One of the downsides to Microsoft’s ARM-powered Windows RT operating system is the lack of desktop applications. While Windows RT devices to retain the traditional Windows desktop, only Microsoft applications that come pre-packaged with Windows are allowed to run. Instead, Microsoft wants users to stick to Modern UI applications and the Windows Store to get new apps. (Granted, the ARM hardware powering these devices necessitates porting x86 desktop applications in order to run in the first place, but Windows RT locks out even recompiled apps).
Enthusiasts are working on changing that, however. A XDA Developers forum member known as Netham45 recently released a tool that allows users to run unsigned desktop applications on Windows RT. The new RT Jailbreak tool is a batch file that automates a hack discovered by another hacker known as clrokr.
The hack is currently only temporary, and needs to be redone after every computer restart. It does, however, allow Windows RT to run unsigned code on the desktop. After downloading the batch file, you run the runExploit.bat and follow the prompts. After it completes, you users can run recompiled desktop apps such as PuTTY, 7-zip, TightVNC, DOSBox, Quake 2, and more.
While it is not a permaent solution, it is a step in the right direction, and makes ARM-powered Windows RT devices a lot more interesting and useful to power users. For more information on the RT Jailbreak hack, and to grab the batch file to unlock your WinRT tablet, check out this forum thread on the XDA Developers website.
