    Windows Update left system restore unusable

    I am not sure this is the correct forum for this. If not, please redirect me.

    Windows 8.1

    After last Windows Update I get on restart: Error from WerFault.exe:
    "instruction at 0xcd730bff references memory at 0x0000000. Memory location cannot be written."

    I think the Registry was left corrupted by Windows Update.

    This error is preventing me from running Windows Defender, from running System Restore, from installing a Registry Cleaner, and much more. The Windows "Consent UI" is throwing the "0x0" error when I try to do the install the Registry Cleaner.

    One idea I have is to load System Restore in safe Administrator mode, then restore the pre-Windows Update version.

    Anyone have info on how to get to System Restore Administrator in safe Administrator mode? Any other ideas?

    Try sfc/scannow to repair possible corrupt files. Run DISM if needed (bottom of page) and let us know results.

    SFC /SCANNOW Command - Run in Windows 8 (Try Option 2 first)

    May want to try to scan with Malwarebytes and uninstall upates if possible. Final option may be a System Refresh which you would not lose any files, possibly some add-ons.

    from installing a Registry Cleaner

    Many will advise registry cleaners are not a good idea.

    No way to fix

    Thanks for suggestions about software to download to maybe fix this. But the problem prevents execution of a download. Not only that, but the OS refuses to let me boot from a CD drive where I could have loaded a bootable image with fix software.

    Only solution was the 'refresh' my PC. So I will be spending next few days reinstalling all my apps.

    Lesson: Windows Update can corrupt your OS in a way that leaves you dead in water no matter how much you backup stuff.

    SFC/scannow is a command prompt, not a software download.

    Refresh is good option to insure registry is back to specs. As stated, many advise against registry cleaners.
