uninstall win7 ultimate

will windows registration server automatically detect if I uninstall win7 on one machine and reinstall on another (ie, will it accept the license key on the new machine, or will I have to jump through hoops?)

MS Windows 7 Ultimate SP1 64-bit

Re you original question: My experience has been that sometimes MS will complain, but always after calling them and explaining the situation then all is in order. I have MS to be very flexible in this area. I would even say that MS has been customer-friendly in this regard.

The deactivation of old activation is done when you trade numbers during the robocall, as is the new activation.

It basically updates the hardware signature stored for that Product key..
