Directs Windows Installer to use system permissions when it installs a program. By default, Windows Installer uses the user's permissions to install programs.

This entry stores the setting of the Always install with elevated privileges Group Policy. Group Policy adds this entry to the registry with a value of 1 when you enable the policy. If you disable the policy, Group Policy sets the value to 0. If you set the policy to Not configured, Group Policy deletes the entry from the registry, and the system behaves as though the value is 0.



0 (or not in the registry)

The policy is disabled or not configured. Use the current user's permissions, except when installing published or assigned programs.


The policy is enabled. Use system permissions.

This entry extends elevated permissions to all programs. These permissions are usually reserved for programs that have been assigned to the user (offered on the desktop), assigned to the computer (installed automatically), or made available in Add/Remove Programs in Control Panel. This entry lets a user install programs that require access to directories that the user might not have permission to view or change, including directories on highly restricted computers.

Change method

To change the value of this entry, use Group Policy. This entry corresponds to the Always install with elevated privileges Group Policy (Computer Configuration\Administrative Templates\Windows Components\Windows Installer).

Note Image Note

This entry can appear in both the HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER subtrees. If it appears in both subtrees, the entry in HKEY_LOCAL_MACHINE takes precedence over the entry in HKEY_CURRENT_USER.

Skilled users can take advantage of the permissions this entry grants to change their permissions and gain permanent access to restricted files and folders. Note that the User Configuration version of this entry is not guaranteed to be secure.
