Windows 7: Laggy Windows 7, possibly due to corrupt files

Laggy Windows 7, possibly due to corrupt files

When googling a fix on a laggy Windows 7, one of the steps for diagnosis was to open up cmd.exe as an admin and run sfc/scannow. And after doing so, at 29% Verification, cmd notified me that:
"Windows Resource Protection found corrupt files but was unable to fix some of them."

And I when I attempt to open the log, it says access denied, probably because I'm not using the correct program.

It may just be the file is locked rather than using an incorrect program. Try copying the file to your Desktop, then open the copy.

Ok, I can open the file now, what exactly should I be looking for?

So I should just run the Windows 7 Installation CD to fix the corrupt files since running cmd won't fix them?

You might try running SFC at boot

SFC /SCANNOW : Run in Command Prompt at Boot

It may need to be run 3 times to repair any errors. If indeed it cannot repair them, then yes, you can try manually replacing them per Option Three mentioned.

After creating a repair disk and attempting the repair via cmd with the command:
"sfc /scannow /offbootdir=c:\ /offwindir=c:\windows"

It gave me the message saying something along the lines of "Windows Correction cannot begin repair"

So I resorted to System Restoring to my most recent Windows update which was a critical update, around 4-5 days ago. If that doesn't work, then I am planning to reinstall from scratch.

Use the OEM tutorial if Windows came preinstalled, if not then use the Clean Install instead.

Hopefully, the System Restore will work and sort things out.

Hope this helps,
