>In the Programs & Features I have lots of MS Visual Studio different versions installed programs. I recently installed VS 2013 and I want to uninstall all prior versions of VS. However, there are so many entries in the Program and Features that I am wondering what should I chose to uninstall correct versions.

For me, when I want to upgrade, I always wanted VS to upgrade and not install and keep the old one in there. So, recently, I also had to go in there and remove VS 2012. I simply clicked on it and it uninstalled. I did not have any problem after. I continue to use VS 2013 and it works fine.
