KB5001649 CU Windows 10 v2004 build 19041.870 and v20H2 19042.870  

I am getting this CU through WU but when I select Download and Install WU just does nothing.

WU and Standalone both with errors.

MS screwed this & other similar updates again

that's what happens when MS got rid of their old QA team

No problems here

YEEEES ! This update fixed my Canon MP520 !!

Same problems here, was stuck at 1% now not even starting to download.

The windows update failed three times.


It got installed successfully by Microsoft update catalog.

No problems now.

Same error as other using Windows Update. Seems to not even try to download anything.
Will give it a day or two to see if it sorts out.
