Limit group policy only to client OS

Sometimes you want to apply your policy to every client PC in many OUs. To do such you can use WMI filter. This is especially useful in messy AD structures, where is no dedicated OU for client computer objects.

Namespace: root\CIMv2
Query: select * from Win32_OperatingSystem where ProductType="1"

I use here following WMI Class and property:

Can’t access any Outlook tabs on ribbon except Enterprise Vault

Recently one of our customers installed Microsoft Dynamics CRM Outlook add-in and discovered that after this action Microsoft Outlook became absolutely useless, because after start of the program there are no other tabs except Enterprise Vault, which is also used by this customer. Little research showed that the root of the problem is in some components of earlier version of Microsoft Office. To fix problem you need to delete following registry key:

HKEY_CLASSES_ROOT\TypeLib\{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52}\2.4

To automate this across organization you can use group policy preferences:

Computer Configuration -> Preferences -> Windows settings ->Registry -> New -> Registry Item:

Action: Delete
Hive: HKEY_CLASSES_ROOT
Key Path: TypeLib\{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52}\2.4
