I need Visual Studio 2013 for my computer science class and I'm wondering if the upgrade to Windows 10 will affect how it runs in any way.
I used VS 2013 (Standard) on my Windows 7 machine, and upgrading to Windows 10 made no difference in how it behaved or acted. It works just like it did before. But since I don't use every single part of VS, I'll issue a "Your Mileage May Vary" warning. :)
For more anecdotal evidence, perhaps check out this Reddit thread: Has anyone used Visual Studio 2013 on Windows 10 TP?, where practically everyone says "works for me".
As Insane mentioned in his comment, if you're worried about OS compatibility, then you should use a newer version of VS. But since this of a for learning in a class, check with your instructor before you do that, as there may be mild differences that may affect you following instructions meant for an older version.
