What is razerhid-exe?

razerhid-exe is the Razer HID Host Driver that powers input from Razer peripherals such as keyboards, mice, and controllers. It translates hardware HID reports into Windows events and coordinates with Razer Synapse to apply device-specific features like macros, lighting, and profile configurations. It runs in the background to ensure instant response during gaming and daily use.

razerhid-exe acts as a user-mode bridge that reads HID data from Razer devices, passes input to Windows, and communicates with Synapse to enforce per-device settings, lighting effects, and macros with low latency.
