Microsoft provides fixes for a lot of bugs as well as upgrades their software through Windows Update. Thus, your PC is bound to find trouble if it is not working.

The Windows Update Service or wuauserv handles the Windows update feature for the detection and provision of required updates to the computer. So, the Windows updates will not work and show Error Encountered while checking for updates if this service goes missing.

And on top of that, you will not even find Windows updates listed in the services list. But don’t panic. We have brought forth the working solutions to restore the Windows update service on your PC.

How to Fix the Missing Windows Update Service

The Windows updates service can disappear due to system file corruption, virus infection, or registry error which can be fixed easily.

So, let’s move through the fixes right away.

Run Windows Update Troubleshooter

The built-in troubleshooter in Windows can easily restore the missing Windows update service on your PC. Let’s see how you can use it.

Run DISM and SFC Scan

Sometimes, the system files can get corrupted by virus infection or some other means. This can cause the system services to malfunction, including the Windows update services. To fix this, you can run the DISM scan. It will repair the damaged system files and fix your problem of missing Windows update service.

However, the DISM scan works by downloading healthy files through Windows updates server. Since your Windows update itself is not working, you should use another source of Windows to get the healthy files. Thus, you should first download the Windows ISO file and use it as the source.

  1. Press Windows + ‘I’ to open Settings and go to the About section.
  2. Note the architecture, build, and version of your windows.

  5. Press Windows + ‘R’ and type cmd.
  6. Press Ctrl + Shift + Enter to open Command Prompt with administrative privilege.
  7. Enter the command dism /online /cleanup-image /restorehealth /source:D:sourcesinstall.wim /limitaccess.

    For our computer, the installation drive of mounted ISO is “D:”. So, it may vary as per PC. You will have to replace “D” with the drive letter where the ISO file is mounted.

  8. Restart your PC.

The Windows update service should be back now.

Repair Registry Entry

If the registry entry of Windows Update gets corrupted or deleted by some means, you will find the Windows Update Service missing. So, you should restore and repair the entry to fix the issue.
