So ive had this problem for a long time now.. Windows update will not install and my firewall will not turn on (grayed out). I did a scan in the CMD and it says there is missing or corrupted files. I tried to do a ton of fixes on it an nothing is working. Also my firewall says "update your firewall settings but when i try to click on the use recommended setting its shoots me another error code (0x8007045b). I have a feeling that those 2 problems are connected can anyone help me?

Note: Ive also tried these in the powershell but that didnt work either.

Ren C:\Windows\System32\catroot2 Catroot2.old

net start cryptSvc

    I don't have a good idea what you did to the file, but THANK you a hundred times!

    With kind regards,

    Peter

    Hi Piers,

    Please do the following:

    • Open the folder "C:\Windows\System32\Config"
    • In the above folder, rename "DRIVERS" to "DRIVERS.OLD"
    • Download DRIVERS.zip
    • Unzip and extract the file "DRIVERS" to the desktop.
    • Move "DRIVERS" from your desktop to "C:\Windows\System32\Config".
    • Restart Windows.

    Ok, You haven't copied the rectified Components file I sent you.

    • Open the folder "C:\Windows\System32\Config"
    • In the above folder, rename "COMPONENTS" to "COMPONENTS.OLD"
    • Copy the downloaded COMPONENTS file (unzipped) to "C:\Windows\System32\Config".

    Without doing the above, the problem can't be fixed.

    The components file I sent you loads fine here. I'm unsure if you've copied it correctly.

    Please run this command:

    • certutil -hashfile "C:\Windows\System32\Config\components"

    Post the output.
