With the release of a new tablet, I'm inclined to wonder how similar it is to other tablet devices, specifically those by Google and Apple. Is privilege escalation possible on a Surface? What I'm referring to is the equivalent process of Jailbreaking on iOS devices, and Rooting on Android devices. Or is the Surface more like a desktop OS, where privilege escalation is the simple matter of knowing the admin password?
At the moment, no. In the future, possibly. Places you might want to keep your eye on:

There is a Jailbreak tool for Windows RT 8.0.
But none for 8.1 so far. It seems like the one developing a Jailbreak for RT 8.1 stopped working on 8.1 months ago and started working on Windows 10 instead now.
So I hope, there will be a Jailbreak for RT 8.1 soon.
