Just performed in place upgrade on unsupported machine, 24H2 -> 25H2

@(set '(=)||' <# lean and mean cmd / powershell hybrid #> @'

::# Get 11 on 'unsupported' PC via Windows Update or mounted ISO (no patching needed)
::# if WU is stuck use windows_update_refresh.bat; Beta/Dev/Canary needs OfflineInsiderEnroll
::# V13: skip 2nd tpm check on Canary iso; no Server label; future proofing; tested with 26010 iso, wu and wu repair version
