Vista - high cpu usage using wmi

I have written an application that starts a ManagementEven****cher and uses
WMI. The application takes around 0-1% CPU in XP whereas in Vista CPU usage
is 40% continuously. Is there a fix?

You are posting from the future, please adjust your time&date settings.
I never read posts from people who try to get on top of the list this way.

Well, your .Net program runs on a thread. So, set the thread's processing
priority.

System.Threading.Thread.CurrentThread.Priority = High, Normal,
BelowNormal -- enums.

You can look it up use the .NET IDE Help or use Google.

You should post to a MS-Public-dotnet NG.

Hi Mr Arnold, the program runs fine on Windows XP. I saw that the CPU is
used by wmiprvse.exe which is not the same process as the program. So
System.Threading.Thread.CurrentThread.Priority on the program will not
affect wmiprvse's priority. I have manually set wmiprvse.exe's priority to
low but no luck, the same 40-50% use.

This problem doesn't occur in XP, and the program and wmiprvse.exe both take
less than 1% CPU on the average. So, it is a Vista issue.

Your further suggestions are appreciated.
Thanks.

You may be able to look at the code for this solution and pillage and
plunder something together that you could use, non UI. It's a shot.
