I own an Acer Laptop and it comes bundled with Windows XP OEM version, meaning to say, I paid for the license key. When the laptop reaches the end of its product cycle or I decided to upgrade to a newer laptop with no operating system, to my horror I discovered that Windows XP refuses to accept my product key which I paid for together with my previous laptop, from my understanding, the specific key is tied down with the hardware (acer), likewise, a Windows OEM key meant for Dell will only works with dell machines, probably I am wrong. That is so unfair, I paid for the license, and shouldn’t I have the liberty to transfer it to another comp if I choose so?
There got to be a way to work this around.
