[Fix] Missing Windows Update (wuauserv) Service in Windows 10/11

The Windows Update service (wuauserv) enables the detection, download, and installation of updates for Windows and other programs. If this service is disabled, users of this computer will not be able to use Windows Update or its automatic updating feature, and programs will not be able to use the Windows Update Agent (WUA) API.

If the Windows Update service is missing in the Services MMC console in your Windows 10 or Windows 11 computer, use the registry fix in this article to restore it.

[Fix] Missing Windows Update (wuauserv) Service in Windows 10/11

To restore the Windows Update service on a Windows 10 or Windows 11 computer, follow these steps:

  1. Download wuauserv-service.zip and extract the contents to a folder.
  2. Double-click on the enclosed file wuauserv-windows-10-11.reg
  3. Click Yes to apply the settings to the registry.
  4. Restart Windows for the Windows Update service to get registered correctly.

(Note that the registry files have been tested on Windows 11 Version 21H2 OS Build 10.0.22000.708 and Windows 10 Version 21H2 OS Build 10.0.19044.1706. The Windows Update service registry settings are exactly the same on both Operating Systems.)

The Windows Update service registry key is located at:



HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv

Contents of the Registry file

By default, the Windows Update Service (wuauserv) service is set to Manual start.

I hope the above registry fix has restored the missing Windows Update service to the Services console in your Windows 10/11 device.
