Visual Studio 2013 : how to open multiple projects in different windows?

Question

I'm trying to open two projects in two different windows but every time I double click an other solution, it closes the old project and then it opens the new project in that window. I mean I could do this with VS 2010 but with VS2013, I can't. How do you open multiple projects in different windows ?

EDITS: maybe I can't explain myself well. I want to open two different solutions in two different windows. this will make me able to work on many projects at the same time.

SOLVED:This issue disappeared as I reinstalled the OS!

For Windows 8: you just need to search for Visual Studio in the start menu, then right click and choose Open new window. It will open another instance of Visual Studio.

For Windows 10 and above: You need to right click of the Visual Studio on taskbar and click to program name(which is Visual Studio). It will open new instance of Visual Studio.
