我在Mac安装Win10 双系统的时候，当时选择了 Windows 10 Pro 1607 这个版本。目前根据微软官方的说法，这个版本的Windows 需要更新到Windows 10 1709这个版本。
If you're currently running Windows 10 Version 1507, Version 1511, Version 1607 or Version 1703, you can expect to receive a notification that states that your device has to have the latest security updates installed. Windows Update will then try to update your device.
When you receive the update notification, click Update now to update your device.
This update is also offered directly to Windows Update Client for some devices that have not installed the most recent updates.
Windows 10 Version 1507 and Version 1511 are currently at "end of service." This means that devices that are running these operating systems no longer receive the monthly security and quality updates that contain protection from the latest security threats. To continue receiving security and quality updates, Microsoft recommends that you update the system to the latest Windows version, Windows 10 Version 1709.
Windows 10 version 1607 and version 1703 are not yet at "end of service." However, they must be updated to the latest versions of Windows 10 to ensure protection from the latest security threats.
To learn more about the "end of service" status for these versions of Windows 10, see the frequently asked questions for Windows 10 Version 1507 or Windows 10 Version 1511.
而用BootCAMP安装的Windows10 不知道有什么Bug，无论如何都无法正常更新。而通过关闭Windows Update无法解决微软的强制更新，他会不断地安装一个补丁，然后安装 Windows 10 Update Assistant 这个流氓软件。手动卸载后一起重启他又会回来。
而只需要点上你不想要的那些补丁，然后点击下一步，即可屏蔽Windows 10 Update Assistant。
