What do I do if SFC detects but cannot fix a problem?

//
I run Vista, SP2, Home Premium. The results of “sfc /scannow” show a couple of files that cannot be repaired. It couldn’t re-project a corrupted file; the source file in store is also corrupted. PublicKey neutral in the store, hash mismatch. Now, I don’t find this problem mentioned in your archives. I see the problem addressed on the web, but the various solutions presented seem either overly complex or too simplistic for me to comfortably try them. I see some people have tried these “solutions” that (after getting feedback that the files are restored) run “sfc /scannow” again and receive the same error indications. Is this a case of a problem that is not a problem? What are your thoughts? How would you proceed to restore these files?

The System File Checker (SFC) uses several techniques to detect that one or more of your system files have been either inappropriately replaced or damaged. SFC then tries to repair the problem.

Unfortunately, it can’t repair everything. In your case, that puts you in a hard spot.
