I installed 2k3 on my brand new laptop. I found certified drivers for all hardware. What I had was a very fast and stable OS, and I only found one thing, but that made me go back to WinXpPro: When ever I start a movie, using WMP9, it would take a long time to start playing. This I could live with. But the next time I wanted to start the program, nothing happened, exept explorer.exe went to 100% CPU usage and I had to reboot.
