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.
Microsoft has openly encouraged piracy as far back as the 90s. I remember an interview with Gates where he said as much.
This has been part of Microsoft’s business model, especially for Windows and Office for 30 years. They actively encouraged pirating the software to ensure it cemented itself as the defacto standard in homes and offices with a view that one day users would have no choice but pay for it. For over 20 years now this has been part of the bigger desktop-as-a-service goal.
Soon businesses and home users will have no choice but to remotely log into a Windows system that is hosted in a datacentre and provided by Microsoft or one of their partners. Local installs will be a thing of the past. Think Citrix Presentation Server and thin clients which is where this whole idea started a long time ago.
Nah that’s just for high security government systems, if you run a small business or something you might not want to fuck around with thin clients unless you’re working directly with big databases and stuff
