KB4586853 CU Windows 10 v2004 build 19041.662 and v20H2 19042.662 Win Update

Still no solution why I cant update to 662 , while 661 went smooth !
Tried 662 several times the same way as 661 , still no luck or solution.............

Will quit trying till working solution appears !

661 and 662 are unofficial releases (aka: leaked). They are most likely internal releases that Microsoft is still working on, so this is why they are getting updated like this.

Thanks @Shawn for this explanation. It makes more sense to me now.

Same issue, same error, and no issues with installing the 661 cab file

As of 11:15 EST, I still can't get 662 to download. It goes anywhere from 20-40% then fails.

" Failed for me too. I'll leave it until it's officially released. "..............wise decision , will do the same ( after trying 4/5 times ) !
Maybe a "Black-Friday joke " from MS ...........

Still did not find any answer about the difference in MBs ; 661 is 372MB ( this update went fine) ,662 is 369MB ( this update fails ) , should be 372MB also ..........!!?

@Brink, thanks, got it.
