WMI Provider Host excessive CPU

ktoerne - yes I did manage to resolve it but more by luck than anything. I tried some other forums but no one seemed to come up with an answer as to how you could track the cause of the problem down. I really not sure it is possible. However I discovered purely by accident that it was Garmin Connect that was causing the problem on my machine. I believe the issue is basically caused by an application asking for some windows instrumentation data. I was running Garmin Connect to upload data from my Garmin Edge 25 cycling computer to Garmin's web site and when the process was finished (only takes about 30 seconds each time) I would click close on the Connect application and it would go away but continue running with an icon in the little box that you get when you click on the upwards pointing arrow on the right of the task bar. I right clicked this and it gave me the option to "Exit" Garmin Connect and instantly the problem went away as the app closed down completely. I have reported the problem to Garmin but they haven't done anything about it.

So all I can suggest is that you bring up task manager and then selectively try completely closing any non Windows system app you find in that list on the bottom right of the screen and see which one is causing your problem - assuming you're not running Garmin Connect of course - if you are then you probably have an easy answer. 

Good luck.
