how this is done: process and thread have their own register set?

Hi,
I come across this question: each process and thread has its own
register set, at least program counter register. But one processor has
only one PC register, right? If this is the case, then how can
multiple processes have their own PC register?

Do they have to swap out? But how about thread?
