    ooooh! That sounds like you're MMC snap-in's are broken too. Before you do any thing else open an Admin command prompt and cut and paste this in there then reboot:

    Code:
    Dism.exe /online /Cleanup-Image /StartComponentCleanup&sfc/scannow&Dism /Online /Cleanup-Image /RestoreHealth&sfc/scannow 
    It'll take a while but it cleans the WinSxS folder and tries to fix corrupt system files.

    You have to use an elevated(run as administrator) command prompt. When you cut & paste it from the code box, make sure you get all the code. Then the box will stay and you can see what it's doing. please try again. Here it is w/o the code box:

    Dism.exe /online /Cleanup-Image /StartComponentCleanup&sfc/scannow&Dism /Online /Cleanup-Image /RestoreHealth&sfc/scannow

    Have you rebooted and can you access the task scheduler or event viewer now?
