What Causes Windows Update Error 8024a000?

The Windows Update error can be caused by a wide range of factors, including:

  • Windows Update glitch – This issue can occur due to a recurring WU problem. Under certain circumstances, the updating component will become stuck and unable to install any new pending update.
  • Windows update service is stuck in a loop – This issue can also occur if one or more Windows services are either started or stopped.
  • WU associated DLLs are not registered properly – Windows Update relies on dozens of Dynamic Link Library files when searching for and installing pending updates. If any of these files is missing, then WU won’t run properly.
  • System File Corruption – A single corrupted file can effectively break the whole WU component.
  • RST driver is missing from the Windows installation – If your computer is missing the Rapid Storage Technology Driver or it’s using a severely outdated version, running into this error can be expected.
  • Third-party AV is closing ports used by Windows Update –Third-party security tools can be so overprotective that they have a tendency of closing legitimate ports used by Windows Update.

Fix #3: Performing SFC and DISM Scans

Both DISM (Deployment Image Servicing and Management) and SFC (System File Checker) are built-in utilities capable of repairing system files. The only difference is they do it in different ways.

Here’s a quick guide on running an SFC and DISM scan from an elevated Command Prompt:

  1. Press Windows key + R to open up a Run dialog box.
  2. Then, type cmd inside the text box and press Ctrl + Shift + Enter to open up an elevated Command Prompt.
  3. When you’re prompted by the UAC (User Account Control), click on Yes to grant administrative privileges.
  4. Type in the following command and press Enter immediately to start the SFC scan: sfc /scannow

When the procedure is complete, you can safely close the elevated command prompt and restart your computer to see if the issue has been resolved at the next system startup.

If the same issue is still occurring even after you’ve performed the SFC scan, perform a DISM scan this time using this command: DISM /Online /Cleanup-Image /RestoreHealth

Once the scan is finished, perform one final restart and check if the issue has been resolved once the next startup sequence is complete.


Windows Update error 8024a000 is quite easy to resolve as long as you notice the error immediately. Otherwise you’ll be exposing your computer to vulnerabilities that might bring danger to your computer. The steps above should be enough to resolve this error and get Windows Update functioning properly again.
