Legacy Update Help

Are there command line switches I can use with Legacy Update?

Here are the switches supported by Legacy Update setup:

/SSilent installation. Displays no UI and proceeds with default configuration. If a restart is required, Legacy Update setup will exit with error level 3010. The Legacy Update website will not be opened after installation completes. (Case sensitive - the flag is a capital S, not lowercase.)
/passivePassive installation. Similar to /S, but still displays the setup user interface, and may display error or question dialogs. Added in Legacy Update 1.10.
/norestartDon’t restart automatically. Instead, a dialog will prompt you to restart (unless /S has also been passed). Legacy Update will resume immediately after the restart.

Here are the switches supported by the Legacy Update launcher (LegacyUpdate.exe):

/launchLaunch Legacy Update website in Internet Explorer. If no parameters are provided, /launch is assumed.
/optionsOpen the Windows Update options control panel.
/logOpen the Windows Update log file in the default program for .log files. On Windows 10 and later, executes the cmdlet Get-WindowsUpdateLog in PowerShell, and then opens the resulting log file.
/regserverRegister the ActiveX control with the system. Executed automatically by Legacy Update setup during installation.
/unregserverUnregister the ActiveX control with the system. Executed automatically by Legacy Update setup during uninstallation.
