我在任务管理器上发现，当我试图启动VS2017的生产版本时，VS预览2019版本正在更新。以前从来没有这个问题。就像其他人建议的那样，我等了大约3分钟，问题平息了下来，没有产生重大影响。这种方式比通过任务管理器处理任务要好得多。: -)

我也有同样的问题。我的问题是VSIXAutoUpdate。我一直等到处理结束。您可以在任务管理器(Ctrl + Alt + Del)中看到VSIXAutoUpdate。 VSIAutoupdate有时可能是一个恶意软件，所以你必须检查任务管理器中的属性中的详细信息(右键单击VSIXAutoUpdate)。 你可以看到下面的网页:

原因是一个待定的Windows更新。Windows更新后，Visual Studio启动没有任何问题。

很可能Visual Studio正在更新，就像错误消息暗示的那样，如果你等待几分钟更新完成，你应该能够再次运行Visual Studio而没有问题。

If the problem persists or if you're just curious, open up your task manager and see if there is anything related to (Microsoft) Visual Studio running but don't just kill the process. Check instead if the process is using any resources - if it has a high I/O count, then it's actually updating and you should let it do its thing. If CPU-usage and memory usage remain mostly constant and there is no disk activity for the process for several minutes, this could mean that the process is stuck. You might have to kill it, but proceed with caution. Hopefully if this is an update for Visual Studio, the process name should include a version number or some sort of indication of what kind of update is being applied that you can use to search for more information through a search engine or through Microsoft's online resources.

我已经打开visual studio安装程序，单击修改，并启动visual studio。这解决了问题。

我从Windows任务管理器中启动了Windows安装程序服务，然后打开了Visual Studio 2019 (这里建议的解决方案对我来说很有效)
