  • Make a xperf trace to see the cause. Install the WPT (http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt-en-us.aspx), open a CMD prompt with admin rights and type this:

    xperf -on latency+ReferenceSet -stackwalk profile+VirtualAlloc+VirtualFree -buffersize 1024 -MaxFile 512 -FileMode Circular && timeout -1 && xperf -d highCPUUsageMemTracing.etl

    after you captured 30s of the cpu usage, go back to CMD prompt and press a key to stop the logging. Now compress the highCPUUsageMemTracing.etl as 7z (LZMA2, ULTRA) to reduce the size. Upload this file to your SkyDrive or Dropbox and post a link here.
