Symptoms

Assume that you add or update some performance counters on a computer that is running Windows 7 or Windows Server 2008 R2. In this situation, changes to the performance counters are not updated for at least 15 minutes when you use Windows Management Instrumentation (WMI) to query performance counter values. When this issue occurs, you cannot query the expected updated values from the performance counters.

Cause

This issue occurs because the performance counter WMI provider keeps a cache which is refreshed every 15 minutes. If a query is issued within 15 minutes after some performance counters are updated, the refresh timer starts to count from 0 again. Therefore, changes to the performance counters may never be updated if a query is issued every "T" minutes and "T" is less than 15.

Workaround

To work around this issue, restart the computer.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More information

As a simple example, use Wbemtest.exe to run the following query:
select * from Meta_Class where __Class like 'win32_Perf%spooler%'

After you run the query, change the state of the spooler by using the following command at the command prompt:
net stop spooler

Then, immediately re-execute the previous query in Wbemtest.exe. The query results do not change before you apply this hotfix.
