A hacker named Clrokr has jailbroken Windows RT. He has found a way to bypass the security check on Windows RT, which means you would be able to run Metro and even desktop apps not signed by Microsoft. The apps must be ARM-based of course. Clrokr has actually found that Windows RT is the same as Windows 8. He says:

"They are the same thing and MSFT enforces Code Integrity to artificially separate these platforms... You can even enforce Code Integrity on Windows 8 to see what Windows RT feels like! The decision to ban traditional desktop applications was not a technical one, but a bad marketing decision."

The hack is not persistent beyond a reboot for now.

Read on his blog how he managed to find the bit in RAM which tells the OS whether they should run Unsigned  apps, Authenticode signed apps, Microsoft signed apps or Windows signed apps. By default Windows RT will only run Microsoft signed apps.

So Windows RT is basically Windows 8 running on ARM with desktop mode disabled! :D

I hope Microsoft won't block it. If Windows RT can run desktop apps then let Surface RT owners use them.

MS will changed it, but some one else, if not the same guy, will figure out what was changed.   And really, if this is made in to an app, all that you need to do is set it to run on windows start.  or compile it in to a service.


Pretty good stuff.

A Microsoft's spokesperson "applauded the ingenuity of the folks who worked this out and the hard work they did to document it," in a statement to The Verge today.


They are fixing it! -_-
