There are over 1500 Group Policies for managing Windows Internet Explorer 9. Configuring these for the first time may seem like a daunting task. Group Policies can be set in either Machine or User scope. Machine policy takes precedence over user policy. Finally, the policy path is where the policy is located under the Administrative Templates in the Group Policy editor.
This spreadsheet from Microsoft lists all the policy settings for computer and user configurations included in the administrative template files (admx/adml) delivered with Windows Internet Explorer 9, including the new settings. The policy settings included in this spreadsheet cover Internet Explorer 5, Internet Explorer 6, Internet Explorer 7, Internet Explorer 8 and Internet Explorer 9. These files are used to expose policy settings when you edit Group Policy objects (GPOs) using Group Policy Object Editor (also known as GPEdit).
The Group Policies are listed here with information on the policy setting name, scope, and policy path. The policy setting name gives a short description of what the policy does.
