Windows Update depends on:

  • Windows Installer

Make sure all are:

✔ Running
✔ Set to Automatic

If any are stopped → Start them manually.


Fix 3: Reset Windows Update Services via Command Line

net stop bits
net stop cryptsvc
net stop msiserver

Then reset components:

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

net start wuauserv
net start bits
net start cryptsvc
net start msiserver

Restart PC.

Fix 4: Check Group Policy Settings (Advanced)

If Windows Update service keeps disabling itself:

  1. Press Windows + R
  2. Type:
gpedit.msc

Navigate to:

Computer Configuration → Administrative Templates → Windows Components → Windows Update

Ensure policies are:

✔ Not configured

If disabled by policy, enable update settings.

Fix 5: Run SFC and DISM

Corrupted system files can break update services.

Open Command Prompt (Admin):

sfc /scannow

After completion:

DISM /Online /Cleanup-Image /RestoreHealth

Restart PC.

This is especially helpful if updates repeatedly fail.


Fix 6: Check for Malware

Some malware disables Windows Update service to prevent security patches.

Run:

  • Full Windows Security scan
  • Or trusted antivirus scan

Remove any detected threats.


Fix 7: Repair Windows (Last Resort)

If service refuses to start even after reset:

Use Windows 11 Installation Assistant:

  • Choose “Upgrade this PC now”
  • Keep personal files and apps

This repairs system files without data loss.


Why Does Windows Update Service Stop Automatically?

Possible reasons:

  • Corrupted system files
  • Registry corruption

  • Malware
  • Failed update process

Avoid registry cleaner software — they often break services.
