Wouldn't recommend running production services on windows.

You have Windows Subsystem for Linux (WSL) which will allow you to run Ubuntu within Windows.

Or you have Docker for Windows which also utilises WSL in a similar manner.

So yes, although not a native Windows exe, it's perfectly possible.

Maybe but it doesn’t seem like a terribly good idea. All prior art for Lemmy, and most serious server stuff on the Internet, is on Linux. It would be a lot of effort and would result in a worse solution than the tools that already exist.

If you compiled from source maybe, but that's the point of docker, you can run docker containers anywhere

There are lots of docker deployment examples, and no reason it shouldn’t run in docker on windows. It supports Ubuntu containers. https://docs.docker.com/desktop/wsl/

I believe it can be, but what I've found in general with respect to my fediverse journey is that pretty much everything is built for Linux. If you want to use windows, you'll likely have to blaze a trail for yourself.

I had one windows PC in my server farm initially, but installed Linux after I realized most things I wanted to run really wanted me to be running Linux.

Everyone else here is saying it’s not recommended. I’d agree with that. But I’m super curious to hear whether we can, not whether we should! So, OP: I say give it a go and report back what problems you run in to!
