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.

    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.

    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.

    Ramesh,

    Thanks very much for your patience and expertise. I downloaded the rectified components file and placed into the directory as you specified and the system now correctly performs windows update. Apparently I installed the incorrect components file the first time. Your contributions to helping users resolve problems is highly commended and you likely saved me 100 hours of reloading windows, drivers and apps and much frustration.

    Again, thank you very much
