Reserve windows package names

[leipert]

Regarding a bug that appeared in the rust community (rust-lang/crates.io#695 and http://sasheldon.com/blog/2017/05/07/how-i-broke-cargo-for-windows/), should we reserve some package names to mitigate problems?

May be relevant:
npm/policies#36
npm/npm#10833
