The reason why the windows-sys (and below the windows-targets) crate are so beefy is that they are basically a bunch of binary blobs that are needed to link stuff together due to how import libs work on Windows. https://kennykerr.ca/rust-getting-started/understanding-windows-targets.html https://kennykerr.ca/rust-getting-started/understanding-wind... In theory that would not be necessary any more on more modern rustc versions, but if you want to target rustc < 1.70 you still need that.
