Ive seen some problems with it - it was stuck (after 8 hours+ - left it overnight) on installing a Visual Studio 2012 update, and didn't reset (again, it got stuck on the animated circles).
Another computer took over an hour to install everything, and reset was slow. Haven't tried the third computer yet.
It does make you wonder if these patches are being fully tested...
