Support for Windows 10 officially ended in October 2023, with Microsoft focusing on Windows 11. Users can receive security updates for Windows 10 until 2027 through a paid option or a free method that requires linking a OneDrive account and activating cloud backup. Windows 10, launched in July 2015, still holds over 53% of the market share as of May 2025. The free cloud backup option comes with a 5GB storage limit, which may require users to subscribe for additional storage if backups exceed this limit. Microsoft offers a program for Extended Security Updates, allowing users to ensure updates continue through October 14, 2027, and businesses can purchase up to three additional years of updates.
