Windows Server 2012 and Windows 8 include support for over 350 new group policy settings ...This brings the total number of manageable system policies via Active Directory group policy to over 3,600 policy settings!  Below, I've summarized the new categories of group policy settings that I'm most excited about and I've also provided a link to a downloadable reference workbook ...

What's New in Active Directory Group Policies?

These new Group Policy settings provide improved management for new areas of these operating systems, such as:

• Managing enterprise installation of Windows 8-style application packages (AppX)

• Start Screen customization settings, such as Show "Run as Different User" on Start screen and clearing History on tile notifications
• User Setting Sync configuration (ie., "Sync your Settings" to Skydrive)
• New Folder Redirection settings that can configure redirection on a user's "primary computer" only
• User Profile roaming settings that can configure roaming on a user's "primary computer" only

• Printing settings to handle the new v4 simplified print provider architecture

Do I need to update my Active Directory schema to deploy these new Group Policies? 

According to the reference document, only three (3) of these new Group Policy Settings requires that the AD Schema be updated to Windows Server 2012.  These new Group Policy Settings are:

• Turn on TPM backup to Active Directory Domain Services
• Redirect folders on primary computers only
• Download roaming profiles on primary computers only

 Where can I download an updated reference for all Group Policy settings?
