Auto Update of SFC/Scannow with Win7 SP1

Does the SP1 upgrade automatically upgrade the SFC/Scannow files in Win7?

How do I do a corruption resolving upgrade of Win7Premium w/ SP1 starting with a Win7 pre SP1 Upgrade Install disk?

I assume that a re-install of Win7, impacting only System files, is superior to a simple SFC/Scannow fix.

Updates to Windows keeps c:\windows\winsxs current and SFC will use that if it needs to in order to correct system files.

So, yes, SFC keeps up-to-date.

You normally do not need to use a CD source to run SFC. I never have: Vista, Windows 7 or Windows 8. You only need a CD source for Windows XP.

So then the answer to your last question is that if SFC cannot effect a good repair, then a reinstall will be superior. However, for modest problems, an SFC repair is just fine. SFC cannot repair every problem, whereas a reinstall can cure everything (except hardware problems).

1: you are correct (wasn't able to test using a boot from cd and run sfc /scannow could only use the working operating system.
2: I would download a newer disk .. i.e. Microsoft Digital River Windows 7 Home Premium English x64

3. Please elaborate
4.  You have to start the installation from the existing operating system and you must use a service pack 1 disk

Thanks everyone... useful replies!

Do you have a good "How To" link for a "Reinstall of Win7 SP1" that does not impact Programs and Docs... only System files.

Does the Digital River link include SP1, and latest updates?

I did an SFC Scan from Safe Mode... is there a better way?

As I noted earlier, SFC will not fix all problems and it appears it did not here.

Another way for repair in place is a Repair Install (different from a startup repair). See bellow:

You should back up your computer before doing a Repair Install, and if that does not work, then a full format and reinstall of Windows is called for.

Thanks... but this looks like a simple Startup Repair not a full Re-Install of the System files.

That is why I posted the Repair Install link. There is more to fixing a computer that simply System files, and a Repair Install is the last hope before starting over.

The digital river link only has SP1 and not updates since then.  Boot into an administrator account OR put in the disk and do from a command prompt

runas /user:administrator x:setup  
where x: represents the dvdrom drive

and do an UPGRADE  install
