I wanted to use it as well on windows the other day.
Because I wanted to migrate a mssql database to PostgreSQL. However AFAIR there were no builds I could find and from what I read in the issues it is quite discouraging, a pity

I recommend the Docker image over downloading and running it locally anyways tbh -- you can just prune Docker images to remove stuff without needing to remember to delete it, and you don't have to copy it to your bin dir in PATH.
First is writing your own tool with the connector libraries working fine on windows sql server in the lang of your choice which is great if you have to do transformation on the data for whatever reason while you are importing - the second is dumping from mssql to csv, then loading it in, which is honestly the KISS way to go as long as that is all you need to do.
Best of luck!
