Most code designed for computers with the x86 archetecture CPU in mind will need to be recompiled for your tablet’s ARM processor, but this can be done with a slightly modified version of Visual Studio 2012. Now that you have a jailbroken Windows RT tablet, capable of running unsigned desktop-style apps just like your computer, you’re going to need software to run on your tablet. If you’re seeing it a lot, wait two or three minutes before running the exploit. There aren’t many known issues with the jailbreak, but there’s one that might trip you up: if you run the exploit too early, before your tablet properly boots up then you might see the dreaded Blue Screen of Doom. Wait for runExploit.bat to finish and answer any prompts that appear on the screen. From a more technical aspect, Windows RT is actually the entire Windows OS rebuilt for use on ARM processors, which are what power almost all tablets, smartphones, and other gadgets. Press the volume Down button on your device.Ĥ. Windows RT is a sort of unique member of the Microsoft family of operating systems. Run runExploit.bat and wait about 20 seconds for the exploit to run.ģ. Boot up your tablet, and give the OS about a minute to load everything.Ģ. It’s not a huge deal–the process seems fairly straightforward:ġ. Unfortunately, because of secure boot, you will need to run the batch file every time you want to use desktop-style applications on your tablet. On RT devices, this policy (as stored in a UEFI variable) requires Microsoft-signed programs. Lacking the 'testsigning' or 'debug' boot parameter, the kernel takes the more-restrictive policy from the registry or UEFI. Follow all the instructions it gives you. The Windows kernel checks various sources (boot parameters, registry, and UEFI variables) for what signature level to enforce. The first time you run the program, an installer will pop up. Download the RT_Jailbreak-1.03.zip folder and extract it to a directory on your Windows RT tablet, such as the Desktop.ģ.
