[Forum FAQ] The Value drop down list is grayed out when you perform search for Group Policy Objects in GPMC

Question

Symptom
On Windows Server 2012 or Windows Server 2012 R2, when you use the Search for Group Policy Objects feature in GPMC, the “Value” field is not populated when you choose “User Configuration” as the Search Item. (See Figure 1.)
<Figure 1>
Cause
The happens because the  Data of the (Default) value of the following Registry Key is not correct.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{4D2F9B6F-1E52-4711-A382-6A8B1A003DE6}]
By default the Data is (value not set). (see Figure 2)
<Figure 2>
Resolution
The registry keys under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions] are the Group Policy Preference Client Side Extensions. The CSE name of the GUID {4D2F9B6F-1E52-4711-A382-6A8B1A003DE6} is
RemoteApp and Desktop Connections. Please follow the steps below to resolve the issue.
1. Locate the registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{4D2F9B6F-1E52-4711-A382-6A8B1A003DE6}]
2. Take the ownership of this key: Right click on the registry key and choose Permissions option and click the Advanced button on the dialogue window. Then on the Advanced Security Settings dialogue window, click Change button to take the ownership
of the key for the current logon account and make the current logon account Full Control permission with the registry key. (See Figure 3.)

3. Change the data of (Default) value from "(value not set)" to
"RemoteApp and Desktop Connection Component". (See Figure 4)
<Figure 4>
4. Once the steps above are completed, the Value drop down list will be populated again when you perform Search in GPMC. (See Figure 5)
