I guess nobody has used this tip because it won't work unless you run it via the Command Prompt AS ADMINISTRATOR

Open up your Command Prompt window AS ADMINISTRATOR (Start Menu-->Windows System-->Right Click on "Command Prompt"-->select "More"-->Run As Administrator)

-Or-

[Windows]-[x] and select Command Prompt(Admin)

-Or-

If you're running cmd.exe from the System directory or from a Command Prompt icon on your desktop, right-click and select "Run as Administrator".

Then typing in the sfc and Dism commands should work fine.

Sorry for any inconvenience this omission caused.
