Keep full-screen Remote Desktop (mstsc) sized to the monitor work area, so the host taskbar stays visible and the session renders 1:1.

mstsfence makes mstsc.exe, in full-screen mode, size itself to the monitor's work area instead of the whole monitor -- so the host taskbar stays visible (host taskbar on the bottom, session taskbar on top) and the remote desktop renders 1:1, with no scaling or letterboxing. A small tray controller installs a global hook that the OS maps into mstsc however it was launched (.rdp file, jump list, Start menu); outside mstsc it does nothing. Inside mstsc it clamps the monitor-geometry APIs the client reads to the work area, tracking DPI and resolution changes live. An optional dark-mode pass and a host display-scaling (DPI) override are included. Staying on stock mstsc keeps all of its credential UX, Credential Manager integration, and certificate/consent dialogs.
