*Some versions claim to support more than listed but to my current lnowledge, the above information is accurate. You can read about compatibility from Microsoft for 2015 2013 2012 2010 2008 and will find that nearly all new versions still claim to support Windows XP which is not the case in my experience.
If you are using Windows 7, Visual Studio 2015 will not install. In order to get Visual Studio for free, go here.
What do I need?
All you need is a Microsoft Account. If you already have a live or hotmail email address then you already have a Microsoft Account. If you do not have one, you will be prompted to sign up in order to get your free Visual Studio Express license key for installation. Visual Studio Express is always free and you will never need to pay Microsoft for it.
The whole process takes only a few minutes and gets you ready to write programs. Continue in order to learn about the Interface!
