Microsoft Windows RT Jailbroken. It happened. We all knew it was just a matter of time, now it looks like with a vulnerability in the Windows kernel that was ported to the RT platform allows unsigned desktop applications to run freely on the Windows 8 sibling, Windows RT.
The finding comes from a security researcher clrork at Surfsec, article that claims a method to enable a way to run ARM-based desktop applications in the (– now — not-so-limited) operating system, by exploiting a binary setting that restrict the environment only to Microsoft’s signed applications (Windows 8 apps and Office 2013 RT). Don’t get confuse here, only ARM compiled applications will work, not the traditional x86 (32-bit) desktop programs — This makes the jailbreak somewhat limited at this time –. Also if there was an easy set of instructions to do this, it will only last until the next reboot as the process can only be done in memory.
Windows RT is a clean port of Windows 8
According to Surfsec “Windows RT is a clean port of Windows 8″ [...] “The fact that this method works on Windows 8 as well shows how similar the systems are.”. And apparently there isn’t a technical limitation much as a marketing move from the company.
Another important thing to keep in mind, is that running ARM desktop apps will definitely impact the battery life of the device, which now is one of the strong points on getting one. In spite of that, the Pandora’s box is now open and expect ARM compiled applications (at least from freelancers) in the near future for Windows RT.

Update: In a new statement released to The Verge, Microsoft applauded the people involved jailbreaking Windows RT to run desktop apps. A spokesperson from the company said “applaud the ingenuity of the folks who worked this out and the hard work they did to document it”. Also the software giant admits that it is “not something the average user could, or reasonably would, leverage as it requires local access to a system, local administration rights and a debugger in order to work.”. But for those people wondering the future of this vulnerability, Microsoft has plans to release an update to mitigate the exploit.
