Tablets that run Windows RT are currently limited to apps from the Windows Store. Thanks to a new jailbreak exploit, however, the operating system has been tweaked to let devices run unsigned ARM-based desktop apps. A forum member at XDA-Developers has packaged the exploit into a simple batch file, which is able to bypass certain restrictions put in place by Microsoft (MSFT). There are a few catches, however. The jailbreak can only be changed in memory, requiring the batch file to be run each time the device is powered on. In addition, traditional desktop programs designed for x86-based processors will still be incompatible with Windows RT devices and must be recompiled for the ARM architecture. The exploit does open the operating system up to the homebrew community, though.
