immutability

"Immutable" operating systems are designed with a read-only core that is updated comprehensively, allowing user data and applications to exist independently from the base system, reducing risks of corruption and configuration drift. While macOS is largely immutable, Windows cannot transition to an immutable model due to its design based on mutability, which allows for continuous modification and backward compatibility. Windows 11's flexibility leads to a cumulative change model, making it increasingly difficult to troubleshoot and maintain. Microsoft has made some improvements within the mutable framework, but challenges remain, such as dependency control and application integration. Users expect seamless updates, but Windows is perceived as high-maintenance, leading to performance issues. A truly immutable version of Windows would conflict with user expectations and require significant software rewrites. Consequently, Windows is likely to remain in a hybrid state, adopting some immutable features while still facing issues related to its mutable architecture.
