If some third-party article or blog post has instructions that don't work, you should probably contact the author of that post.
That said, building V8 on Windows is easy, just follow the instructions on v8.dev. In short: get depot_tools and put them in the path; fetch v8; cd v8; gclient sync; gn gen out\my_dir and adapt build parameters as desired; ninja -C out\my_dir d8 In other news, I can confirm that gm.py currently doesn't work on Windows. I'll fix it. That'll make the last two steps (gn gen + ninja -C) even more convenient.
