✨ AI Insight

Microsoft Windows continues to dominate the desktop and laptop market with about 66 percent share, keeping the personal computer firmly a Windows platform decades after its launch. Apple's macOS is a distant second at roughly 12 percent, its share limited by Apple's premium pricing and closed hardware ecosystem. Desktop Linux, long championed by enthusiasts, holds under 4 percent, while Google's ChromeOS, strong in education, reaches just over 1 percent. The clear gap between Windows and everything else illustrates how entrenched Microsoft's position remains in workplaces and homes, even as computing has shifted heavily toward mobile devices. The dominance of a single operating system on traditional computers stands in sharp contrast to the more balanced competition seen on smartphones.
