Emacs is available on Windows so just install it and then clone the Spacemacs GitHub repository to C:\Users\<username>\AppData\Roaming\ and rename it to .emacs.d\ As i remember, though, i think it was slower than on Linux, but might be something else was going on with my setup back then.

I've also tried running it from WSL. Running it in cli mode was sufficient for me, but i was also able to use GUI mode by installing an X Server (VcXsrv i think) on Windows and making WSL work with that. It makes sense to use it from WSL, if you do your development work there as well. Also, it was before WSL 2, so i don't know if anything's changed now.
