How to Fix Error 0x80004005 on Windows PC


Keeping your Windows computer up-to-date is extremely important. The latest updates often pack security improvements, as well as new features. Unfortunately, upgrading your machine to the latest Windows OS version is not always possible due to all kinds of unexpected update errors. In this quick guide, we’ll focus on error code 0x80004005 and how you can get rid of it.

Fix: Windows Update Fails with Error 0x80004005

Run the Update Troubleshooter

First things first, check if the built-in Windows Update troubleshooter can fix the problem that’s triggering error code 0x80004005.

Navigate to Settings, select System, and click on Troubleshoot. Then, select Other troubleshooters and run the Windows Update troubleshooter.


After running the tool, check for updates again.

Restart the Windows Update Services

If error code 0x80004005 persists, try restarting the Windows Update services. The quickest way to do that is by running a series of commands via Command Prompt.

  1. Launch Command Prompt with admin rights.
  2. Then, run the following commands one by one:
    • net stop bits
    • net stop cryptsvc
    • net stop wuauserv
    • net stop msiserver
    • Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

    • net start wuauserv
    • net start msiserver
  3. Restart your computer and check for updates again.

Disable All Background Programs

If you still can’t install the latest OS updates, maybe one of your background programs is interfering with the update process. This includes third-party antivirus, firewall, and antimalware tools. They may sometimes flag the updated files as suspicious and prevent your machine from installing them.

Launch the Task Manager and click on the Processes tab to force-stop background programs to list all the apps and programs running on your machine. Then, right-click on the program you want to close and select End task.

  1. Launch Command Prompt with admin rights.
  2. Run the following commands one at a time:
    • DISM /Online /Cleanup-Image /RestoreHealth
    • scf/ scannow
  3. Restart your computer and try again.
