So far a hot mess.  I spotted this forum after going to Friends of DC.  While new a couple of things.  1. MS was not ready heck they even broke the HealthCheck app. I tried all the other apps and found 2 that were ok. Wise Software has one which is slow and not correct - Check it.  I prefer Ready & Sun Valley which is more polished but still is incorrect.  But it does run WhyNotWin11 inside the program ( Get 2nd Opinion).  I have a Frankenstein PC with an i5 2400, but 9 TB of drives most if not all GPT, but the apps say that on MBR is installed.  I have 16gig memory but the apps show not passed.  I fear it will be weeks if not months till we get the real answers.  And lastly, I am on the Insider track and MS Insider Mgt stated over a week ago that IF you had provided feedback via Feedback Hub, etc then you would get a Windows 11 update next week which has passed.  I am in no hurry to buy a PC, but if forced to just do an MB transplant with a newer CPU for a few hundred dollars. Should be interesting.  But these MS folks seemed to have dropped a lot of balls so far.
