Remmina

Remmina is the standard tool for the reverse-direction problem: connecting FROM Linux TO other machines. Its RDP support (via FreeRDP) is excellent — full Windows remote desktops with clipboard, drive redirection, multi-monitor, and credential storage — plus VNC, SSH, and SPICE in the same tabbed interface. For admins and anyone keeping a Windows box around for that-one-app, it’s essential.

It’s a client only: it won’t let others control your Linux machine (use RustDesk or KDE’s krfb for that). Connection quality mirrors the protocol — RDP is great, VNC is VNC. The interface is dated-functional, and occasional FreeRDP version quirks break specific server configs until a patch lands.
