What is rgb-controller-ui.exe?

rgb-controller-ui.exe is the graphical user interface component for Corsair iCUE's RGB controller. It provides color editors, lighting profiles, device grouping, and real-time synchronization across Corsair hardware. The UI pairs with a background service to apply settings to connected devices.

This UI runs alongside the iCUE backend service using IPC to apply color profiles, manage device groups, and render the lighting timeline. It does not directly drive hardware but issues commands through the service layer.

Quick Fact: rgb-controller-ui.exe coordinates with the iCUE service to push lighting changes to devices and to query device capabilities during profile edits.

Types of RGB Controller Processes

UI Process: Main user interface for editing lighting profiles and palettes
Driver/Device Communication Process: Interfaces with device drivers to apply colors and effects
Background Sync Process: Synchronizes settings with cloud or connected devices
Update Process: Checks for and downloads software updates
Logging Process: Records events and diagnostics for troubleshooting
Telemetry/Feedback Process: Optional data collection and usage telemetry

Is rgb-controller-ui.exe Safe?

Yes, rgb-controller-ui.exe is safe when it's the legitimate Corsair iCUE file installed from Corsair's official site.

Is rgb-controller-ui.exe a Virus or Malware?

The real rgb-controller-ui.exe is NOT a virus, but malware may masquerade with similar names to trick users.

How to Tell if rgb-controller-ui.exe is Legitimate or Malware

File Location:: Must be in C:\Program Files\Corsair\iCUE\rgb-controller-ui.exe or C:\Program Files (x86)\Corsair\iCUE\rgb-controller-ui.exe. Any rgb-controller-ui.exe elsewhere is suspicious.
Digital Signature:: Right-click the executable in Windows Explorer -> Properties -> Digital Signatures. Should show "Corsair Components, Inc." as the signer.
Resource Usage:: Normal usage is 2-15% CPU and 120-260 MB memory while actively editing profiles; constant high usage when idle is suspicious.
Behavior:: rgb-controller-ui.exe should run when iCUE is active or profiles are being edited; persistent background execution without iCUE is a red flag.

Red Flags: If rgb-controller-ui.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when iCUE isn't open, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately. Beware of similarly-named files like "rgb-controller-ui.bak" or "rgb-controller-ui.exe" from untrusted sources.

Why Is rgb-controller-ui.exe Running on My PC?

rgb-controller-ui.exe runs when Corsair iCUE is started or when you open the RGB controller UI to edit lighting profiles.

Reasons it's running:

Active RGB Control: You are editing lighting profiles or applying effects; the UI keeps the editor responsive and applies changes to devices.
Background Sync: iCUE may sync profiles across devices or with cloud services, keeping device lighting consistent.
Startup Program: iCUE is configured to launch at Windows startup, causing the UI to run in the background.
Device Discovery: The software detects connected Corsair devices and loads their current lighting state.
Update Checks: The application periodically checks for updates to profiles, firmware, or the iCUE software.

Can I Disable or Remove rgb-controller-ui.exe?

Yes, you can disable rgb-controller-ui.exe. Doing so will disable the Corsair iCUE RGB editing UI and may prevent real-time lighting changes until you re-enable or reinstall iCUE.

How to Stop rgb-controller-ui

Exit iCUE UI: Close the Corsair iCUE window and confirm all lighting changes are saved.
End rgb-controller-ui.exe: Open Windows Task Manager and end the rgb-controller-ui.exe process.
Disable Startup: Task Manager -> Startup tab -> Disable Corsair iCUE
Stop Background Features: In iCUE Settings -> General -> Disable 'Run at startup' or 'Start iCUE minimized'.
Uninstall (Optional): Windows Settings -> Apps -> Corsair iCUE -> Uninstall. Reinstall later if needed.

How to Uninstall rgb-controller-ui

✔ Windows Settings → Apps → Apps & features → Corsair iCUE → Uninstall
✔ Control Panel → Programs → Uninstall a program → Corsair iCUE → Uninstall
✔ Reinstall iCUE from Corsair's official website if you later need RGB control
