如果您目前使用其中一个操作系统，我们建议将操作系统升级到 Windows 10 或 Windows 11 以避免中断。对于不符合 Windows 10 或 Windows 11 操作系统升级系统要求的计算机，您可以通过手动将文件上传到 Web 上的 OneDrive 来备份和保护文件，并继续在所有设备上访问、编辑和共享您的文件。
网友@b1k3rdude表示：部分用户有很多原因不想或不需要升级，并提醒微软忘记了 Windows 8.1 在延长支持到 2023 年 1 月，因此，这一操作是微软迫使用户使用较新的操作系统的另一个明显举措。

微软《End of support for OneDrive desktop application on Windows 7, 8, and 8.1》原文
In order to focus resources on new technologies and operating systems, and to provide users with the most up-to-date and secure experience, beginning January 1, 2022, updates will no longer be provided for the OneDrive desktop application on your personal Windows 7, 8, and 8.1 devices.
Personal OneDrive desktop applications running on these operating systems will stop syncing to the cloud on March 1, 2022.
After March 1st, 2022, your personal files will no longer sync and should be uploaded/accessed directly on OneDrive for web.
If you are currently using one of these operating systems, we recommend upgrading your operating system to either Windows 10 or Windows 11 to avoid disruption. For machines that do not meet system requirements for Windows 10 or Windows 11 operating system upgrade, you can back up and protect your files by manually uploading them to OneDrive on the web, and continue to access, edit, and share your files on all your devices.
If you are using the OneDrive desktop application for business, starting January 1, 2022, support for this application will be aligned with the Windows support lifecycle.
Note: Windows 7 and Windows 8.1 are in extended support until January 10, 2023. Windows 8 reached end of support on January 12, 2016.
