Windows product keys

so i built a new pc for my dad for work, and so i cloned his hard drive onto his new ssd, it is now months later and i am planning on using the old hard drive in the old computer, what will happen if both copies of windows are being used at once?

As far as I know that is (at the very least) not allowed, and possibly will cause one or both to deactivate as a result.

noithing exactly. it will just ask you to activate the license because most licenses are bound to your motherboard so when you boot a pc off the drive it will detect new hardware and just ask you to reactivate windows. i built a new pc a while ago and did this exact thing and it just told me to activate windows on the new pc
