I was a original Beta and Alpha tester for Microsoft on Window 95 and 98...before they started charging to beta. I use now Windows XP Pro..I would not go back to Fat 32 hard NTFS drive runs smoother. The biggest problem you will have ....do you have enough memory and CPU power. Also your system won't crash as much with XP... If you ever want to edit video on your system of NTFS. But make sure you have a good defrag like norton.
