AxCrypt will not differ from the operating system versions. So we can see the same user interface and features in windows 7 and 10. AxCrypt will be same in both windows versions.
If you go for mac os, then also you will get same features with slightly different user interface.
Nope, AxCrypt do not have an option to create a hidden operating system. Because it is a file encryption software. It will help us to secure our files.
