Users on Windows 10 are experiencing persistent upgrade reminders following the August 2025 Patch Tuesday update (KB5063709), which includes a full-screen banner encouraging them to upgrade to Windows 11. This pop-up appears after updates are installed and indicates that support for Windows 10 will end on October 14, 2025, after which users will not receive technical support or security updates. Users can choose to dismiss the alert, but it will reappear, along with options to download or schedule the installation of Windows 11. Microsoft has updated its documentation urging users to make a decision before the end-of-life date. After October 14, 2025, Windows 10 will receive only two updates, and users can extend updates until October 13, 2026, by using the 'Enroll now' button on the Windows Update page, though this option may not be available to all users. It is recommended that users save a copy of the Windows 10 ISO before the end-of-life date.
