Second question, thought it beneficial to set up a second thread to avoid confusion. I'm going to be running some software which I'm sure with cause me conflicts. Pro music software often doesnt seem to like my photo software and my dvd player, so I'd like to try and separate them, if you get me. On my old pc I used partition magic and created a dual boot system. Before I try anything like that, is there any way I can set up user accounts so that one user ID has one set of programs and another ID another set, thus running I would presume, different registries? Someone told me you can do this in XP Pro, but for the life of me I cant see how? If I have to go the dual boot system whats a good peice of software that wont destroy hard drives and is reliable? Preferably fast and easy to set up also.
