Any Windows machine with the Windows Installer service is in scope, and shared or multi-user Windows systems carry the most risk because the attacker must already hold a local account. The sources do not list affected Windows builds or whether any non-default configuration is required. Systems where only a single trusted user logs in are lower risk.
