Region code How to remove the region code?

With Windows XP and above and most DVD players today users do have the option to change their DVD region scheme a few times (often no more than four times). To adjust the region in Windows follow the below steps.

1. Click Start, Settings, and open Control Panel
2. Double-click the System icon.
3. In the System Properties click the Hardware tab.
4. In Hardware click the Device Manager button.
5. In Device Manager click the "+" symbol next to the DVD/CD-ROM drives icon.
6. This should expand and display each of the drives installed in your computer. Double-click the DVD drive you wish to change the region for.
7. In the Properties window click the DVD Region tab.
8. Within this window you should be able to change your region code and also be able to see how many changes remaining you have on the drive.
