Is the SilentCleanup UAC bypass technique applicable to Windows 7 or Windows 8?

The technique works on Windows 10 (up to RS2) and Windows 8, but not on Windows 7 because that OS lacks the `SilentCleanup` scheduled task entirely. The article notes that Microsoft planned to patch it in Windows 10 RS3. This method is a refinement of earlier UAC bypasses, such as the one using Disk Cleanup described by Matt Nelson, which has since been patched.
