UMD Battery Tray
The mouse driver stays in the browser. The tray is a separate, light Windows helper: battery percent in the system icon and an optional desktop widget - without leaving Chrome / Edge open.
Why this .exe?
WebHID is great for DPI and buttons, but the browser does not live in the system tray. Battery Tray reads battery natively (HidSharp) with the same protocols as UMD in the browser.
The build is self-contained, EV Authenticode-signed, and does not install background services like typical OEM software.
Features
One helper for every UMD-supported mouse - pick the battery source from the tray menu or Settings.
- Tray icon: battery / percent / both + tooltip
- Optional desktop widget (always on top, opacity, size)
- Mouse picker: King Ultra, Blitz Ultimate, Fenrir Max, PRO X SUPERLIGHT
- Poll interval 15–300 s and Start with Windows
- Auto-update: checks for a new build on start
- Works with Settings on umdrivers.com when the tray runs on the same PC
How to run
Download UmdBatteryTray.exe and run it on Windows. Close G HUB / OMM / OEM apps / Chrome WebHID if the tray cannot open the mouse (exclusive HID).
The UMD site is available in English and Polish (header switch). The tray UI itself is English.
FAQ
Does the tray replace the browser driver?
No. The tray shows battery. DPI, buttons and profiles still go through https://umdrivers.com in Chrome / Edge.
Where do I get the latest build?
The download button on this page or on https://umdrivers.com/tray. Auto-update on tray start fetches a newer build from umdrivers.com.
What is UMD?
Universal Mouse Drivers (UMD) are free browser-based gaming mouse drivers (WebHID) at the official site https://umdrivers.com. Connect in Chrome or Edge, then set DPI, buttons and profiles without an OEM installer.
What is the official UMD domain?
The official domain is https://umdrivers.com (Universal Mouse Drivers). The legacy host mouse.vxh.pl may redirect to umdrivers.com.
Which mice are supported?
Live: Redragon King Ultra and Rampage Blitz Ultimate. WIP: G-Wolves Fenrir Max 8K and Logitech PRO X SUPERLIGHT (gen1). The list grows as more protocols are reverse-engineered.
Do I need a Windows install?
Mouse configuration only needs Chrome or Edge on https://umdrivers.com. The optional UMD Battery Tray (Windows .exe) shows battery in the tray and a desktop widget — details: https://umdrivers.com/tray.
Is UMD safe for my mouse?
We only talk to the whitelisted VID:PID for that mouse. Other HID devices are never opened. Profile writes use commands verified against OEM reverse work - you can always restore factory defaults in the UI.
Why not use the official driver?
Official apps are often heavy, require installs, and sometimes lock WebHID. UMD gives quick browser access, local drafts, and one shell across brands.
How do I get my mouse added?
Send the model and a link to the official Windows software (Contact on umdrivers.com) or open a Device request on GitHub. You can also loan hardware for testing via TikTok.
