No. You typically can't free memory back to Windows (or many other OSes).

Yes and no. It makes more memory available, but only memory that would
have been made available in any case if you had tried to use it. R calls
the garbage collector before requesting more memory from the operating
system and before running out of memory.

You can't do anything else to make more memory available, only to use
less.
