• I think you are asking about reason of the suddenly appeared big window with green line inside. You grabbed splitter between these windows way up and now 3d Viewport is in the top. See blender.stackexchange.com/questions/5631/… – Mr Zak Sep 17 '16 at 18:57

If when you open Blender by default the layout is already messed up you may have to delete your Startup.blend file from the user preferences folder either under
• Blender/2.##/config for portable installations or under
• or %APPDATA%\Blender Foundation\Blender\2.##\config for formal installation, generally under C:\Users\<UserName>\AppData\Roaming\Blender Foundation\Blender\<VersionNumber>\config for Windows users
