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.

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

    I ran the test thing and it says
    C:\Windows\System32>reg load HKLM\COMPONENTS c:\windows\system32\config\components

    The operation completed successfully.
    And I'm trying the update right now. Thank you for your help!

    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.

    See if that resolves the issue.

    Thank you so much Ramesh

    The sfc /scannow function has finally started to work and fixed whatever corrupted files it was finding, and the windows update looks like its starting to work as well now ... what a relief

    Its been a battle going through numerous solutions like offline downloads, trying to mount files that wouldn't mount, resetting windows, registry edits etc etc, all to no avail, until I found this post ...

    So thank you again Ramesh, you're a life saver
