It's an ARM CPU. It requires ARM Windows, which is
probably a simple kiosk system for running tablet trinket
apps. There would be no way to adapt Win32 to that
without a whole set of system files to intercept calls,
with the Win32 software in some kind of sandbox.
Something like WINE. But even WINE is working on the
same CPU. It's just translating function calls to Linux
libraries, not translating CPU instructions.
It needs something like Apple's Rosetta
which they used when they went from PPC -> Intel
or Rosetta 2 when they went from Intel -> ARM

drive having a large .WIM (Windows image) file, so I'm wondering whether
the second partition isn't being seen?

You have to have duplicates of all the libaries and frameworks, too. All of which need testing when you make a new OS version. Which is why Apple doesn't keep Rosetta around for ever, especially as you also need duplicates of all the libaries and frameworks for 32-bit and 64-bit. It's prolly why Apple dropped 32-bit support in going from Mojave to Catalina (which I'm now on), as
they knew they had the transition to ARM coming up. Not that the loss of 32-bit app support affected me, as the only remaining one I had was the Usenet
client I was running. But then lo and behold, up pops someone and writes a new
macOS Usenet client from the ground up. No need even to mess with Thunderbird.

Arms don't use microcode. However you can write an emulator in Arm instructions, which Microsoft have done.

Well then, it's handy that Microsoft have done all that, and you can buy laptops
and desktops with Windows on Arm, including x86 emulation, right now.

The preferred high-performance emulation strategy is object code
translation, usually managed dynamically, like “throw-away compilation”. When applied to loops and other frequently recurring code, performance can approach native host performance.

to turn a RISC core into a CISC machine.
But a quad core i7 ot i8 has massive pipelining as well.
And that needs to be on chip.

can exceed this performance, since the object code translation is done

code compilers.
And RISC architectures are quite amenable to aggressive pipelining and
multiple instruction dispatch—something that gets quite hairy with the
x86
architecture (but of course Intel is not afraid of hairyness ;-).
On of the nice features of 32 bit ARM at least as far as human
programmers of earlier ARMs, was conditional instructions, which
eliminated the need for pipeline stalling branches around small sections
of code.
However, with more sophisticated processors it prevents the branch
predictor eliminating the instructions entirely from the pipeline (the
vast majority of the time), and instead evaluates to NOPS taking up
execution slots. It also makes the go faster stripes of superscalar and
out of order execution more tricky and less efficient.
With a code translator the conditional 32 bit instructions can be turned
into 64 bit code sections surrounded by small branches, making it look
like horrible spaghetti code for humans (if anyone still eyeballs
AArch64), but far more optimal to modern CPUs.

Actually Win-11 fits on a 32 GB SD, but not much room for big programs!
A 1TB SanDisk external SSD is noticeably faster, though. Transfer speed
is then limited by the RPi-400 USB-3 port.
Yes, I have Win-11/64/ARM running /directly/ on an RPi-400. It runs
some x86 programs too. There's no support for the RPi built-in Wi-Fi so it's either an external adapter (I used a Wi-Fi to Ethernet, but a slow
one!) or a direct LAN connection.

When a 16G Pi5 comes out, I'd be interested in what its cost would be
with an NVME adapter. But suspect that'll be well into next year. I
reckon from what I've read that the performance would be pretty close to
my 16G I5 NUC with NVME SSD - and I suspect it would be a lot cheaper.
And I suspect it would use less power.

The "credit-card" profile of the PIs has always been
a big plus. The (relatively) low power required has
also been a plus. The low(er) PRICE has always been
a plus. As I said, they fill a *niche* quite nicely.
But their AMBITIONS seem to aim towards leaving that

Not really. If they are competitive they will win, If not, they wont.
Stop thinking in ideological terms and look to why people buy what they
buy.
If someone brought out a PI that costs the same as an intel MoBo, and
was inferior in performance, no one would buy it.
If they brought out a PICO that cost more than an equivalent Arduino,
no one would buy it,
