Consider the following scenario:

• You set up a Windows Management Instrumentation (WMI) notification query to monitor event log changes on a Windows Server 2008-based or Windows Vista-based computer.
• Some events are added that trigger the WMI notification query.

In this scenario, the memory usage of one instance of the wmiprvse.exe process increases quickly until the memory is exhausted.

You log on to a Windows Vista-based or Windows Server 2008-based computer by using an administrator account. When you run a Windows Management Instrumentation (WMI) query against the CIM_DataFile class, the WMI query returns incomplete results.

This problem occurs if you run the WMI query by using the Run as administrator option (Elevated Permission).

For example, when you run the following query by using the Run as administrator option, the query returns incomplete results.

Select * from CIM_DataFile where filename = filename and extension = extension_name

This issue does not occur if you run the query without the Run as administrator option.

Windows Management Instrumentation: A set of extensions to the Windows Driver Model that provides an operating system interface through which instrumented components can provide information and notification.

On a computer that is running Windows Vista or Windows Server 2008, you use the Win32_PerfRawData_PerfDisk_LogicalDisk Windows Management Instrumentation (WMI) class to calculate the percentage of free disk space. However, the free disk space percentage that is returned is incorrect.

When you run a script to perform a Windows Management Instrumentation (WMI) query for TCP/IP ports on a computer that is running a non-English version of Windows Vista, the query results may be empty. This issue occurs even if TCP/IP ports are installed on the computer. The issue causes the script to be unable to detect the installed TCP/IP ports.

Additionally, you may encounter some function failure. For example, you may be unable to install a printer by using a script that resembles the following script to install a printer:

SELECT * FROM Win32_TCPIPPrinterPort

Note: The issue does not occur on a computer that is running the English version of Windows Vista.

The Windows Management Instrumentation (WMI) service stops responding on a computer that is running the Microsoft .NET Framework 2.0 and Microsoft System Center Configuration Manager 2007.

The Windows Resource Kit tool Moveuser.exe is incompatible with Windows Vista. In earlier versions of Windows, Moveuser.exe is used to map an existing local user account profile to a new domain profile when a computer in a workgroup is joined to a domain. Alternatively the tool can also used to map an existing domain account profile to another new domain account profile. However, you cannot use the Moveuser.exe tool to perform these tasks on a Windows Vista-based computer.

When you run a program that uses the Offline Files Windows Management Instrumentation (WMI) Provider on a Windows Vista-based computer, the WMI Provider Host program (Wmiprvse.exe) may stop responding.

On a Windows Vista-based computer, you use a custom application that gathers system information by using Windows Management Instrumentation (WMI). For example, you use a custom application gathers information about hardware, drivers, or firmware by using WMI. When you do this, WMI may not correctly report information about certain USB disk devices. Because of this problem, the custom application may not correctly recognize the USB disk device.
