You must be a Linux fan....   :-)   Knowing almost nothing about Windows....

The last version of Windows that was Dos based was Windows 95-98
Starting from Win NT,XP, etc. there is no more an underlying Dos layer...

And Windows 7 is even better. I have on my PC a triple boot, Win XP Pro,
64-bit Windows 7, and a special version of Debian Linux (Sidux).  
Each time I boot Linux I can observe, on the very same hardware, how much 
sluggish is its responsivness in the GUI, with respect to Win 7....

IMHO Linux is a great operating systems, as long as you use it for servers.
In that role it is maybe the best. But it won't ever win the desktop war...
when a window takes the double of the time to open than under Win 7, you feel
compelled to reboot with this last opsys.

Oh, BTW, I have also a laptop with only a 64-bit Win 7. This laptop does not
have a RESET  button, but I have never felt the lack of it.
