Yeah, I've been following the XDA "jailbreak" almost from its inception. My first thought after I heard the RT desktop was going to be restricted was "I hope somebody finds a way around that". I'm not a serious coder so I don't understand some of the more complex debugging they posted, but I got enough to know I wouldn't have been able to come up with that on my own that's for sure. I totally agree, the signing requirement should be something we as end users can change, maybe via group policy or even a registry change would be better. We shouldn't have to hack it to be able to run Windows programs!!

That's what I've been saying. Microsoft made some really bone-headed decisions with Windows on ARM. It should have just been a simple recompile of Windows 8/8 Pro. That would have been so much better. A big thanks to the fine folks at XDA developer forums for figuring out how to change the executable signing requirement, and for all the work they've done recompiling win32 apps for ARM. Their work has made my Surface RT so much more useful. Actually, I wouldn't have bought it otherwise. Some .NET 4 apps just work unmodified. Unfortunately there is no guarantee MS won't patch what makes this "jailbreak" work in the future. That'd be a sad day.
