Group Policies - Specific GPOs and Settings for Windows 7

Hello Experts,

I could use a real GPO guru's help here.  I'm looking for specific GPOs settings and options that are new for Windows 7 only.  Understanding that Group Policies have been around a long time, I need to know which NEW GPOs and their settings have been introduced as new for Windows 7.

I'm researching what GPO options are available for Windows 7 workstations vs. what is already available for Windows XP and Vista workstations.

If I'm not being real clear in what I'm asking, as I may be asking it wrong, please let me know and I'll be happy to clarify.  Thanks Experts!
