In 2021, HP transitioned much of its support infrastructure. While there isn't a standalone "HP M100 Gaming Software" file to download, you can ensure your mouse works correctly by downloading the latest Human Interface Device (HID) drivers or HP peripheral utilities.

Note: Be wary of third-party "Driver Downloader" tools that pop up in search results. These often bundle malware. Always stick to official HP or Microsoft sources. In 2021, HP transitioned much of its support infrastructure
Important Note: HP did not release a new driver exclusively labeled "2021" for the M100. Instead, “2021” refers to the driver version that was fully compatible with Windows 10 20H2 and early Windows 11 builds. The last stable driver package was published in late 2020 and remained the standard throughout 2021. Note: Be wary of third-party "Driver Downloader" tools
To understand the importance of the driver download, one must first appreciate what a driver actually does. At its core, a driver is a low-level software program that allows the operating system (OS)—be it Windows 10, macOS, or Linux—to communicate with a hardware device. Without a driver, the HP M100 would still function as a generic Human Interface Device (HID), providing basic left-click, right-click, and cursor movement. However, all advanced features would be lost: programmable buttons, DPI (dots per inch) switching, polling rate adjustments, LED customization, and macro recording.
In 2021, Windows 10 had become remarkably adept at automatically fetching generic drivers via Windows Update. Plug in an M100, and within seconds, the mouse would work. But for a gamer, “work” is not enough. The M100’s selling points—four DPI presets (800, 1200, 2400, and 3200), two side buttons, and customizable RGB lighting—required the official HP driver package, often bundled with HP’s gaming software suite. Thus, the act of downloading the driver was not a mere formality; it was an act of unlocking the device’s true potential.
This lightweight utility was the only way to turn off the breathing LED effect or lock in a specific DPI step.
