On the other hand if the work is done on Windows it's much better to learn that platform than pining for something else.

Go with whatever is platform specific, and available out of the box. Avoid complex configuration packages just to get the specific interface flavour to the computational substrate you would prefer to use privately.

The reason is, if there is specific computational platform that the employer is using, you are much more helpfull to all around you if you operate with the vanilla settings rather than try to find something more special.

Privately try to find the best methods that work for you, in public, collaborating, try to find the most simple and straighforward method of contributing. Simple in this case does not mean a kludge, but it may mean a few extra lines of code or configuration here and there.
