问题
I have installed Visual Studio 2013 Pro and then I wanted to install Windows Phone 8 SDK. But it installed Express Edition of VS 2012. Now if I delete VS 2013, what happens with my VS 2012? Can I delete it, because I don't have enough memory for it? Can you help me, please!

You can install this version of Visual Studio on a computer that already has an earlier version installed.
but
If you uninstall a version of Visual Studio on a computer that has more than one version installed, the file associations for Visual Studio are removed for all versions.

They are independent, you can uninstal one without influencing the other.
