    Clean install of win8 pro on half of a laptop (other is XP).
    Disk space is 24G, processor 1.6mh,1GB ram. 32 bit.
    Task mgr reported CPU uasge of 10% until the addition of windows media centr pack. Now usage is
    70 - 90%. Culprit is system interrupts which uses 60%. Suggestions?

    Hmm I assume you meant 1.6GHz for your CPU right? You could try looking at the issue with http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx and see if it sheds more light onto the "culprit".

    Also have you been using any new attached devices recently? USB flash disk, webcam, external hard drive?
