If you have to reinstall Windows 7, you should not have any problems re-activating and not have to use the last remaining activation (he says hopefully and with fingers crossed.) When you originally activated that copy of Windows 7 by entering the 25-digit Product Key, a unique "hardware hash" was created based on the hardware installed on that specific computer. The hardware hash takes into account the various manufacturers, hardware serial numbers, amount of RAM installed, etc. As long as the hardware hash is recognized as being the same as originally created, re-activation should proceed without a hitch. If by some chance it doesn't re-activate, you could also contact Microsoft directly via telephone support and provide them the 3 pack details.
