BtProx v1.5.0

BtProx (Bluetooth Proximity Lock Utility) is a small freeware utility that will lock your computer if a Bluetooth device, such as a mobile phone, goes out of range.

First you pair your machine with a Bluetooth device, ideally your mobile phone. When the connection is lost to the mobile phone, BtProx will lock the computer after a certain period of time. It can also run a single application/command to coincide with the lock, such as a script to dismount network drives.

The program sits in the Windows system tray and will popup a tooltip baloon if the connection to the Bluetooth device is lost.

The tool is freeware and has been tested with every version of Windows since 2000.
