Basically, install Windows as you normally would, but when asked for Time and Currency format, select English (World) instead of your country.
Then let the installer do its thing. Eventually, you will see a window with an ice cream cone on the floor with the words “Something went wrong” and the error message “OOBEREGION.” This cryptic message means that the “out of box experience” (OOBE) didn't launch because it didn't know which region to launch.
Click Skip, though, and Windows will install just fine. You won't be prompted to buy Microsoft 365, you won't be prompted to pay for a OneDrive subscription, and your Start menu won't be cluttered with apps.
I had an issue switching away from Pop!, and it may have been a one off, but when I tried to install a different distro, and it wound up screwing up my boot partition to the point the easiest thing was just to run a live distro, pop open parted, and wipe from there before I could install a different distro.
Mostly mentioning it because it was annoying to figure out and remedy - the remedy was annoying because I only had one flash drive so I had to wipe what I wanted to install, and just wasting time regarding that.
