Windows Update Service registration missing corrupt

Windows Update should be an essential aspect for every user of the Windows Operating System.

If the system does not get updated on time, it might face all kinds of problems such as security issues, performance issues, etc.

Quick tip:

Most computers get their updates automatically but sometimes, although the Update Service is set on the Automatic Mode, the system is not able to install the available updates.

If this happens, please try to run the Windows Update Troubleshooter first. Go to Settings, then to Update & Security, and click on Troubleshoot to launch the troubleshooter.

If this doesn’t fix the problem, you can use one of the methods described below.

How can I fix the Windows Update Service registration problem?

  1. Disable the antivirus software
  2. Check Windows Update Related Services
  3. Run Windows Update Commands
  4. Run a SFC scan
  5. Turn off and on the Windows Firewall

1. Disable the antivirus software

You can also try to turn off the antivirus software temporarily. Sometimes, your antivirus tool may prevent your computer from installing the latest updates.

As a result, simply disabling your antivirus may help you fix this problem. If it doesn’t you will need to remove your antivirus completely.

We say completely because by using the regular uninstalling technique, many programs leave some leftover files behind. In time, that file accumulation may lead to system slow down and other problems.

That’s why we recommend using specialized software like IObit Uninstaller to remove your antivirus or any other program for that matter.

It’s extremely simple to use and once you run it, you will be amazed at the free space you will regain after the operation.

When you’re done with uninstalling the old antivirus and performing the OS updates, you shouldn’t leave your PC unprotected so we recommend switching to a safer and unobtrusive antivirus like VIPRE Antivirus Plus.

This security solution not only doesn’t interfere with your system or the update process but it’s also light on your PC.

VIPRE Antivirus Plus comes with a feature called RapidScan that helps speeding up the scanning process. When it starts a regular, programmed scan, it skips the files that were found safe in previous scans.

This security solution also has anti-threat protection and cloud-enabled security. It also offers ransomware protection so you are safe against those types of attacks.
