I can use Windows without major problems, but I'm puzzled by how slowly some parts of it seem to improve. Microsoft is a huge company, so why doesn't it produce an operating system that matches Linux or macOS in areas like memory usage, responsiveness, native system tools, and battery life? Apple sometimes introduces major redesigns with new releases, while Windows can take years to replace old dialogs and interfaces. Is this mainly caused by technical limitations, organizational priorities, or the need to preserve compatibility?

The biggest reason is compatibility. Windows has to keep supporting an enormous range of old business applications, hardware, drivers, scripts, and undocumented behaviors. Many organizations depend on software that was written decades ago, so replacing the operating system underneath it is much riskier than it looks. That legacy support is a major advantage for businesses, but it also leaves Windows with layers of old and new systems running side by side.
Microsoft’s priorities also shift according to where it earns the most recurring revenue. Cloud services, enterprise products, security, and AI have often received more attention than making the desktop lighter or more elegant. Large organizations also value predictability, long support periods, and controlled change, so a completely redesigned system could create more problems for customers than it solves. The sluggishness is partly a technical consequence of legacy support and partly a deliberate business trade-off.
Apple has much tighter control over its environment: it designs the hardware, controls the supported configurations, and can retire old APIs or architectures on its own schedule. Microsoft has to support computers from many manufacturers, countless peripherals, and a much wider variety of business setups. Linux avoids some of this by leaving more integration and troubleshooting to distributions, vendors, or users. Windows is expected to work for almost everyone out of the box, which makes radical changes harder.
Apple’s transitions also tend to be prepared years in advance. Developers may first be pushed away from older APIs, and then the hardware change happens after much of the difficult cleanup is already done.
There’s also a difference between visual change and actual development speed. Microsoft has made plenty of major changes to security, virtualization, deployment, hardware support, and cloud integration, but those improvements aren’t always visible on the desktop. At the same time, different Windows components have different histories and teams, so replacing an old dialog or subsystem can involve more risk than simply designing a new screen.
That said, Windows can still feel inconsistent because newer interfaces are often layered over older control panels and system components instead of replacing them completely.
A government or enterprise application can still be critical even when the people who built it have retired. If it continues working, replacing it may be far more expensive and dangerous than tolerating an outdated interface.
