    You can use the harddrive, but the OS won't transfer. As said, you will likely have to reinstall it and call Microsoft to validate it. If you tell them what you want it for I'm sure they won't care to revalidate it for you. If you have the original install disc you can try just reinstsalling it to see if it works, but you'll probably have to call Microsoft. If it's a new enough computer you might just buy a copy of Windows 7 and save him the horror of having to use Vista and save your self the trouble installing it.

    yes and no.

    if the OS is OEM and bios-locked, then no. OEM is licensed to stay with the computer.

    I don't think it would be legal to do this given microsoft's licenses.

    the least expensive route is 7 home premium full retail at $180

    pro and ult have the capability of xp mode for running xp apps in a virtual machine.

    even if you were to use the oem you would have to do os repair or format,and there would be driver differences since all the hw is different (cpu, mobo, hd, RAM). os may throw a fit.

    download all your drivers first!

    and don't do a download version of windows! get the box.

    HDD, yes, OS, no. assuming it's a generic version, it's bound to the motherboard it's originally installed on.

    For HDD, you can just unplug it from your old, make sure it's standard 3"5 size and you have enough bays for that size, then plug a SATA cable from your Mobo into the HDD, then it's good to go.

    Good luck!

    it particularly is super for the hot buiders and in case you're actually not wanting a super computer and might cope with some artwork arounds and bugs you may run into I say super. you likely will could call in a reactivate the homestead windows do to the hot hardware. sturdy success!

    You can, but it might have some consequences, like having to call Microsoft to validate your install.

    No! Why bother doing that when you can buy a new one instead?
