Windows 10 Updates fails to install even after multiple attempts.

Checking for updates after following the steps, Will inform on the progress of the update process and whether this solves it or nope. Thank you for the suggestion.

[Update]
The Trick didn't work.





The Security Update for Windows 10 for x64-based Systems (KB3074681) which was available, failed to install. And the same story again..

 

Windows Updates failed to instal

I just did step one and they have just all installed.... thank you so much.... it was quite frustrating having that update window pop up every 5 minutes and failing to instal every time

Thanks mate

 

Windows 10 version 20H2

The computer in question had Windows 7 on it and there was not an option to uninstall the 20H2 update. So I have reverted back to Windows 7. Is there a way to download and install Windows 10 version 2004? The games will work on that version but not the
20H2 version.

Thanks
