Microsoft hasn’t learned its lesson. If you click the “Check for Updates” button in the Settings app, Microsoft still considers you a “seeker” and will give you “preview” updates that haven’t gone through the normal testing process.
This problem came to everyone’s attention with the release of the October 2018 Update. It was pulled for deleting people’s files, but anyone who clicked “Check for Updates” in the first few days effectively signed up as a tester and got the buggy update. The “Check for Updates” button apparently means “Please install potentially updates that haven’t gone through a normal testing process.”
Michael Fortin, corporate vice president for Windows at Microsoft, explained that this is still going on in a blog post about Windows 10’s monthly update process on December 10, 2018:
微软Windows公司副总裁Michael Fortin解释说，这仍在关于Windows 10于2018年12月10日每月更新过程的博客文章中继续进行：
We also release optional updates in the third and fourth weeks of the month, respectively known as “C” and “D” releases. These are preview releases, primarily for commercial customers and advanced users “seeking” updates. These updates have only non-security fixes. The intent of these releases is to provide visibility into, and enable testing of, the non-security fixes that will be included in the next Update Tuesday release. Advanced users can access the “C” and “D” releases by navigating to Settings > Update & Security > Windows Update and clicking the “Check for updates” box. The “D” release has proven popular for those “seeking” to validate the non-security content of the next “B” release.
我们还将在每月的第三周和第四周发布可选更新，分别称为“ C”和“ D”版本。 这些是预览版本，主要针对商业客户和高级用户“寻求”更新。 这些更新仅具有非安全修复程序。 这些发行版的目的是提供对非安全修补程序的可见性并进行测试，这些修补程序将包含在下一个Update Tuesday版本中。 高级用户可以通过导航到“设置” >“更新和安全性” >“ Windows Update”并单击“检查更新”框来访问“ C”和“ D”版本。 对于那些“寻求”来验证下一个“ B”版本的非安全性内容的人来说， “ D”版本已被证明很受欢迎。
There it is in Microsoft’s own words. Fortin says “advanced users” can get the preview releases by clicking “Check for updates.” These updates would normally not be automatically installed until they’ve been tested. But, after you click the button, you’ve become a “seeker” and not a normal Windows 10 user.
用微软自己的话说就是这样。 Fortin说“高级用户”可以通过单击“检查更新”来获取预览版本。 这些更新通常必须经过测试才能自动安装。 但是，单击按钮后，您已经成为“搜索者”，而不是普通的Windows 10用户。
Once again, Microsoft is using everyone who clicks “Check for Updates” as a beta tester. Don’t click this button unless you want unstable updates. Your Windows 10 PC will automatically install updates as soon as they’re stable.
微软再次使用单击“检查更新”的每个人作为Beta测试人员。 除非您要进行不稳定的更新，否则请不要单击此按钮。 Windows 10 PC稳定后会自动安装更新。
At the very least, Microsoft needs to provide a warning before Windows 10 users click the “Check for updates” button. Don’t warn people in blog posts that only advanced users will read.
至少，Microsoft需要在Windows 10用户单击“检查更新”按钮之前提供警告。 不要在只有高级用户才能阅读的博客文章中警告人们。
As Woody Leonhard points out over at Computerworld, these extra monthly cumulative updates aren’t tested through the normal Windows Insider process. They’re just tested on your PC after you click the update. And Surface Book 2 owners have seen blue screen errors after installing these “optional” cumulative updates recently, so the stability of these updates is in real question.
