as you can see on the FreeSurfer download page, you need
either a linux or macOS system to run FreeSurfer natively
There are several ways to tackle your problem:
1. get a linux or macOS machine
2. run FreeSurfer within a virtual machine on your windows host, e.g.
3. run FreeSurfer within a docker on your windows host, e.g.
which also comes with amazing additional software such as ANTS and mindboggle
4. apparently it’s also possible to run FreeSurfer on windows 10 these days, pls check
However, I assume most peeps would recommend running FreeSurfer within a system which
was also used for development and testing.
