Windows stores many Group Policy settings in the Registry. The Registry is a database on each Windows computer that stores configuration settings for the computer and users. The Group Policy Settings Reference spreadsheet lists the key locations for settings stored in the Registry. The Registry stores Group Policy settings either in HKEY_CURRENT_USER (HKCU) or HKEY_LOCAL_MACHINE (HKLM). HKCU keys define settings that are specific to each user. HKLM keys define settings that apply to the computer, regardless of who is logged on.
