I use Windows when I have to now. I used to use Visual Studio as it is really good. But since Windows 8 and more so Windows 10 they have started taking from me. I paid for Windows 10 Pro, but I am subjected to the task of repeatedly removing software, or adverts for software, that I explicitly said remove. This is repeated when major updates go through. Plus the extra data and processing to get a system that isn't using my resources for tasks that I did not ask it too. It is my computer, not theirs.
So I dual boot and 99% of the time sit in Kubuntu land and my computer is fast, responsive, and generally only doing what I ask it too. As it should be.
Microsoft found a way to take an i7-7500 with 32GB of ram and make it feel slow on a fast OS. Windows 10 can be fast.
