Microsoft will conclude security support for Windows 10 in October 2025. Users can opt for a one-year extended security update for a fee or utilize a free cloud backup solution linked to their OneDrive accounts. Windows 10 remains the most widely adopted Windows operating system, with over 53% of installations as of May 2025. Microsoft will roll out the Extended Security Updates (ESU) wizard in July 2025, allowing users to enroll and receive updates until October 13, 2026. Businesses can purchase up to three additional years of updates. Users are entitled to 5GB of complimentary OneDrive storage, but backups may exceed this limit, necessitating a paid plan for additional space.
