Pre-scan result

[johnno]

hi, i am a first timer,just downloaded tweaking.com windows repair. Ran a pre-scan. Result is as follows.
These files are Possibly corrupt (Bad Digital Signature):(Total 1)
C:\Windows\servicing\Packages_for_KB971557_client_1~31bf3856ad364e35~x86~~6.0.1.0.mum.
These files need to be replaced as the system file checker doesn't scan or replace some of these files. So now it tells to replace them manually. OK thats were im stuck can anyone please tell me how to do this.

I can repair the reparse  points, and my environment variables are ok.
Any help would be greatly appreciated.
 PS bit of a computer dummy lol

Go ahead and run all the repairs in windows safe mode (Have it do a registry backup first) and then see how things go.
