This policy setting specifies whether Windows Messenger can collect anonymous information about how the Windows Messenger software and service is used. Counter Measure: Enable this policy setting to ensure that Windows Messenger does not collect usage information and to prevent display of the user settings that enable the collection of usage information. Potential Impact: Microsoft uses information collected through the Customer Experience Improvement Program to detect software flaws so that they can be corrected more quickly, enabling this setting will reduce the amount of data Microsoft is able to gather for this purpose. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Internet Communication Management\Internet Communication settings\Turn off the Windows Messenger Customer Experience Improvement Program (2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Messenger\Client!CEIP
