I think it actually works on Windows/powershell for now. We can't guarantee it because we can't test it, but we have a windows user who is always submitting fixes for windows
I tried it out and I couldn't really figure a way to `atuin init` on Powershell, as it requires one of the supported shells as a parameter.
I've also seen a couple of PRs such as [1] that consider Windows support a dead-end as of 2021, so I assumed it to be a dead-end as well. Maybe this user is on WSL? That'd seemingly work as it can get bash/zsh or anything running there.
