Question – Updated my last Win 10 Pro to Win 11 Pro 21H2 — could use some coaching now . .

I would have just done it straight to 25H2. What registry hack? You just do “setup /product server” from an admin command prompt after changing to the ISO drive letter and off it will go.

Actually, I’d read about that here in the forums a while ago, but I had the instructions from last year involving the registry key for “MoSetup”, and just did it that way.

When I downloaded the ISO file initially, I only guessed that it would be the up-to-date build. So, this morning, I decided to take action toward moving it to build 25H2. The other two systems, all same processor generation and Z170 chipset deployment, have updated to 25H2 already. So I did a little reading, poked around in “11 Forums” and elsewhere, then disabled my MalwareBytes AV program and ran the 25H2 ISO the same way I had installed Win 11 initially (giving me 21H2).

I’m done with this now. All is good! I had to “remember” some details I’d encountered last summer with the other two systems. For instance, given certain drivers and hardware, I had to turn off “core isolation”.

I see that I could’ve avoided starting this thread, but it was the “snag” I mentioned, only to realize I hadn’t disabled my AV program.

Looking a little further, it appears there’s a 26H1 build in the wings, but it’s only intended for ARM processors.

I’m looking back over 40 years now. I wish I hadn’t become so OCD and obsessed with the microcomputer technology, or that I hadn’t done somersaults to keep building my own systems as I did. I’d be a completely different person now. I might even have gotten laid more in the 90s.

BUT! Like Ray Lucca (Tony Denison) tells the FBI Feds (Dennis Farina) in the late 80s crime drama “Crime Story” — “I’m back. I’m bad. I’m on top! You wing-tip bozos don’ have nuthin’ on me!”

Just wondering how long my mind is going to stay this sharp . . . or whatever that means — as sharp as it still is . . .
