Hi, I'm Currently running "Windows 8.1 Pro Preview, Evaluation copy build 9431", Complete with it's 2 hour Restarts, I'm unable to afford Windows 8.1 Pro or Windows 7 Home Premium at the moment and I was wondering if I could run a copy of Windows XP without Licence Key now that support has ended and M$ are likely not making any more $ From it. if I can then I have a Disk for XP Media Centre Edition 2005 From a old Emachines computer I had a few years ago and don't have any more after 2 HDD Failures from Virus in the Motherboard or something. if a Key is needed, my mom's old computer that's still around got Home Edition, not sure if the HDD is IDE/PATA or SATA but if it's SATA then maybe I could put it in my computer and use the Product key on her computer to reactivate it or something? another option is to find/make a Windows 7 Home Premium 64 Bit Disc as I have the HDD from my old Laptop installed I would just need to get it to work with my computer and maybe running a repair or something from a disc would make it work on the Motherboard.
