  • Virtual keyboard display. The program renders a full keyboard layout on the screen, with each physical key press immediately highlighted on the virtual representation. This visual feedback confirms whether a specific button registers correctly and helps isolate dead or intermittent keys.
  • Key press history. A record of previously pressed keys is maintained and displayed in a distinct shade separate from currently active keys. This feature lets you review the sequence of tested buttons and detect keys that may have failed earlier in the session.
  • Reset function. A dedicated Reset button, located in the lower section of the interface, clears the entire history of pressed keys. This action returns the virtual keyboard to its initial state, allowing a fresh test cycle without restarting the application.
  • Scan code retrieval. The utility captures and displays keyboard scan codes, which are numeric sequences the operating system uses to translate physical key presses into commands. These codes assist in advanced diagnostics, driver troubleshooting, and remapping configurations.
  • Light theme. The application includes a light color scheme for the virtual keyboard and interface elements. This option suits brightly lit environments and reduces visual strain when the surrounding illumination is high.
  • Dark theme. A dark color scheme is available for the virtual keyboard and interface elements. This option decreases glare in low-light conditions and provides comfortable viewing during extended testing sessions.
  • Multiple keyboard models. The program offers several keyboard layout models, covering standard desktop keyboards and notebook configurations. Selecting the appropriate model ensures the virtual layout matches the physical device being tested.
  • Notebook layout support. Specific layouts for laptop keyboards are included, accounting for compact key arrangements, function key rows, and embedded numeric pads. This support enables accurate testing on portable computers.
  • Portable operation. The application requires no installation or configuration and runs directly after being downloaded. This characteristic permits testing on multiple computers from removable media without modifying the host system.
  • Key state visualization. Active keys and previously pressed keys appear in different shades on the virtual keyboard. This distinction separates the current input from historical data and simplifies the interpretation of test results.
  • Compatibility scope. The utility supports Windows Vista and later versions, with Windows XP support discontinued after version 2.2.0. This range covers most modern desktop and laptop systems running Microsoft operating systems.
  • Compact resource usage. The program operates as a lightweight tool that consumes minimal system memory and processing power. This behavior allows simultaneous use with other diagnostic applications without affecting performance.

The development of Keyboard Test Utility is led by Javad Taheri, who maintains the project through its official GitHub repository. The program originated as a practical solution for verifying keyboard hardware and has received regular releases since its initial publication. Version 2.2.0 marked the end of support for Windows XP, reflecting a shift toward modern Windows platforms.
