external command, operable program or bach file.

Should I replace sysprep.exe at this point and run sfc /scannow again?

Actually the info was incorrect. Sysprep will run (I was at the wrong directory level) so it looks like the file is valid but I do not know how to correct the errors. Is this the correct forum? Thanks....

I would advise reinstalling Windows onto the new drive.

If problems existed with the old one, it is likely that corruption may have occurred during the cloning process.
