Corsair HID Service (corsair-hid.exe)
corsair-hid.exe is a background Windows process that powers HID communication for Corsair peripherals, enabling keypress reporting, lighting control, and macro handling through the iCUE software. It runs continuously to keep Corsair keyboards, mice, and other devices responsive, synchronized with profiles, and ready to receive input and apply effects in real time.
It interfaces with USB HID drivers to translate hardware events into iCUE actions and lighting instructions. It also forms a bridge between Corsair hardware and software, delivering low-latency input handling and profile-based settings via shared memory or IPC with iCUE.
corsair-hid.exe is a legitimate component of the Corsair iCUE software suite. When installed from official Corsair sources and located in the Corsair program directories, it functions as a core service that handles HID input/output for Corsair peripherals, enabling lighting effects, macro execution, and device discovery. If you obtained iCUE from Corsair's official site and the file resides in expected subfolders, it is generally safe and required for full peripheral functionality.
There are cases where malware masquerades as corsair-hid.exe to evade detection, but legitimate Corsair HID activity should originate from Corsair directories (e.g., C:\Program Files (x86)\Corsair\ or C:\Program Files\Corsair\) and be digitally signed by Corsair. If the binary is missing signatures, located in an unexpected path, or shows unusual behavior like invasive network activity, treat it as suspicious and perform a full malware scan. Always verify against your official Corsair iCUE installer.
Red Flags: If corsair-hid.exe is found outside Corsair directories, lacks a valid signature, has an unexpected file size, or shows unusual network activity or elevated privileges not required by iCUE, treat as suspicious and run a malware scan immediately.
Reasons it's running:
corsair-hid.exe is a core Corsair iCUE component that manages HID input/output for Corsair peripherals, enabling lighting, macros, and device discovery. It runs in the background to maintain real-time control over devices like keyboards and mice.
If installed from the official Corsair iCUE installer and located in Corsair directories, corsair-hid.exe is safe and expected. Validate its digital signature and location to ensure it is not impersonated by malware.
Yes, in some cases corsair-hid.exe or its integration with iCUE can spike CPU if profiles are complex, many devices are connected, or software updates conflict. A clean reinstall of iCUE and firmware updates usually resolves this.
Typical locations include C:\Program Files (x86)\Corsair\CORSAIR iCUE\Bin\corsair-hid.exe or C:\Program Files\Corsair\iCUE\Bin\corsair-hid.exe. Always verify the path matches official Corsair directories.
Disabling may disable lighting and macros. To disable safely, exit iCUE and stop the Corsair HID Service via services.msc, then prevent startup if desired. Re-enable by starting the service or launching iCUE.
If you suspect infection, run a full malware scan, verify the digital signature, and check if the binary resides in a Corsair directory. If signs point to tampering, remove the file and reinstall iCUE from Corsair's site.
