Phil,
You are not very clear in your post what you mean, but retail versions are
allowed to be reinstalled on any system as long as the same Product Key is
not used on more than one system at a time.
The OEM versions can be reinstalled as many times as you want on the same
computer, but cannot be transferred to a completely different system.
