如何修复无法检索用户 IIS 的组信息 APPPOOL\DefaultAppPool
How to fix Can't retrieve group information for user IIS APPPOOL\DefaultAppPool
在Windows10 Visual Studio中使用社区版。 ASP.NET MVC 4 应用程序 运行 使用由 Visual Studio 安装的 IIS Express 在调试模式下从它获得。
升级到 Windows 10 周年纪念版失败并出现错误
0xc1900101 - 0x30018
安装在 FIRST_BOOT 阶段失败，在 SYSPREP 操作期间出现错误。
Windows setuperr.log 文件如下。
日志中的最后一行包含
Can't retrieve group information for user IIS APPPOOL\DefaultAppPool.
是升级失败的原因。
如何解决这个问题？可以删除或修复 Visual Studio IIS APPPOOL\DefaultAppPool 帐户，以便 Visual Studio 继续工作。
我没有在 Visual Studio 或其他地方找到任何 GUI。

我会说这是 并非每个 Windows 错误都是问题,
IIS APPPOOL\DefaultAppPool是一个虚拟用户，在系统中并不真正存在，以这个用户名作为参数调用Win32 API函数NetUserGetLocalGroups总是失败，因为它找不到那个用户，因为它是一个虚拟的。
因此，虽然 Windows 更新过程将此报告为错误，但我很确定这不是您的更新不起作用的问题。再次查看日志以找到罪魁祸首。
顺便说一句，据我所知，IIS APPPOOL\* 用户没有在 Visual Studio 附带的 IIS Express 中使用。它们仅由适当的 IIS 使用，在某些时候您必须在系统上安装该 IIS。我认为删除 IIS 中的应用程序池 DefaultAppPool 不会从系统中删除对该虚拟用户的所有引用。
在Windows10 Visual Studio中使用社区版。 ASP.NET MVC 4 应用程序 运行 使用由 Visual Studio 安装的 IIS Express 在调试模式下从它获得。

我会说这是 并非每个 Windows 错误都是问题,
IIS APPPOOL\DefaultAppPool是一个虚拟用户，在系统中并不真正存在，以这个用户名作为参数调用Win32 API函数NetUserGetLocalGroups总是失败，因为它找不到那个用户，因为它是一个虚拟的。
因此，虽然 Windows 更新过程将此报告为错误，但我很确定这不是您的更新不起作用的问题。再次查看日志以找到罪魁祸首。
顺便说一句，据我所知，IIS APPPOOL\* 用户没有在 Visual Studio 附带的 IIS Express 中使用。它们仅由适当的 IIS 使用，在某些时候您必须在系统上安装该 IIS。我认为删除 IIS 中的应用程序池 DefaultAppPool 不会从系统中删除对该虚拟用户的所有引用。
