Compared to iOS, Chrome OS, and even Android, Windows is a powerful platform that lets users install almost anything and do anything they need to get things done. Microsoft, however, has had the ironic problem that it has trouble locking Windows down and selling it that way to businesses and schools. Not that it didn't try but it has repeatedly failed before finally reaching a compromise in Windows 10 in S Mode. Given that history and the company's flip-flopping policy, users may have started panicking when they couldn't get out of S Mode. The good news is that it's apparently just a bug. The bad news: Microsoft still hasn't fixed it yet.
