The PC/AT Enhanced PS/2 Keyboard (101/102-Key) driver allows Windows to recognize a compatible PS/2 keyboard and process typing, shortcuts, and navigation keys. This Microsoft input driver is intended for users setting up a standard 101/102-key keyboard or troubleshooting a keyboard that is missing, unresponsive, or showing an error in Device Manager. Windows typically includes the necessary driver, so a separate download is often unnecessary.
Key Features
- Standard keyboard support: Enables input from compatible 101/102-key PS/2 keyboards, including function keys, navigation keys, and the numeric keypad.
- Windows integration: Works with the Windows keyboard input system and the language and layout settings you select.
- Built-in driver management: Allows Windows to detect the keyboard and manage its driver through Device Manager.
- Compatibility with older Windows releases: Supports compatible hardware running Windows 10, 8.1, 7, Vista, and XP, using the driver supplied for each operating system.
How to Install PC/AT Enhanced PS/2 Keyboard (101/102-Key) Driver
- Check your hardware and operating system. Confirm that your keyboard uses a PS/2 connection and identify your Windows version. If connecting a PS/2 keyboard, shut down the computer before plugging it in, then start Windows.
- Let Windows detect the keyboard. The operating system normally installs its built-in Microsoft keyboard driver automatically. If typing works correctly, no additional installation may be needed.
- Open Device Manager. Expand Keyboards, locate the keyboard entry, and open Properties to check its status. If the keyboard is unusable, use a USB keyboard or the Windows on-screen keyboard.
- Check for an update. Right-click the keyboard entry and choose the driver update option, then let Windows search automatically. You can also check Windows Update for applicable updates.
- Install a separate package only if required. When choosing a PC/AT Enhanced PS/2 Keyboard (101/102-Key) driver download for Windows, verify its source and exact OS compatibility. Follow the package instructions and restart if prompted. A free download should not require an unrelated driver-updater subscription.
Keep the driver updated through Windows or your computer manufacturer’s support resources rather than replacing a working driver unnecessarily. The latest version suitable for your system may already be installed. For Windows 10/11 troubleshooting, check hardware detection and connection issues first; Windows 11 is not included in this page’s listed supported operating systems.
