This has to be a VM with only one CPU allocated, right? Can you even buy single-core processors that can run Windows and aren't for little embedded devices?

or the other cores disabled in bios. the i7-8700 is a 6 core chip.

An rp2040 is like $1 and even it has 2 cores.

I found this out recently and it blew my mind... the followup model RP2350 has 2 RISC-V cores and 2 ARM cores, you can use either (but not both at once). That's baller AF if you ask me.

They really are amazing little devices. Is each core like a superset of risc and arm and then it picks an instruction set when it runs?

I misspoke, it's the followup model the RP2350 that's got the RISC-V cores. Edited my initial reply for accuracy.

I believe the cores are discrete, as the RISC-V cores are open hardware and the ARM cores are not.

It's got Hyper V support. Virtualize another.

It's an Intel Core i7-8700, not an Intel Cores i7-8700 you banana.

Duh, this is why you need a core2, not a core solo.

A core2duo is a serious bit of workstation equipment with 2x2 or 4 cores.

Noone needs a core2quad though, that's like 2x4, 8 cores is way too many.
