SUMMARY

When a group policy is being processed on a Windows-based computer, client-side extensions are the components that interpret the stored policy and make the appropriate changes to the environment. In troubleshooting a given extensions' application of policy, the administrator can view the configuration parameters for that extension. These parameters are in the form of registry values.

MORE INFORMATION

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

Each client-side extension is identified by a subkey beneath the following path:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions
The subkey name takes the form of a Globally Unique Identifier (GUID). For more information about identifying registered group policy client-side extensions, see the following article in the Microsoft Knowledge Base:
216357 Identifying Group Policy Client-Side Extensions

Registry Values for Client-Side Extensions
