"connection file" -- Specifies the name of an .RDP file for the connection.
/v:<server[:port]> -- Specifies the remote PC to which you want to connect.
/g:<gateway> -- Specifies the RD Gateway server to use for the connection. This parameter is only read if the endpoint remote PC is specified with /v.
/admin -- Connects you to the session for administering a remote PC.
/f -- Starts Remote Desktop in full-screen mode.
/w:<width> -- Specifies the width of the Remote Desktop window.
/h:<height> -- Specifies the height of the Remote Desktop window.
/public -- Runs Remote Desktop in public mode.
/span -- Matches the remote desktop width and height with the local virtual desktop, spanning across multiple monitors, if necessary. To span across monitors, the monitors must be arranged to form a rectangle.
/multimon -- Configures the Remote Desktop Services session monitor layout to be identical to the current client-side configuration.
/edit -- Opens the specified .RDP connection file for editing.
/restrictedAdmin -- Connects you to the remote PC in Restricted Administration mode. In this mode, credentials won’t be sent to the remote PC, which can protect you if you connect to a PC that has been compromised. However, connections made from the remote PC might not be authenticated by other PCs, which might impact application functionality and compatibility. This parameter implies /admin.
/remoteGuard -- Connects your device to a remote device using Remote Guard. Remote Guard prevents credentials from being sent to the remote PC, which can help protect your credentials if you connect to a remote PC that has been compromised. Unlike Restricted Administration mode, Remote Guard also supports connections made from the remote PC by redirecting all requests back to your device.
/prompt -- Prompts you for your credentials when you connect to the remote PC.
/shadow:<sessionID> -- Specifies the ID of the session to shadow.
/control -- Allows control of the session when shadowing.
/noConsentPrompt -- Allows shadowing without user consent.
