Mo'slo has a windows interface and slows down both Dos and Windows programmes...
It has *four* ways of slowing the programmes and a choice of slowing everything or just one application/game, leaving the rest of the processes running normally.

So long as you have an intel-based CPU, it should work fine.
Pure NT OS is kinda not relevant. I trained in that and that was ages ago; it's not officially supported any more. Like Dos.

There's no need to slow down yr computer when using an emulator, as any emulator worth its salt will have some kind of mechanism for doing that built-in.
And, as a general rule, if the game needs slowing in windows you'll probably have other bugs to contend with too.
I try to avoid them.

If it's Mo'Slo's price-tag that's putting you off - you don't have to pay for software if you look hard enough in the right places.
Using some software as a trial is okay in my books. So long as, after a suitable trial period, if you continue to use the software: Buy a copy to say "thanks" to the developers.
