Bjarne Stroustrup (the creator of C++) from his book "Programming -- Principles and Practice Using C++" C++ the language that Windows, Visual Studio, Office were written in. Most people compare the different versions of Windows based on appearance. I've heard many bad review of Windows 8 because it lacked the traditional start menu that everyone was used to (even though alternatives such as Start8 and Classic Shell are available). But Windows 8 did bring a lot of performance improvements of Windows 7, such as hybrid boot. Windows 8.1 also brought significant performance improvements over Windows 8. Currently I'm running Windows 10, because I always have to have the latest and greatest, but to tell you the truth I haven't seen any performance improvements, I haven't benchmarked it. What's your opinion of Windows 10 vs 8.1?
