Hi CK,
Not sure if you were aware, had to total clean install Main Desktop last week due to daily BSOD. Went ahead with using RP ISO and updating to 19043.906.
Interesting enough, today's CU kb5001330 took the build up to 19043.928 and did allow me to opt out of Insider program RP putting the device back to Get Started for Insider. It did take couple of reboots to opt out, but can be done.
Could this be a hint to Official Release this week?
Regards,
Well today is "Patch Tuesday". There may be an update for users who have 20H2 installed that preps the PC for the upcoming 21H1 release.
