Getting started with VirtualZones

Install VirtualZones, understand zones, and confine your first fullscreen app in under a minute.

VirtualZones splits your monitor into vertical zones that behave like separate monitors. This guide gets you from download to your first confined app.

Install and launch

  1. Download VirtualZones.exe (or the installer) from the latest release.
  2. Run it. There is nothing to install for the portable exe — no admin rights, no runtime.
  3. On launch it immediately starts confining with the default 25% / 50% / 25% layout and thin blue zone borders.

If you see a “Windows protected your PC” message, that is Microsoft Defender SmartScreen for unsigned apps — click More info → Run anyway.

Confine your first app

Maximize any window, or press F11 in a supporting app. Instead of taking over the whole display, it snaps into the zone it was in and fills exactly that region — like a real monitor. The other zones stay usable.

Try it with a video call: put Zoom or Teams in the center zone and maximize it. It fills the clean 2560×1440 center while your browser and notes stay visible on either side.

Change the layout

Open the Layout dropdown in the control panel and pick 50% / 50% or 33% / 33% / 33%, or choose Edit Layouts… to build your own — see Building custom layouts.

Stop and start

  • Hide zones removes the borders but keeps confinement running.
  • Stop releases every window.
  • Global hotkey Ctrl+Alt+R toggles start/stop from anywhere.

That’s the whole idea: the productivity of a multi-monitor setup, from one panel, without the OS ever knowing.
