Explorer.exe / Windows XP

When I have many (9+) explorer windows open at the same time, windows xp starts to behave very strange. After a while it won't create any more windows and I have to close all of my explorer windows. Needs urgent update to fix this issue plz.

Apple Itunes

I installed itunes (cause I have an iphone) and when the installation was complete, without warning, the installationprogram restarted my computer, forcing me to close a lot of programs that was running. Superannoying!
