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

    Hi Ramesh,

    Have the same issue with drivers.
    C:\Windows\system32>reg load HKLM\DRIVERS c:\windows\system32\config\drivers

    ERROR: The configuration registry database is corrupt.

    DRIVERS.zip

    Can you please check, what is wrong there?

    Thanks

    Hello Ramesh

    I found your support string after I received the 0x800703f1 error. It seems I am having the same problem with my DRIVER file. I ran the command in your first post for both the COMMAND and DRIVER file. The COMMAND completed successfully, but the DRIVER said the database was corrupt.

    Would you please take a look at it?

    Thank you
