I asked Dell about Win11 on Latitude E5470 and the reply was "Microsoft doesn't provide driver support" … "but many users report it works anyway," I decided to install Windoze 10.

Of the three installations above, the first two meet the v2 "specification", but
not the third. In all likelihood, M$ does an equivalent check to what is shown
resulting above from Trixie, and below from openSUSE Leap, to see whether specific
CPU features are available. Leap 16.0 due in October requires v2 as a minimum,
while SUSE 16 according to the following URL will require v3.
I imagine Win11's requirements are different from *SUSE's, but the idea of
requiring specific CPU features is not. Whether any i5s would fail to meet v2 I
have doubts, as I believe the first post-Core2Duo/Core2Quad "Core" (e.g. i5-xxx)
CPUs from Intel provide the minimum features constituting v2, though it could be
i5-2xxx or even i5-3xxx. The Pentium and Celeron chips in the i3/5/7-4xxx series
do not meet v3, while the 3/5/7 do. Maybe for Win11 the minimum is stricter than v2.

The i5 host hp750 would qualify to run Leap 16, but the Athlon X2 host k9msi now
running Leap 15.6 won't be able to upgrade to 16, or install it afresh. This kind
of limitation looms as a potential in other distros to come, such as Forky,
somewhat like Trixie shed 32bit support. :(
