Blu-ray Players Region
Here you can change region settings of popular Blu-ray players (PowerDVD, WinDVD, TMT) with a single click. It makes your playback software essentially "region free" or more accurately "multi-region".
We will use PowerDVD software as example, which comes with a feature that allows for 5 modifications of the region code, and after the fifth alteration the code is fixed according to the last alteration, the manufacturer of PowerDVD may not decide to release a patch to make it multi-region. Unless some third party has created their own such patch (or crack) and you can find Passkey is one of those utilities which offers the easiest way of overcoming this restriction.
You can also reset region in the tray context menu. See the illustration as below.
