Hi Folks,
First of all, many many thanks for the fast and decent support here !!!
Let me overview:
Do you have an old system image, maybe safely on an external?.
We should all have one.
Unfortunatly not :-/
If not try this In an administrator account type cmd in search
click on the cmd
in cmd type sfc /scannow. That may correct the problem
I've got to try that
If not
Put your windows DVD in drive
Select (upgrade)It is now a repair install
That should work.
Yes, I was planning that also.

What protection apps do you have on this machine ? ?
Have you ran the scans ? ?
The problem is not related to other programs.
I have the beta on 3 computers running (some 32-b, some 64b) and it seems that the essential update always gives the problem.
I could roll back (system restore) to a previous state on the other computer, but my personal computer only gives a rollback to the essential update from 2 days ago, so the problem stays.
Now, I could not find a way to undo the update... (uninstalling updates does not work, I think because this is an essential update?)
I was planning to reinstall W7, but offcourse that's a huge work.
Anyway, In august I'll need to buy an official version, because the beta is ending.
But untill then I hope I can cure this
Thx !!!
