Overview
- Microsoft begins delivering the first extended security patches on November 11 to Windows 10 PCs in the EU, EEA and Switzerland that enroll in the free one‑year ESU.
- Devices that are not registered stop receiving automatic security updates following the October 2025 support cutoff.
- The October update KB5066791 for Windows 10 version 22H2 is required for the ESU activation option to appear in Windows Update.
- Users can attempt to open the registration screen with the Run command ms-settings:windowsupdate-esu if the setting does not show up in the interface.
- Ashampoo’s free Windows 10 ESU Login tool checks for missing services or components and attempts fixes to restore the enrollment UI, with PC‑WELT examining additional root causes.
