问题
A couple of days ago, I installed Visual Studio Express for C#; yesterday I installed Visual Studio Ultimate. Since I will no longer use the former, is it safe to uninstall it?

I uninstalled Visual Studio Express 2012 for Web right after having installed Visual Studio 2012 Ultimate and it still works perfectly. Also tried after a reboot, just to be sure.
