In Gabe Aul’s blogpost (here) he says: Here are some known issues for this build We know this one will be a bit painful but there is a bug with this build in which Win32 (desktop) apps won’t launch from the Start menu. The workaround is to use search to find and launch these apps and pin them to your taskbar for quick access. Well, I have an easier work-around. All my apps on the start menu have a "Run as administrator" option if I right click on them. If I choose that they launch, but is I left click they don't.
