So I purchased an HP latop right when Windows 7 was coming out and the HP laptop had Windows Vista when I bought it but I was sent a free upgrade to Windows 7 Ultimate by HP during the time when they were selling laptops with Vista and sending free upgrades.
So what I want to know since the fan stopped working some time ago, (cooling it with a small fan from Walmart sending air around and inside it somewhat) on the HP laptop I purchased and recieved the free upgrade. If I return the HP laptop to factory settings (did a complete backup when purchased) and put Vista back on it, can I use my Windows 7 Ultimate disk in a newly purchased laptop since it will still only be on one laptop since I am returning the old one to Vista?
And do I have to uninstall Windows 7 Ultimate with the Upgrade disk so it knows it's no longer on that computer. In other words are they linked by some type of serial number on my HP laptop that only allows me to install the Windows Upgrade disk on that specific machine?
Hope I made sense out of that situation
