I was 38 before windows 95 existed...and have used EVERY MS OS since Dos 4 [and later messed with older things from the first windows and Dos] as a standard/primary OS.
The only one that didn't exist [for me] as a daily user was Vista....as it was released too early for its own good...and did not have drivers available for my DSL Modem connectivity...so it remained dead in the water until 7.
I have no issues changing OS GUIs .... being one of [not all that many] those here that used alternative shells as an every-day standard....and there have been many of those, not 'just' Litestep.
There's one called Calmira.... gives you a GUI from [eg] XP to re-shell your Windows 3.11.
There are 3rd party Dos GUIs [shells] I used to use...eg. Gorin.
I do not have an issue at all with DIFFERENT interfaces.....as long as they have actual inherent practicality.
8 does not.
Its kernel is better than 7's ....but its shell belongs on an idiot mobile phone, not without third party help [which it shouldn't need if MS had got it right in the first place].
