I repeat question I asked in Windows forum also here in Insider forum because I believe user here
may have also interest to know that, but all doesn't necessary read Windows forum:
Eddie:
What's the difference of these two warnings in Settings / Update / WIP and
what happen these two PC's when Windows 11 is officially released?
#1) (Yellow) Clean install of 19043.XXXX, linked to WIP and updated to Win 11.
#2) (Red) Exception for Dev users before 6/24, build 21390 updated to Win 11.
I believe your comment "If you are running an Insider device that does not meet the minimum hardware requirements, but was allowed to update to 11 you will be opted out of flighting at general availability an must perform a clean install of Windows 10." match for #2, but how about #1?
