Windows RT is basically what you get if you port Windows 8 to run on ARM-based processors and then prevent the operating system from running any third party apps that aren’t found in the Windows Store. But it turns out you can trick the operating system into running unsigned apps loaded from other locations.
Website On The Surface of Technology has posted details of a method to Circumvent the code integrity check, which lets you install any Windows app compiled to run on an ARM-based processor.
Unfortunately, most Windows apps aren’t designed for ARM chips. So even if you do manage to get around Microsoft’s security measures using this exploit, you probably won’t find many apps to install… at least not yet.
Theoretically developers could write new desktop-style apps that would run on Windows RT tablets and other devices, or port existing software. But it’s not clear if there are enough Windows RT devices in the wild for it to be worth anyone’s time to do that.
You’ll also need to re-jailbreak your device every time you reboot, which can be a bit of a hassle.
Still, it’s always fun to see hackers figuring out how to make devices a little more open than the manufacturer had intended.
