Now let's go through that in detail, but first make sure you create a restore point.

Run Windows update troubleshooter

Let's see if that helped. If not, manually reset the components and check.

Manually reset Windows Update components

Sometimes this problem can appear due to corrupted system files. Therefore, if you are still having problems after installing Windows updates manually, restart the Windows components by following the instructions below:

To do this, first open the advanced command line.

Now type the following commands and press Enter after typing each command to stop Windows Update and other related services from running.

stop bits.
wuauserv web stop web
stop application
week stopcryptsvc

Now delete all qmgr*.dat files from your device. To do this, type the following text code at the command prompt and press Enter to run.

Remove "%ALLUSERSPROFILE%ApplicationDataDataMicrosoftNetworkDownloaderqmgr*.dat

At this point the system may ask for your confirmation by typing Y to confirm.

Next you need to rename the SoftwareDistribution and catroot2 folders. So type the following command in the Command Prompt window and press Enter.

Ren %systemroot%SoftwareDistribution SoftwareDistribution.bak
Ren %systemroot%system32catroot2.bak

To reset the BITS service and Windows Update service to the default security descriptor, type the following commands in the Advanced Command Interpretation window. Also, press Enter after each command to run it:

sc.exe sdset Bits D: (A ;; CCLCSWRPWPDTLOCRRC ;;; SY) (A ;; CCDCLCSWRPWPDTLOCRSDRCWDWO ;;; BA) (A ;; CCLCSWLOCRRC ;;; AU) (A ;; CCLCSWRPWPDTLOCRRC ;;;;

sc.exe sdset wuauserv D: (A ;; CCLCSWRPWPDTLOCRRC ;;; SY) (A ;; CCDCLCSWRPWPDTLOCRSDRCWDWO ;;; BA) (A ;; CCLCSWLOCRRC ;;; AU) (A ;; CCLCSWRPWPDTLOCRRC ;;;;

Then run the following command to navigate to the System32 directory:

cd/d %windir%system32

At this point you need to re-register the BITS (Background Intelligent Transfer Services) and DLL files associated with Windows Update. To do this, type the following commands one by one and press Enter after each command:

regsvr32.exe atl.dll
regsvr32.exe urlmon.dll

regsvr32.exe wuapi.dll
regsvr32.exe wuaueng.dll
regsvr32.exe wuaueng1.dll
regsvr32.exe wucltui.dll
regsvr32.exe wups.dll
regsvr32.exe wups2.dll
regsvr32. exe wuweb.dll
regsvr32.exe qmgr.dll
regsvr32.exe qmgrprxy.dll
regsvr32.exe wucltux.dll
regsvr32.exe muweb.dll

After successfully re-registering the BITS files and the Windows Update DLL file, you need to reset the network settings.

So type the following command line and press Enter each time.

reset nets winsock reset
proxy server netsh winsock

Now restart the interrupted services like background intelligent service, windows update service and crypto services.

So, type the following command line in the Command Prompt window and press Enter after each command.

Network Startup
Bits Wauserv Network
Startup Pure PVC Startup Applications Startup
Cryptogram
Exit
