Why is my CPU running at 100 percent, when only three windows are open?!

Question:

Windows XP: Why is my CPU running at 100 percent, when only three windows are open?!


I run Windows XP (Home Edition)on my system and frequently find that the number of processes running can be as high as 63, with the CPU usage rising to 100 percent and a commit charge of 943M/2313M. I should add that this happens with only two or three windows open but minimized.

This completely takes over my PC and virtually brings it to a non-useful condition. Can anyone please tell me what can be done to help me safely bring the amount of processes down as I don't believe that all 63 are needed? Many thanks and kind regards.
