Well, Windows 7 (Pro and above) will run M$ "Virtual PC". Addfitionally, they offer , "XP Mode" which is a licensed copy of Win XP Pro, SP-3...! (These are both free with Windows validation)! You just install them both, and run XP to your hearts content. You can even install XP programs in the virtual machine. That's the point of the whole endeavor , so please accept my apologies for stating the obvious.So, you can not only make it look like XP, it IS XP..! However, in another post, you mention having to install XP, to run a particular game. You might be able to run this inside "XP Mode" also. I don't however know, if any speed would be lost within the virtual environment. That said, Win 7 Pro, is only 30 dollars* more than "Windows 7 Home Premium", and that sounds like a strong bargaining position to me! (*) The quoted $30.00 dollar difference is with OEM copies, IDK about the retail version(s).
