I've got windows 7 installed on my pc, and it seems that there are issues with Windows 7. Many problems concerning drivers have not been solved. My scanner and my webcam doesn't work on windows 7, but it works on winXP. The driver doesn't work on Windows 7 since Microsoft doesn't even want to develop them.

Also, when my pc shuts down, sometimes it gives me a message that some programme are causing problem and it doesn't shut down automatically, so it wait for me for my approval in order to do force shutdown. It's really stupid system, since the other day my pc was on for several hours because it waited for me to do force shut down.
