That is why the majority of the world's population who need a desktop or laptop will continue to use Windows, albeit in the form of pirated activation in more than 70% of cases.
Because there was and still is no real alternative to Windows, taking all factors into account.
M$ just needs to completely lose its reputation and any remaining trust (much like in the dollar), so that everyone rushes in a panic to look for other solutions.
This will only happen if M$ announces that it will stop developing Windows or remove compatibility with the entire x86 codebase. Why would they do this, cut the branch on which they (and the USA) are sitting globally? Moreover, I am 100% sure that Apple/Alphabet(Google)/M$/Intel/AMD/Qualcomm/Mediatek and other key companies are working closely with the NSA/CIA and in general with the US authorities to maintain geopolitical influence in the world through technological superiority and dependence on US technology. Therefore, even if the Indian Nadella decided to destroy Windows, he would simply be fired and kicked out, because it is not for him to decide these issues, but for the deep US authorities. As in the case of Intel and other key companies, they have not resolved any key issues for a long time without direct agreement with the US authorities or that top party in the US that really controls everything. This is only the appearance of independence of companies from the authorities; in reality, it has long been gone. Capitalism has long turned into imperialism for obvious reasons.
