You probably know it already that there is something called as Registry in your pocket pc like in your desktop pc, a database for the OS to store some configuration settings. The manufacturers however disable certain features of the OS with simple registry settings. You can also change most of the features or the way the device acts by tweaking these registry settings. So we planned to collect the various known registry hacks for your pocket pc and compile it in a single page.

Disclaimer:  The following are suggestive modifications to the registry database of your pocket pc. Editing the registry settings are extremely risky if not done perfectly. If you want them to be done safely, consider using our software Registry tweaker PRO
