How can I fix the Windows 10 update error 0x80070026?
- Check your antivirus
- Delete the content of the Temp folder
- Copy the $$PendingFiles folder
- Run DISM
- Refresh your PC
- Run the Windows Update Troubleshooter
- Reset Windows Updates components
- Install updates manually
1. Check your antivirus
Quite frequently, your antivirus prevents you from updating your computer. To check if your antivirus tool is the culprit, temporarily disable it and then hit the Check for updates button.
Many times, disabling your antivirus won’t be enough so you will need to uninstall it completely. If this proved helpful, that means you should consider switching to another solution.
We recommend VIPRE Antivirus Plus, a powerful security solution with a modern, simple to use interface that, most importantly, doesn’t interfere with your updates.
Even if it poses like a very simple antivirus, this clever tool has an Advanced Active Protection feature that uses machine learning to identify and block even polymorphic malware.
VIPRE Antivirus PlusForget about update errors while using VIPRE. It keeps your PC perfectly safe while it doesn't interfere with your system.
2. Delete the content of the Temp folder
- Reboot your PC.
- Log in with your administrator account.
- From the “C:” partition (or your main partition) double-click the Users folder.
- Double-click the itnota folder.
- Open AppData, then go to Local.
- Now, open the Temp folder and delete all the contents.
Note: Before attempting the steps above backup call your important data like files and folders.

robocopy /copyall /mir /xj G:$$PendingFiles H:$$PendingFiles

8. Install updates manually
If the Windows Update service is still not working, try to install the problematic updates manually.
For example, if you’re trying to install the latest hardware driver updates, go to the manufacturer’s website and get the updates from there.
If you’re trying to install the latest Windows patches, go to Microsoft’s Update Catalog, enter the KB number of the respective update(s) and hit the download button.
If you’ve carefully followed the methods above, you now have a working Windows Update feature on your device.
