Group policy settings (and all of them)
This spreadsheet lists the policy settings for computer and user
configurations included in the administrative template files
(admx/adml) delivered with Windows Vista (RTM build 6000). The policy
settings included in this spreadsheet cover Windows Vista, Microsoft
Windows Server 2003, Windows XP Professional, and Windows 2000. These
files are used to expose policy settings when you edit Group Policy
objects (GPOs) using Group Policy Object Editor (also known as GPEdit).
This is an extremely usefull document as it also includes what registry keys are needed to (dis)allow a certain setting. (Handy to use in scripts 
)
