I left my computer to the upstairs and when I go back, it locked itself.

However, there are some drawbacks

Despite being secure, Dynamic Lock has some issues that would affect your experience when working. These are some problems that I discovered when this feature is on.

  • The Bluetooth speaker stopped playing after a few seconds — I still able to connect to the Bluetooth speaker, but the music I played always stop unintentionally. Apparently, the PC has to “ping” my phone every several seconds to track its location which causes interruptions with other Bluetooth devices.
  • The computer stays locked when you back — Unfortunately, Dynamic Lock only locks the computer when you are away, but not unlock it when you come closer to it.
  • You cannot set the distance — How far exactly until the computer will lock? You will never know and you have no option to set the distance.

Despite these issues, Dynamic Lock could be the best method for you to keep your computer and its data safe from unauthorized access.

Other than that, there is also an automatic locking system that will lock the computer by a timer. Check out my previous guide about How to Lock Windows Automatically When Not in Use.
