"To run rclone mount on Windows, you will need to download and install WinFsp" points to
http://www.secfs.net/winfsp/ which if you click the download button, which will download the old version

I've asked Bill about that...

@asdffdsa

perhaps the docs should point to https://github.com/billziss-gh/winfsp/releases/tag/v1.9

I'd rather not point to a specific version, but we could point to https://github.com/billziss-gh/winfsp/releases?
