If you're forced to use Windows, and you want to browse the internet behind tor you can use the links2 windows binary,

and chain it to the tor expert bundle binary.  I just tried this out and it worked fine.

endtorrc works with this setup but you have to comment out the Sandbox variable.
and place the torrc, torrc-defaults, geoip, and geoip6 files in the directory C:\Users\user\AppData\Roaming\tor\
