Windows RT is configured to run only Signed Applications inside it, however a team of Software crackers managed to create a backdoor against its restrictions inside windows to run Unsigned Applications.
Thus allowing the RT to be Jailbreaked. XDA Developers user “netham45” has released a batch file that does the entire jailbreaking process automatically, so it modifies the Windows RT system kernel without user interaction.
Even though the software developer admits that some users might get a BSOD after launching the application, he says that everything should work just fine on all Windows RT tablets, including Microsoft’s Surface RT.
Microsoft has already confirmed the jailbreak, saying that it “applauds the ingenuity” of the software developers behind the project, but also hinted that a future fix could block their attempts to modify the system kernel.
Explaining further, Microsoft would have a very hard time trying to block their efforts. “They can patch it through Windows Update, but since we have the ability to reinstall from recovery partitions we can revert any Windows Updates they release.
