reinstalling windows do i have to worry about key?

I going to move my windows 7 key to another computer and do a clean install for my computer of windows 7 pro
im worried about the other computer
I have a family upgrade pack (3 pack) all 3 are used however I going to upgrade one computer to pro with a new install and key
so I would be only using 2 will this work? or will I have to call Microsoft?

to sum up I want to move a key from my family upgrade pack all 3 used but going to be 2 when I move windows to pro
or it upgrade keys like OEM tied to mobo?

Just activate it if it comes up. You can only have three active at a time. I'd have to guess I've reinstalled at least 50 times total and I've never had a problem activating. You may have to do the other two depending on when they were installed, but you shouldn't have issues.

what do you mean by "do the other two" just reactivate them? or reinstall?

just click the option to reactivate when it pops up. Windows 8 is a little more annoying than windows 7.
