How to Lock and Unlock a PC with USB Drive?

Do you want to Lock and Unlock a PC with USB Drive? PREDATOR locks your PC when you are away, even if your Windows session is still active. It uses a regular USB flash drive as an access control device. PREDATOR helps to limit the time your kids spend on their computers. You define the times of day when each user may access the computer with the built-in scheduler. You can make specific rules for each user and each day of the week. Out of authorized periods you can either lock the desktop, logoff the user or shutdown the computer or you can remove the flash drive to disable the computer for good.

Advanced Security Features

  • PREDATOR can protect several PCs with the same USB flash drive, e.g. your home and office computers.
  • PREDATOR can protect several user accounts on a PC, each one having its own settings and its own USB stick.
  • PREDATOR can lock user accounts according to an hourly, daily or weekly schedule, each one with its own timetable.
  • PREDATOR can send alert messages by Email.
  • PREDATOR can take pictures of the person who tries to use your computer and attach them to an email or upload them to a remote server.
  • Photo Monitoring : PREDATOR can take pictures with your webcam continuously (time interval is configurable), even when the keyboard and the mouse are inactive. Picture files are stored in a folder, or exported by email or ftp.
  • PREDATOR records all security-related events in a log file: start, alarms, stop. By reading this log, you will know if intruders have tried to use your computer while you have been away.
  • PREDATOR frequently changes the security codes recorded on your USB drive. If an intruder manages to copy your stick, this copy will not work because the codes on your own stick will have changed in the meantime.
  • PREDATOR protects its own in-memory process. Nobody can stop it with Ctrl-Alt-Del.
    PREDATOR disables the CD Autorun feature in Windows, to prevent intruders from running malware on specially crafted CDs.
  • PREDATOR lets you regain control of your computer if you lose your stick: when you start the software for the first time, you set a password that will unlock your session if your USB drive is not available.
  • PREDATOR can sound an audible alarm if somebody enters an invalid password.
  • PREDATOR can protect a self-running PowerPoint presentation: it will lock the keyboard and the mouse while keeping the presentation visible on the screen.
  • PREDATOR can prevent unauthorized users from working with the computer after booting in Safe Mode.

Change USB Format

You must use an exFAT or a FAT32 formatted flash drive. If your USB Stick is in NTFS format then you must reformat it in exFAT or FAT32. To Check or Reformat USB, do below simple steps:

#1: Go to Windows Explorer

#2: Right Click on your USB Drive

#3: Select Format

#4: In pop up box, Select File System to FAT32 or exFAT

#5: Click Format

Make sure that there is no any important file in USB otherwise it will get deleted.

NTFS formatted flash drives are not suitable for PREDATOR because they require that you use the “Safely remove hardware” dialog of Windows before you disconnect them.
If you unplug them without using this dialog, you will end up with corrupted data.


#1: Download PREDATOR from below link and Install in your System


#2: Insert USB and Run PREDATOR
