Greetings all. When I open a folder which contains video files Explorer hoggs 100% of the CPU. You can hear the HDD spinning away. I had this problem before and was told to alter a value within the registry accociated with video files and I cannot for the life of me find that solution. Any help on this matter will be greatly appreaciated. Kind regards. Rad

There's a bug in XP that can cause your CPU to go to 100% and other operations (such as copying files, network connections or streaming audio/video) to suffer degraded performance when you right click a file or folder. Want to know why it happens and how you can work around it?

Thank you John. Allready tried those suggestions via the links. Still have the same problem. I seem to recall that I had to change rather than delete a registry setting, but for the life of me cannot remember or find the appropiate link. Thank you again for the input. Rad
