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.

对于VS2019上的相同问题，清除%temp%文件夹对我有用。

尝试检查任务管理器并杀死任何与Visual Studio相关的进程(任何版本)。

更新: 正如许多人在评论中提到的，最好等一段时间，直到这些过程自己结束

我发现“缓解”痛苦的唯一方法是打开win 10任务管理器，右键单击VSIXAutoUpate.exe，在上下文菜单中选择进入详细信息，右键单击VSIXAutoUpate.exe，再次在上下文菜单中选择设置优先级并选择实时......正如我所说，这是为了减轻痛苦，而不是结束痛苦

解决方案:不要只是打开任务管理器并杀死vsautoupdate .exe正在更新的所有进程，这将在您尝试启动Visual Studio时出现问题，因为更新未完成。相反，等待更新完成，这是当你启动Visual Studio。如果你不再需要定期更新的Visual Studio组件，同样建议通过Visual Studio安装程序卸载该组件

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。
