VirtualDesktopTray

A lightweight tray tool for Windows 11 to quickly show and switch between Virtual Desktops.
It uses VirtualDesktopAccessor.dll for native API access.

Features

• Shows the current Virtual Desktop number as a tray icon.
• Context menu in tray to jump directly to any desktop.
• Left-click on tray icon cycles through desktops (wrap-around when reaching the last one).
• Small and resource-friendly (single executable, ~150 KB + dependency DLL).
• Compatible with Windows 11 only (Windows 10 DLL not supported).

---

Dependencies

• .NET 9.0 Runtime
  (unless built as self-contained publish).
• VirtualDesktopAccessor.dll
  – must be placed in the same directory as VirtualDesktopTray.exe.

---

Build

Clone this repo and build with .NET SDK 9.0+:

git clone https://github.com/USERNAME/VirtualDesktopTray.git
cd VirtualDesktopTray
dotnet build -c Release

This produces:

bin/Release/net9.0-windows/VirtualDesktopTray.dll
bin/Release/net9.0-windows/VirtualDesktopTray.exe

Publish as single EXE (optional)

If you don’t want to require users to install the .NET runtime:

dotnet publish -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true --output ./publish

This will generate a standalone VirtualDesktopTray.exe (~100 MB) in:

publish/

You still need to ship VirtualDesktopAccessor.dll alongside it.

Usage

1. Place VirtualDesktopTray.exe and VirtualDesktopAccessor.dll in the same folder.
2. Run VirtualDesktopTray.exe.
3. A tray icon will appear:
   • Number shows your current desktop.
   • Left click → jump to next desktop.
   • Right click → open context menu, jump directly to any desktop, or exit.

Notes

• Works only on Windows 11 (build 22000 or newer).
• Windows 10 builds of VirtualDesktopAccessor.dll are not compatible.
• Minimal resources: updates icon every 200 ms, practically no CPU usage.
