I've just built a computer for a mate of mine using Windows 7 for the OS, which is my first time using that software. My problem is, is that when I partition the hard disk into 'C' and 'D' (C for the OS, D for all the rest) all the preloaded Microsoft games (Cards etc) become non fuctional. I have tried all ways of accessing them, both directly and indirectly, and no luck. However, they do work if I eliminate the 'D' partition and have everything installed on a single partition. What could be causing this? Tom.
