GoPro Studio Importer causing High CPU

Ping back to http://blog.notmyfault.ch/?p=427

Lately I have noticed my laptop experiencing the following symptoms:
- Running Hot
- CPU constantly at >50%
- Slow to load things

After using Process Explorer (Sysinternals) I could see this was related to a WMI Provider Host (WmiPrvSE.exe) running as NETWORK SERVICE. The strange thing is the performance profile as it constantly spikes for a second, drops, then spikes back for a second, drops... repeat. Clearly indicating that there is a query being run at very frequent intervals as evident by this chart.



I found it difficult to track down the culprit causing the WMI queries, but I knew the problem was still evident after a reboot so I started checking my tray icons and start up applications. By process of elimination I found that closing the GoPro Studio Importer the problem went away.

The importer is run from the executable: C:\Program Files (x86)\GoPro\Tools\Importer\GoPro Importer.exe
GoPro Studio version: 2.5.4.404

To validate this I launched the executable and the problem returned.

I haven't found any settings in GoPro Studio to prevent the importer launching at startup, so I simply went to the Startup tab in taskmgr and disabled it from there.


Props to the blog http://blog.notmyfault.ch/?p=427 which helped to clarify my findings.

  1. You are right; I made the same findings and indeed deactivated the automatic startup to bypass the problem.

  2. Hi. I had exactly this problem and it was driving me crazy. I started trying to debug WMI and very quickly ran into lots of dead ends as there simply is no transparency with the service. I have 20 years experience working with Windows NT derivatives and knew that it wasn't me being a numpty. As you did, I noticed that the problem didn't start until I logged on, so I proceeded to uninstall the programs listed in my startup programs (using msinfo32) with a reboot after every uninstall (to ensure a clean startup). Eventually I got to the GoPro studio and the problem was sorted. Unlike you, I have uninstalled, rather than stopped the program. But now I know what it is, I can reinstall it and stop the importer running at login.

    Here are some tags, which will enable others to find this post and hopefully spend less time on this issue that I have: WmiPrvSE.exe WMI Provider host High CPU NETWORK SERVICE
