Core Viewpoint - Microsoft plans to end free security updates for Windows 10 on October 14, 2025, which will increase vulnerability to malware and cyber attacks for users who do not upgrade to Windows 11 [1][3]. Group 1: Windows 10 Lifecycle - Windows 10 has a service life of ten years, from its release in 2015 to the end of updates in 2025, making it one of the most successful operating systems after Windows XP and Windows 7 [3]. - As of August 2025, approximately 46.2% of global users are still using Windows 10, with an estimated 200 million to 400 million devices unable to upgrade to Windows 11 due to hardware requirements [13]. Group 2: Upgrade Challenges - Microsoft has set high hardware requirements for Windows 11, including the necessity of a TPM 2.0 chip, which many older devices lack, making them ineligible for the upgrade [4][5]. - Users who do not wish to upgrade to Windows 11 may need to purchase new devices, as the current hardware may not support the new system [6]. Group 3: Extended Security Updates (ESU) - Microsoft offers a paid Extended Security Update (ESU) service for Windows 10 users, allowing them to pay $30 (approximately 213 RMB) for an additional year of security updates, with a maximum purchase of three years until October 2028 [7][8]. - The ESU service requires users to have a Microsoft account, which has been a point of contention for many Windows 10 users reluctant to upgrade [9]. Group 4: User Reactions and Criticism - The policy has sparked dissatisfaction among users, with consumer advocacy groups like "Consumer Reports" publicly urging Microsoft to extend the free security update period for Windows 10 [10][11]. - Critics argue that Microsoft's approach is contradictory, promoting Windows 11 for enhanced security while leaving Windows 10 users vulnerable once updates cease [13]. Group 5: Office Suite Support Termination - Microsoft will also terminate support for Office 2016 and 2019 on October 14, 2025, meaning no more security updates or technical support will be provided for these versions [15][17]. - Users are encouraged to migrate to Microsoft 365, a subscription-based service that offers continuous updates and enhanced security features, or to upgrade to Office LTSC 2024 for offline use [18].
