Microsoft will cease support for Windows 10 in October 2025, meaning new security vulnerabilities will not be patched, increasing exposure to threats. Cybercriminals are expected to target Windows 10, which still has over 60% market share, making it an attractive target. ESET estimates that around 32 million PCs in Germany are still using Windows 10. Users can opt for the Extended Security Updates program for an additional cost, extending updates until October 2026, or use 0Patch for updates until 2030. Windows 10 IoT Enterprise LTSC 2021 will receive updates until 2032, but its use as an office PC is restricted. Users are encouraged to upgrade to Windows 11 where hardware compatibility exists for ongoing security updates and new features.
