2. Edit Wuauserv settings

Wuauserv is a Windows system service that contains the wuauserv.dll library. This is a critical tool and takes care of the Windows Update process. If there’s an issue related to this service, this may start the Language Pack error on the computer. To address this bug, follow the below guideline –

Open the Run dialog by pressing the Win + R altogether.
In the void, type regedit using your keyboard then hit the OK button.
Click the Yes button if prompted by UAC.
When the Registry Editor starts, navigate to the below location –

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

Jump to the right side and double-click to open the key UseWUServer.

Note: In case you don’t find this key, right-click anywhere on the blank area and select New > DWORD (32 bit) Value. Rename this entry to UseWUServer.

Make sure to change the Base to Decimal and put “0” inside the Value data field.

Lastly, hit OK to confirm these changes and close the registry.

After modifying the registry, make sure to clear the Windows Update Cache folder using the below steps –

Click the Start button and type cmd.
Right-click on the Command Prompt option and select Run as Administrator.
If prompted by UAC, hit Yes.
Next, run these codes one by one followed by the Enter key separately –

ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 catroot2.old
net start bits
net start wuauserv

net start cryptsvc

After running the above codes successfully, come out of the Command prompt area and Restart Windows.
