All of the notebook computers come with function keys that work together with the special function key labeled with Fn. For example, there are function keys for changing the screen brightness, for switching between in-built and external monitors, for toggling on or off webcam, for toggling on/off the WiFi or Bluetooth, for changing the volume etc. Similarly, there are multimedia keyboards available for the desktop computers that come with special multimedia keys that can be used to change the volume, open the default web browser, launch the email client, control the media playback and so on.
When we control the volume using any of these function keys or multimedia keys, the operating system displays an overlay volume control to indicate the changed volume levels. This over the screen display (OSD) is not shown when we change the volume using the speaker icon in the notification area of the Windows desktop.
While this Media OSD that shows the volume bar graphic on the screen near the top-left corner of the monitor is only there for a few seconds, it can be annoying for some people. If you try to change the volume when you are watching a livestream show, a music video or movie, this volume bar OSD could be distracting.
There is a simple solution for disabling this volume bar OSD using an open-source tool called MediaOsdToggle. It is a no-gui, no-command-line application that can be run by double-clicking on its file MediaOsdToggle.exe. The program runs silently without showing any user interface of any kind, does its job and then closes. The whole thing happens so fast that you might feel like nothing happened.
If you run MediaOsdToggle.exe once, it will disable the media OSD for your Windows PC. And if you want to enable it again, then you can run the same program again. Nothing can be easier than this.
