On Aug. 31, 2021, Microsoft announced that Windows 11, the first major upgrade in years and the latest version of its popular operating system, would become available on Oct. 5, 2021. The company says the system is faster and includes a redesign, new accessibility features, efficient input settings, a focus on hybrid work, and other features. The operating system is available as a free upgrade for eligible Windows 10 PCs. Windows 11 represents a shift from the company's previous stance of only updating an earlier operating system. Some tech reviewers say Window 11 is only an incremental improvement, pointing out that it lacks Android-app compatibility and other "game-changing features."
