MICROSOFT PS2 MOUSE Driver

The MICROSOFT PS2 MOUSE driver helps Windows recognize a PS/2-connected mouse and process movement, clicks, and scrolling where supported. This page is intended for Lenovo users who need to restore mouse input after reinstalling Windows, troubleshoot a detection issue, or check for a compatible driver update.

Key Features

• Essential mouse input: Supports pointer movement and button actions, with wheel scrolling available on compatible hardware.
• Windows input integration: Works with Windows mouse settings so you can adjust pointer speed, button configuration, and other available options.
• Legacy system support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; check the individual package details before choosing a download.
• Driver recovery: Installing a compatible driver may help resolve missing or incorrectly configured mouse entries in Device Manager. It will not fix a damaged cable or PS/2 port.

How to Install MICROSOFT PS2 MOUSE Driver

1. Confirm your system details. Check your Lenovo model, Windows edition, and whether your installation is 32-bit or 64-bit. If you are comparing Windows 10/11 options, note that Windows 11 is not included in this device’s listed support.
2. Choose a compatible package. Before starting a MICROSOFT PS2 MOUSE driver download for Windows, review the supported hardware and operating systems. Select the latest version that explicitly matches your system; a newer package is not automatically the right choice.
3. Check the connection. Shut down the computer before connecting or reseating a PS/2 mouse, then turn it back on. Windows may recognize the mouse using its built-in driver without a separate download.
4. Install if needed. If a compatible package includes an installer, follow its instructions. For extracted driver files, open Device Manager, locate the mouse or unidentified input device, select Update driver, and browse to the extracted folder. Older Windows versions may use slightly different labels.
5. Restart and test. Restart if prompted, then check movement, clicking, and scrolling. If problems began after an update, use Roll Back Driver in Device Manager when available.

Keep the driver updated through Windows Update or a verified Lenovo support source when a compatible fix is available. A free download should still be checked for hardware compatibility and a trustworthy publisher. If your mouse already works reliably, there is usually no need to replace its working driver simply to obtain a newer version.
