Running Desktop Applications on Windows RT
clrokr have figured out how to run desktop apps on Windows RT by modifying a single byte sized hardcoded global variable in the kernel (both Intel and ARM).

Microsoft, please consider making code signing optional and thereby increasing the value of your Windows RT devices!
