The group policy setting for the week this week is a new policy setting for Windows 7/2008 R2. This setting is called "Prevent changing mouse pointers" and can be found under User Configuration > Policies > Administrative Templates > Control Panel > Personalization. This setting is handy if you want to tightly control the user environment such as public access computers in a library or a common shared computer.
Below you can see how the "pointers" tab is removed when the policy is enabled.
