    The Desktop Window Manager is experiencing heavy resource contention.
         Reason         :             CPU resources are over-utilised.
    Diagnosis     :             A sharp degradation in Desktop Window Manager responsiveness was observed.

    This report has me puzzled on a Windows 8.1 computer on a good specification computer. Please make suggestions for investigating this issue.

    TIA, Gerry

  • Hi,

    Did you make any changes on the computer before the issue happen?

    Please install the WPT:


    Then, open a cmd prompt with admin rights and run this command for 30s:

    xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl

    Press any key to stop logging. Then upload the file after zipped to the SkyDrive or similar network drive, and post a shared link here for further research.

    Also, please check the following location to see if the Dump file exists.


    If it exists, please upload the dump files so that we can help you analyze them.
