Microsoft will officially terminate support for products such as Office LTSC 2021 on October 13, 2026. It is recommended that users upgrade to Microsoft 365 or Office 2024. Since it is not possible to continue services through the official paid Security Update Extend (ESU) program, third-party security company 0patch has announced a non-official patch solution. This solution provides critical security patches that can be applied without restarting the computer, and it promises to maintain maintenance for at least three years after Microsoft stops supporting these products. The 0patch Enterprise package is designed for medium and large enterprises. The annual subscription fee is 34.95 euros per computer (approximately 273 yuan), and it also covers security patches for other Windows versions that have been discontinued. 0patch emphasizes that its services only include security repairs and technical support, and it does not provide comprehensive official technical support.
