My friend is running windows vista and it's not working any more. I've run diagnostics and found that three files in the C:\Windows\System32 folder have corrupt ACLs. System repair fails because windows can't access the files to overwrite or repair those files.
I suspect that her antivirus program accidentally quarantined them.
Now the computer cannot boot because it cannot read these files.
I have access to startup recovery tools, a vista disk, and command prompt. Is there a way I can manually or automatically repair or replace the damaged files?
As I said before, Windows Repair has thus far proved inadequate.
