You probably just want Express for Windows Desktop. Express for Web is for web development, Express for Windows Phone is for phone development, Team Foundation Server is more for team management stuff. Express for Windows 8 is more focused on developing Metro-style apps. Express for Windows Desktop is for traditional desktop-style apps, which is what SFML targets, and thus probably what you want.

I have 2010, If i download 2012 could i open 2010 project or most i manually build?

Something new with the express editions this year which is nice is that all three languages (c++, c#, VB) all come in the same IDE and do not have to be downloaded separately.

I noticed that many people have already provided the same answer I would which is "Express". Just wanted to chime in and say I agree all you need is express, also let me elaborate a bit more hopefully to help you understand what the true differences actually are.

In C++ you write code an run it through a compiler with potentially a slue of additional commands linking to external libraries and what not. As such you technically don't need an IDE (Such as Visual Studio), you just need to write your code and run it through the compiler with the correct command's. The reason that most if not all professional programmers choose to use an IDE is because it greatly simplifies the coding procedure through using intellisense (auto completion & popup tips), syntax highlighting (the colors) and allows you to point and click your settings that are later fed into the compiler as the proper commands.

With that said we get to the differences between professional and express versions of visual studio. Most simply, the express version is everything you need to code and compile your programs, it's ready out of the box. The pro versions allow you to install and use mod's and plugins that extend how the IDE itself works. In most cases they don't particularly make any difference to what you code or create. Examples would be like including SVN, Git or Preforce project collaboration. It can be nice to have some of these extra plugins, but if you can't afford or simply don't want to pay for pro... don't. It's not like your game itself will be any different if you make it with express or pro.

Good information Dan... except that you weren't really addressing the question being asked. The OP was trying to find out which express edition to install, the pro version was never on the table. Cornstalks gave a good summary of what the different flavours of express edition are for above.
