I have uploaded windows 11pro, 22H2 in 4 computers in total following the above instruction. I could upgrade all of them in 1 chance without any hiccup of any kind. Of the 4 two have Tpm 2 and came with windows 10, but unsupportive processor. The other two are unsupported in all aspects, originally came with windows 7 and 8 each. Upgraded to windows 10, then dual boot to win 10 and win 11 21H2. I could upgrade flawlessly. The instructions are thorough. However one has to follow religiously. Those who got stuck in the mid way, I would suggest them to start all over again. The steps are virtually failproof. One can open two computer side by side. The one which needs to be upgraded and the other to follow the instructions so that you do not miss or mix up a steps. Internet disconnection is also important and do not reconnect until everything is complete. However before proceeding with the steps one thing I may suggest, that the sleep function should be disabled (it may be set to never)- during the upgrading process so that the downloading and installation process could continue flawlessly.
By the way I am an absolute layman.
The following models I have upgraded.
AMD PRO A10-8770 R7 3.5Ghz (2 Desktops)
TOSHIBA Sattelite P50t-A , i5-3337u ( laptop)
DELL Inspiron One 2320 i3-2120 (All in one)
