InformationThis setting controls whether or not Windows Installer should use system permissions when it installs any program on the system.
Note: This setting appears both in the Computer Configuration and User Configuration folders. To make this setting effective, you must enable the setting in both folders.
Caution: If enabled, skilled users can take advantage of the permissions this setting grants to change their privileges and gain permanent access to restricted files and folders. Note that the User Configuration version of this setting is not guaranteed to be secure.
The recommended state for this setting is: Disabled.
Users with limited privileges can exploit this feature by creating a Windows Installer installation package that creates a new local account that belongs to the local built-in Administrators group, adds their current account to the local built-in Administrators group, installs malicious software, or performs other unauthorized activities.
SolutionTo establish the recommended configuration via GP, set the following UI path to Disabled:
User Configuration\Policies\Administrative Templates\Windows Components\Windows Installer\Always install with elevated privileges
Note: This Group Policy path is provided by the Group Policy template MSI.admx/adml that is included with all versions of the Microsoft Windows Administrative Templates.
None - this is the default behavior.
Disabled. (Windows Installer will apply the current user's permissions when it installs programs that a system administrator does not distribute or offer. This will prevent standard users from installing applications that affect system-wide configuration items.)
