80% CPU usage by "NT Kernel and System" in Windows 8 Developer Preview

    General discussion

  • I've recently installed Windows 8 Developer Preview on my Desktop PC and I hear a lot of fan noise. I opened the Task Manager and found out that NT Kernel and System is using about 70% of the CPU. What should I do? What is NT Kernel and System?
