Remove HKCU Registries from All Users

Use this predefined action to remove HKEY_CURRENT_USER (HKCU) registry entries from every existing user profile and from the default user profile during a SYSTEM-context installation or uninstallation.

This lets you remove per-user settings for all users even when the MSI runs under SYSTEM, which is common in enterprise deployments.
