Win32_Processor (WMI class) and Vista

Question

 

Hi,

 

It appears that some functionalities of the Win32_Processor class doesn't work with Vista.

I mean, I don't understand why the property LoadPercentage send back 'None' whereas all is OK with Windows XP.

 

Perhaps it misses a package on my computer of sthing like that? I don't think because some properties works...

 

Thx for your answers.

Answer 1

 

I mean: (Python script)

 

objProc = GetObject("winmgmts:root\cimv2:Win32_Processor='cpu0'")

objProc.name is OK

objProc.LoadPercentage returns None

 

However the following link http://msdn2.microsoft.com/en-US/library/aa394373.aspx claims it should work with Vista...

Answer 2

 

I have no problem executing such code in C# but you might try the same and run it as administrator and see if that makes a diff.

 

Does other wmi properties for that win32_processor have correct values when running your script?

 

Answer 3

Closed as no repro.

Answer 4

I am trying the Same method but load percentage is showing null.

I have checked it on Vista as well as WinPE2.1

Is there any other method we can implement?

 

Answer 5

Same here, Win32_Processor.LoadPercentage is null when being pulled remotely .

Local performance is showing up.

All other options are there, both locally and remotely.

Target servers - Windows 2008 x64, Windows 2008 x64 R2.
Source servers - Windows 7 x86, Windows 2003 R2.

Note: everything works if Source is a local admin on Target, but I want it to work with WMI and DCOM permissions only. Possible?

Answer 6

what is a 'repro'?

Answer 7

I am having the same problem.

When pulling the LoadPercentage from Win32_Processor it returns null.

When i am looking inside the WMI (wbemtest) the Instance CPU0 is also returning null at LoadPercentage. In this case i am running Windows 7 Professional 64-Bit. This is only on my PC. When i look at a testing machine it returns a valid value between 0 and 100.

This is a business machine at my work. and whe are using monitoring software to monitor the CPU usage and disk usage of all machines at my work and at customer sites.

Edit:

Oké i fixed the issue with the folowing command:

lodctr /r
