The PdhEnumObjects function used together with the bRefresh parameter does not function correctly in Windows 7 or in Windows Server 2008 R2

View products that this article applies to.

Symptoms

Assume that you have an application that uses the PdhEnumObjects function together with the bRefresh=TRUE parameter to retrieve the list of available counters on a computer. In this situation, the PdhEnumObjects function does not refresh the list of performance objects if the application is running on a Windows 7 or Windows Server 2008 R2-based computer. For example, if you run a service that installs new performance counters in the operating system when the application is running, the application does not include the newly added counters in the list.

Note If you restart the application, the newly added counters are included correctly in the list.

Windows 7 and Windows Server 2008 R2 file information notes

The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

Version	Product	Milestone	Service branch
6.1.760 0.16xxx	Windows 7 and Windows Server 2008 R2	RTM	GDR
6.1.760 0.21xxx	Windows 7 and Windows Server 2008 R2	RTM	LDR
6.1.760 1.17xxx	Windows 7 and Windows Server 2008 R2	SP1	GDR
6.1.760 1.21xxx	Windows 7 and Windows Server 2008 R2	SP1	LDR

GDR service branches contain only those fixes that are widely released to address widespread, extremely important issues. LDR service branches contain hotfixes in addition to widely released fixes.
The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
