20H1

20H1 refers to a semi-annual feature update for Microsoft's Windows 10 operating system. The designation "20H1" signifies the year and the half of the year in which the update was released, specifically the first half of 2020. This update, officially named Windows 10 version 2004, introduced a variety of new features and improvements aimed at enhancing user experience, productivity, and system performance. Key additions included improvements to the Windows Search functionality, enhanced Cortana integration, and a new optional Windows Sandbox environment for testing applications in isolation. The update also brought refinements to the Windows Hello facial recognition system and introduced a cloud-based download option for resetting the PC, allowing users to download a fresh copy of Windows instead of relying on locally stored files. As with all major Windows 10 updates, 20H1 underwent a period of testing through the Windows Insider Program before its general release to the public. This phased rollout ensured stability and allowed Microsoft to gather feedback before wider deployment. The update was made available to all Windows 10 users through Windows Update.
