MS-DOS works for me.
Just another bloated O/S with a bunch of unnecessary crap.
I’m running a Dell Inspiron with a Core 2 Duo 2.0 Ghz CPU, 4 GB of Rams and WXP SP3, which recognizes 3.25 GB of RAM
I also run Avast AV, Malwareantibytes and Hit Man Pro and my PC is squeaky clean, no viruses, no Malware.
Also running Firefox as my Browser and using Ad Blocker Plus, Lightbeam and No Script.
My Brother is running Win 8.1 and the UI is a complete mess and difficult to navigate.
