Well, just wanted to say thanks and tell you that I have fixed the corruption problem by performing the following steps:
1. I opened an elevated command prompt (I have Windows 8.1 installed)
2. I typed "cd /D %windir% " (without the quotation marks) at the prompt
3. I then typed this command "icacls * /T /Q /C /RESET" (once again without the quotation marks) at the prompt
4. I waited for the command to be executed completely, then ran the SFCFix tool again and no corruptions were detected.
Thanks for a great tool and a great community.
