Windows 10 was a significant advancement for Microsoft, introducing features like Cortana, a digital assistant, and Windows Hello, a biometric security feature. It celebrated its tenth anniversary but is set to retire in October 2025, with Microsoft ending support for it. Despite the rise of Windows 11, which faced criticism for its TPM 2.0 security requirements, Windows 10 maintained a strong user base until recently. Additional features included the Action Center and the Xbox App, while some elements from Windows 8 persisted. Cortana was designed to enhance user interaction, but Windows 11's changes have been viewed as less inclusive, impacting users with older PCs.
