Win 7 Msg Privileges after PSU failure. Tweaking doesn't work

[Larbo]

Hi,

I had a PSU failure on my Win 7 Desktop and it made WU inoperative, can't open Word files (missing access privileges) and killed shortcuts. I took a look at Tweaking and it couldn't get past the first Start Up Check test indicating missing files:

Are these issues that Tweaking can fix??

Boggin, in case you forgot, you helped me about 6mos ago under weird but similar circumstances. Tried to do a Windows disc install repair but kept failing. I finally got it to complete and it has been great since.... until.....

[Boggin]

Can you boot up with your install disk, select Repair your computer and navigate to the Command Prompt and enter these cmds -

bcdedit |find "osdevice" then using your partition letter instead of the X I have exampled, enter this cmd -

For clarity that is a Pipe symbol before find and is the upper case of \

sfc /scannow /offbootdir=X:\ /offwindir=X:\Windows

When complete, remove the install disk and reboot.

Go Start - type cmd - right click on cmd and select Run as administrator and enter sfc /scannow

That should hopefully report no integrity violations but let me know if it reports anything different.

You may need to perform another repair install if things still don't work.
