Windows update failed (Install error 0x800703f1)

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

    0x80070003 is a different issue. The CBS logs need to be checked.

    If this is for Windows Server, I'd suggest posting this in the Q&A forum. https://learn.microsoft.com/en-us/answers/questions/

    To collect the CBS logs, please open admin PowerShell and run:

    Compress-Archive C:\Windows\Logs\CBS -f (join-path ([environment]::GetFolderPath('Desktop')) \CBS.zip)

    This creates a file named CBS.zip on your desktop. Share it on OneDrive and post the link in the Q&A thread you create.
