I couldn't find the 3rd box of Windows 7 Ultimate that I bought, so I tried using the 2nd box which I already used for activating Win 7 on my Notebook computer...

Strangely, it says Activation successful... (on the desktop computer) and my Win 7 Ultimate is not a family pack... so how come it can be activated on two PCs?

Windows can be activated more than once. Even when that fails you can still call up Microsoft and they can give you a number to type in by activating over the phone. The main idea is that people will have to re-install their computer and it would be a PR nightmare to only allow you to install Windows once. Maybe I upgraded to a new computer and trashed my old one. – Daisetsu Apr 1 '11 at 21:12
Give it a few days, and one of them will start to consider itself nonlegit. – Tarnay Kálmán Apr 1 '11 at 21:15
are you sure...? you are talking as if it will recheck? – 太極者無極而生 Apr 3 '11 at 3:14

Probably to save money on support calls when a person has to do a reinstall from scratch. When we purchased a single license of Windows 7 through our Volume License agreement, we got a MAK that would activate 50 copies of Windows 7.

Just cause it works doesn't make it legit.

As long as he owns 3 copies hes fine. Microsoft doesn't care so much about which copies are activated as much as if the users owns enough licenses. – Jeff F. Apr 1 '11 at 21:01
I wasn't intending to make the case that he was or wasn't acting improper. My point is only that Microsoft does allow extra activations in different circumstances. – emgee Apr 1 '11 at 21:03
