What Is the Windows Update Service, and Why Is It Missing?

The Windows Update Service (also known as wuauserv) is a critical background process responsible for managing and delivering Windows updates. If this service is disabled, missing, or corrupted, your PC won’t be able to download or install updates.

Common reasons the service might be missing:

• Manual or accidental service disabling
• System file corruption
• Malware interfering with system services
• Errors after major Windows 11 updates

Step 1: Check the Windows Update Service in Services Manager

First, let’s check if the service is really missing or just stopped.

1. Press Windows + R, type services.msc, and hit Enter.
2. In the Services window, scroll down to Windows Update.
3. Check the Status and Startup Type:

   • Status should say Running.
   • Startup Type should be Automatic (Delayed Start) or Manual.

If Windows Update is missing from this list, proceed to the advanced steps below.

If it’s there but stopped:

• Right-click the Windows Update service and select Start.
• Right-click → Properties → Set Startup type to Automatic (Delayed Start) → Apply → OK.
• Try running Windows Update again.

  2. Under the Services tab, check Hide all Microsoft services.
