A static IP effectively means your computer will always be found at
the same address, so anyone on the network can reliably find your
computer when it is on and connected.

No, just that the remote controlling person wanted to use it for
something, no different from a remote controlling person using Windows
Explorer to copy files does not imply any vulnerability Windows
Explorer.  The vulnerability lies in how/where the remote controlling
person gained access to do the remote controlling in the first place.
That part is still a mystery.

I would check that your firewall is enabled and active, and if you are
not knowledgeable enough yourself, find someone who is to examine the
firewall rules for openings that should not be present as well as scan
the entire computer with an updated malware scanner.
