In a blog post , a Microsoft representative said unpatched versions of Windows will lose access to Windows Update next year due to the expiration of digital certificates used to verify their authenticity and connect to the company's update servers.
These certificates are set to expire on May 17, 2027 and June 19, 2027, affecting older versions of Windows 11, Windows 10, and Windows Server. Following these dates, the devices running the unpatched operating systems (OS) will no longer be able to access Windows Update.

微软的一位代表在一篇博客文章中表示,由于用于验证其真实性并连接到公司更新服务器的数字证书即将过期,未打补丁的 Windows 版本明年将无法访问 Windows 更新。
这些证书将于 2027 年 5 月 17 日和 2027 年 6 月 19 日到期,这将影响旧版本的 Windows 11、Windows 10 和 Windows Server。到期后,运行未打补丁操作系统 (OS) 的设备将无法访问 Windows 更新。
