Just wanted to post one more thing. I decided to check my brand new freshly installed Windows 8.1 pro by using SFC and DISM. Guess what? Dism found and fixed corruptions, and SFC found and could NOT repair all of the file corruptions. Keep in mind this installation is only 2 days old! SFC could not repair the following two files;

Fortunately I was able to find the proper version of these files and then use SFCFix.exe to repair my problem. WHEW!! Kudos to whomever wrote this utility. SFC and DISM both are now completely clean, so I went ahead and made more back-ups....
Regards!
