Description:
Disables or restricts the use of Windows Installer.
This setting can prevent users from installing software on their systems or permit users to install only those programs offered by a system administrator.
If you enable this setting, you can use the options in the Disable Windows Installer box to establish an installation setting.
-- The "Never" option indicates that Windows Installer is fully enabled. Users can install and upgrade software. Windows Installer is enabled by default on Windows 2000.
-- The "For non-managed apps only" option permits users to install only those programs that a system administrator assigns (offers on the desktop) or publishes (adds them to Add or Remove Programs).
-- The "Always" option indicates that Windows Installer is disabled.
This setting affects Windows Installer only. It does not prevent users from using other methods to install and upgrade programs.
