How can I use this tool on Windows

[ronenfe]

I'm running the AWS CLI in windows command prompt. How can I download and use this tool?

[ronenfe]

Ok, I had to first install VS Build tools C++ and Rust for windows.

Installation failed with following errors:

Hi, thanks for your interest in using coldsnap. Unfortunately, this tool only supports unix based operating systems (as seen in the error you're hitting trying to compile on Windows). I would assume that the Windows Subsystem for Linux (WSL) would be enough to run this, but I have not tested it

[rlights]

Confirming it runs fine in WSL (Ubuntu), however on download I was getting around 10% failed blocks until I specified the region, not sure if this is expected behaviour.
For anyone else finding this in future: I had to remove the default rust installation populated in my wsl (sudo apt-get remove rustc) and install the latest with rustup (curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh)
Not sure if this will apply to everyone since this is an older wsl instance.

Perhaps it'd be worth at least mentioning in the readme that this doesn't operate on windows since rust is intended to be cross platform.
