I would like to claim this issue. I'm currently reading through the relevant python docs, linked threads, and the src. If anyone has any suggestions at where to direct my attention, it would be greatly appreciated.

Hello, I have rough steps but I don't have detailed descriptions.

1. Try to change memmap2 in stdlib/Cargo.toml to cover windows.
2. The major difference of windows version is constructor. We can start with constructor and try to solve other stuff later.
3. Run test_mmap to check how it is going. cargo run Lib/test/test_mmap.py. You don't need to make everything working for single PR.

@killme2008 do you have any advice?

@youknowone I don't have more advice, it's a good guide to start.
