Microsoft releases for all machine at the same time, out of my 7 notebooks, only one had message to upgrade but I manually did the rest on one day. Tomorrow I will do few more machines for my children they are allow to visit me this weekend after more than 9 months lock down due to Covid-19.
Please
(a) download ISO file from the following link (would take around 30mins)
https://www.microsoft.com/en-us/software-download/windows10
(b) mount ISO file as DVD drive

(c) run Setup (would take from 40 to 60mins depending on your machine)
(d) follow onscreen instructions
Regards.
