TeamViewer is an external, cross-platform remote assistance tool that operates via the Internet, allowing remote access without requiring a VPN or intricate network setups. It accommodates various operating systems and provides functionalities like file transfer, remote printing, and session recording. Conversely, Remote Desktop (like Microsoft’s Remote Desktop Connection) is built into Windows and is primarily utilized within corporate environments, usually necessitating VPN access for external connections. Although Remote Desktop is an integrated and affordable option for Windows systems, TeamViewer's versatility and extra functionalities render it more appropriate for varied and dispersed teams.
