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.

Ignoring unauthorized copying
… Bill Gates said “And as long as they’re going to steal it, we want them to steal ours. They’ll get sort of addicted, and then we’ll somehow figure out how to collect sometime in the next decade.”
The practice allowed Microsoft to gain some dominance over the Chinese market and only then taking measures against unauthorized copies. In 2008, by means of the Windows update mechanism, a verification program called “Windows Genuine Advantage” (WGA) was downloaded and installed. When WGA detects that the copy of Windows is not genuine, it periodically turns the user’s screen black. This behavior angered users and generated complaints in China with a lawyer stating that “Microsoft uses its monopoly to bundle its updates with the validation programs and forces its users to verify the genuineness of their software”.

… the documents identified open-source software, and in particular the Linux operating system, as a major threat to Microsoft’s domination of the software industry, and suggested tactics Microsoft could use to disrupt the progress of open-source software.
