Daylight Saving: What do I need to do when Daylight Saving starts or ends?

For Windows XP Media Center Edition

If you have a Windows XP PC running Windows Media Center then the changeover should go off without a hitch as the computer should update your timezone without any user intervention. The best thing to do on the Sunday morning is just check that the time is correct after the change and check a couple of your recordings to ensure they are still showing the correct start time and duration, or end time.
