PolicyMaker registry extension crashes Group Policy snap-in

Thank you Microsoft :) 

If you use PolicyMaker, there is a nice issue whenever you try to view the PolicyMaker extensions in a GPO it will crash your MMC session.  Looks like it’s an issue with IE7

To resolve this issue, configure the following registry value in Registry Editor:

HKEY_LOCAL_MACHINE\\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_OBJECT_CACHING\mmc.exe

To do this, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
2. Locate the following registry subkey, and then right-click it:

   HKEY_LOCAL_MACHINE\\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_OBJECT_CACHING

3. Point to New, and then click DWORD Value.
4. Type mmc.exe to name the value, and then press ENTER. Leave the value at 0.
5. Exit Registry Editor.
