The problem appears to be in the registry - so the easiest fix is going to be a System Restore back to before the problem started, since the number of errors makes manual repair unlikely.

Do you know when the problem started?
When was the last Windows Update installed? - ignore MSE or Windows Defender updates

...and actually, you were supposed to go back to Vistax64 to post your results

Hello,
Thanks NoelDP for the information and help, the problem started after Vista updated to SP2 from the Windows Update utility, that was back in Jan , the furthest system restore point I have is beginning of march.

So I guess my only option is to reinstall Vista.

Thanks again and have a great day,

Note: I only noticed the number of errors when you pointed them out only, I giggled

You may be able to get around it by uninstalling SP2 (if the install completed), then doing a repair install.
