Quick Recovery: Reviving a Vanished Windows Update

The Windows Update service is responsible for downloading and installing Windows updates over the internet. You can start, stop, and manage this service as necessary from the Windows Services app. But what if the Windows Update service suddenly goes missing from your computer?

If you’re baffled by the sudden disappearance of the Windows Update service, fret not. This guide contains some potential fixes that should help restore the Windows Update service in no time.

1. Run the Windows Update Troubleshooter

Both Windows 10 and 11 include a few troubleshooters to help you with common system-level issues. One of them is the Windows Update troubleshooter. While it does not guarantee to bring back the Windows Update service, it’s a troubleshooter worth trying nonetheless.

To run the Windows Update troubleshooter:

Open theStart menu and click thegear icon to launch the Settings app.
In theSystem tab, selectTroubleshoot .
Go toOther troubleshooters .
Click theRun button next toWindows Update .

Wait for the troubleshooter to scan your computer and do its thing. If any issues are detected, it will try to fix them on its own.

2. Run the SFC and DISM Scans

Corrupt system files can also cause some Windows services or default apps to disappear from your computer. The System File Checker and Deployment Image Servicing Management are two command-line tools that can help you detect and restore any damaged system files on Windows. Here’s how to run them:

Click the magnifying icon on the taskbar or use theWin + S shortcut to open the search menu.
Typecommand prompt in the search box and selectRun as administrator .
SelectYes when the User Account Control (UAC) prompt appears.
In the console, paste this DISM command and hitEnter :
DISM.exe /Online /Cleanup-image /Restorehealth
To run the SFC scan, input the following command and pressEnter :
sfc /scannow

After the scan is complete, restart your PC. Following that,open the Services app and see if you can find the Windows Update service.

3. Scan for Malware

If the Windows Update service is still missing, you might be dealing with a virus or malware infection. To check for this possibility, you’ll have to run a full system scan using the built-in Windows Security app. Here are the steps for the same.

Open the search menu, typeWindows Security in the box, and select the first result that appears.
In the Windows Security app, switch to theVirus & threat protection tab.
UnderCurrent Threats , clickScan options .
On the next screen, select theFull scan option.
Click theScan now button.

Wait for Windows to finish scanning the computer and, if threats are found, apply the recommended fixes.

4. Restore the Windows Update Service Manually via the Registry Editor

It’s possible that a recent update or system change has messed up some of the registry files, causing the Windows Update service to go missing. If that’s the case, you can try restoring the Windows Update service manually by editing theWindows Registry . However, you should only do this if you’re comfortable editing registry files.

If you decide to use this method, make sure you back up all the registry files before proceeding. If you need help, check our guide onhow to back up and restore registry files on Windows and follow the steps outlined there.
