    How does the problem manifest:
    svchost.exe uses 100% of one core
    Restart of system hangs (putting the system into standby and resuming it resolves the hang)

    How did I debug it:
    1. Process Explorer (hxxp://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) to identify process and thread id
    2. Start Visual Studio
    3. Attach debugger to process with the process id from 1
    4. Break all
    5. Load symbols from MS symbol server
    6. Select the thread with the thread id from 1
    7. The last function in the stack trace is something like GetProcessSnapShot

    Solution:
    1. Go to services
    2. Change the startup value of the Superfetch service to Manual
    3. Reboot
