Hey,
Wanted to update community, I finally received the update.
Some points...
- directly received 20h2 update (it is inclusive with previous updates)
- Microsoft issues page still lists all the problems as it is but I received via normal Windows update route so I updated it.
- my machine is decent hardware if not the most premium and very good Internet connection ..... It took more than 11 hours...
Machine is working fine... Fingers crossed..!
Best luck guys... I hope you all also receive it in couple of days.
