I used XP for many years, Went to seven when XP was no longer supported. When Seven was dropped I went to 10. As a 62 Year old I have done some development work on DOS 3.0 various Windows platforms and appreciate the simplicity of Windows 10. However, I have run into older programs that 10 does not like. I have really come to like the "run as" options(compatibility mode) in Windows 10. Makes all the upgrades adapt to me for a change.
