Windows as a software package would have never been affordable to individuals or local-level orgs in countries like India and Bangladesh (especially in the 2000’s) that are now powerhouses of IT. Same for many SE Asian, Eastern European, African and LatinoAmerican countries as well.
Had the OS been too difficult to pirate, educators and local institutions in these countries would have certainly shifted to Linux and the like. The fact that Windows could be pirated easily is the main factor that led to its ubiquity and allowed it to become a household name. Its rapid popularity in the '00s and early ‘10s cemented its status as the PC operating system. It is probably the same for Microsoft Office as well (it is still a part of many schools’ standard curricula).
The fact that Windows still remains pirateable to this day is perhaps intentional on Microsoft’s part.
PTSD…
I once destroyed a CRT monitor by misconfiguring X11.
Nowadays Linux just works to the point where my 72 year old mother is able to deal with Pop_OS without issue.
But man, those early days of unstable drivers, slow dial-up internet, and navigating through Usenet and IRC for decent support was a nightmarish labor of love.
The silky smoothness that we have now was built on caffeine and the backs of millions of greybeards.
(For the record: “Greybeard” is a nerdy term of endearment that I’ve seen adopted by people identifying all across the rainbow. Kinda like dwarfs on Discworld).
Greybeard is also the name for an experienced DRG player
