What is bthprops-cpl?
bthprops.cpl is the Bluetooth Properties Control Panel applet in Windows. It provides a dedicated UI to view the Bluetooth radio state, manage paired devices, configure discovery visibility, and adjust power and security settings for Bluetooth peripherals. Accessed via Control Panel or Run (bthprops.cpl).
A CPL-based UI loaded by control.exe surfaces Bluetooth radio state, device management, and pairing controls via the Windows Bluetooth API and the bthserv service.
Quick Fact: The Bluetooth Properties panel coordinates changes with the system Bluetooth radio driver and services to reflect real-time device status.
Types of Bluetooth UI Processes
- Control Panel Applet: The main UI exposed by bthprops.cpl for Bluetooth configuration

How to Tell if bthprops.cpl is Legitimate or Malware
- File Location: Must be in
C:\Windows\System32\bthprops.cpl.
- Digital Signature: Right-click
C:\Windows\System32\bthprops.cpl -> Properties -> Digital Signatures; should show Microsoft Windows or Microsoft Corporation.
- Publisher Verification: Check the signer matches Microsoft Corporation.
- Resource Behavior: The CPL will not run in the background unless Bluetooth is active; unexpected background activity warrants a malware scan.
Red Flags: If bthprops.cpl appears outside System32, lacks a valid signature, or shows unexpected network activity, scan with Windows Defender or a trusted antivirus.
Why Is bthprops.cpl Running on My PC?
The Bluetooth Properties Control Panel runs when you open Bluetooth settings, connect devices, adjust discovery, or modify radio options. It coordinates with the Windows Bluetooth stack to present current device state and options.
Reasons it's running:
- User opens Bluetooth Properties: You clicked Bluetooth in Control Panel or Settings to view or modify paired devices and radio options.
- Bluetooth hardware changes: New Bluetooth hardware or drivers cause Windows to load or refresh the Bluetooth Properties panel.
- Device pairing or management: Initiating pairing, removing devices, or altering discovery triggers the UI.
- Radio state updates: Windows updates or power management policies may cause the panel to load to reflect changes.
- Background configuration tasks: Some system tasks refresh Bluetooth settings during startup or user session initialization.
Can I Disable or Remove bthprops-cpl?
Disabling the control panel item is not typical; you can disable Bluetooth via Settings, and you can avoid opening the CPL. Removing the CPL is not recommended as it’s part of the OS.
