Windows Server 2025 must prevent users from changing installation options.

Installation options for applications are typically controlled by administrators. This setting prevents users from changing installation options that may bypass security features.

If the following registry value does not exist or is not configured as specified, this is a finding:

Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows\Installer\

Value Name: EnableUserControl

Type: REG_DWORD Value: 0x00000000 (0)

Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Windows Installer >> Allow user control over installs to "Disabled".
