There's this[1] or are you looking for more functionality than it offers?

ARD is functionally the same as RDP on Windows, but if you're used to the speed of RDP, it can be painful to use ARD even on a fast network.

There aren't many things that Windows does better than Mac, but in my opinion, RDP is definitely one of them.
