Perfect! Thank you! 😃

That's the point. I would gladly accept to use the registry tweak. Thank you. But I can't upgrade to the latest Windows 10 general availability channel using Media Creator since the destination target will be LTSB 2016. So the first issue to access a Windows 10 - 'Redstone 1' v. 14393-1607 ISO is unfortunately the same.

Thank you!... Well, running Windows 10 with that N3540 CPU is a big word. 😄

Thank you for the clarifications. So if the target for a current Windows 8.1 Pro would be a LTSB 2016 v. 1607, I would need the Windows 10 1607 Build 14393 Anniversary Update - 'Redstone 1' to be installed preliminarly. Which source would you suggest to download that untouched old ISO? Eventually I would like to check the SHAs.

Probably it was 8.0. From Microsoft source: "In-place upgrade from Windows 7, Windows 8.1, or Windows 10 General Availability Channel to Windows 10 LTSC isn't supported. Windows 10 LTSC 2015 didn't block this in-place upgrade path. This issue was corrected in the Windows 10 LTSC 2016 release, which only allows data-only and clean install options." (In fact, there are even Youtube videos that document a registry hack on Windows 10 'general' in order to install a LTSC release). Therefore I am not sure that makes sense upgrading Windows 8.1 to 21H2 or earlier, i.e. a 'Windows 10 General Availability Channel' release because this procedure would not allow to upgrade further to any LTSB 2016 or LTSCs, at least with in-place procedure that your post#1 implied. Any explanation why it should work, please?

Hi Everyone! Running a trusty Lenovo G50-30. Thinking how could be keep alive since Windows 8.1 is EOL. Back in the day, had some experince with Macintosh; now only Windows OS.

Hi Everyone and @Aaron44126! Are you sure that Windows 8.1 can be upgraded to Windows 10 LTSB 2015 (before eventually migrating to LTSC edition...)? It is my understanding that upgrade path was limited to Windows 8.
