Windows 10 - feature update 20H2 failed to install

Question

Hello,

I have a Dell XPS 15 (7590) with Windows 10 Home and I've tried to install Feature Update 20H2, but it keeps failing.
This is my update history, the most frequent code I got is 0x800700a1.

I tried using Windows Update Assistant, as I read others solved the problem this way, but for me it didn't work.

What else should I try?

Thank you !

Answer 1

Hi all, had this issue since the feature update back in March or something, but here was my fix. Removing Malwarebytes didn't solve my issue, so maybe this can help others

Navigte to C:\Users\Default\AppData\Local\Microsoft\Windows\WSUS and delete the .ini file in there.

Try downloading the update again

I had this problem and none of the prior suggestions worked for me, but this did solve the problem:

https://www.microsoft.com/en-us/software-download/windows10ISO

Download the Windows Nov 2021 Update release

It took the better part of a day to install but it did eventually resolve my issues and I'm able to take subsequent updates again.

Be sure to back your system up to your satisfaction before doing this, your mileage may vary, etc, etc.....
