Microsoft Trackball Optical Driver

The Microsoft Trackball Optical is a stationary pointing device that lets you move the cursor by rolling a thumb-operated ball. Its driver enables Windows to recognize the trackball and handle pointer movement, clicks, and scrolling; compatible Microsoft mouse software may also provide button customization.

Key Features

• Trackball input support: Enables cursor control and standard button functions without moving the device across your desk.
• Scroll-wheel operation: Supports scrolling through documents, web pages, and other applications that accept wheel input.
• Pointer adjustments: Works with Windows mouse settings so you can adjust pointer speed, swap primary buttons, and fine-tune double-click behavior.
• Optional button customization: Compatible Microsoft configuration software may let you assign actions to additional buttons. Availability depends on the software version and operating system.

How to Install

1. Check your Windows version. Open your system information to confirm whether you use Windows 11, Windows 10, Windows 8, or Windows 7, and whether the installation is 32-bit or 64-bit. Choose a package that explicitly supports your configuration.

1. Connect the trackball. Plug the Microsoft Trackball Optical into an available USB port. Windows may install a built-in mouse driver automatically, providing basic operation without a separate download.

1. Download a compatible driver if needed. If basic functions are missing or you need additional button controls, check the download’s compatibility information before proceeding. Older Microsoft mouse software is not necessarily compatible with every listed Windows version.

1. Install the software. If the download includes an installer, run it and follow the prompts. For a driver-only package, extract the files, open Device Manager, locate the trackball under mice or pointing devices, and select Update driver to browse to the extracted folder.

1. Test and configure the trackball. Restart if prompted, then check cursor movement, clicking, and scrolling. Adjust standard behavior in Windows mouse settings, and use compatible configuration software for any supported extra-button assignments.

For this older Microsoft input device, basic Windows driver support and optional customization software are separate considerations. If the trackball already works correctly, an additional legacy software package may not be necessary.
