Win10升级到20H2版本失败——如何确定原因？

问题：在哪里可以找到 Win10 升级的日志以及如何解释它们？我已经尝试应用升级三次，如果有什么我可以解决的问题，我正在尝试获得线索，以便下次成功。特别是，如果故障是由不兼容的驱动程序、硬件错误、丢失文件或目录引起的，我可以尝试修复它。

详细信息： Windows 更新为我提供了从版本 1909 到 20H2 的 Win10 升级。升级失败 - 两次 - 错误为 0x8007001f。然后 Windows Update 停止提供升级。因此，我第三次使用升级助手，但升级再次失败。“失败”是指更新已安装，Windows 重新启动并正在完成安装，但最后一切都回滚了。（一轮大约需要一个小时。）

我能够在 中找到一些日志C:\Windows\Panther\NewOs，但这些日志仅来自第二次升级尝试。我在第三次尝试中找不到任何日志，它们似乎丢失/回滚了。在 Windows 事件日志中，只有一行：安装失败，错误 0x8007001f，没有别的。我应该去别的地方看看吗？

该setupact.log中C:\Windows\Panther\NewOs\Panther总共包含450个错误行，但这是作为安装继续正常的可能。大多数错误也都在 中setuperr.log。我不知道是什么错误导致安装停止和回滚。这些是最后的错误（有几个重要的信息行）：

升级失败是错误导致的Store platform failed to find the user with ID: USER00000005, SID: S-1-0-0 (Nobody)吗？在这种情况下，我将不得不等待 Microsoft 的修复。

编辑： SetupDiag 在C:\$WINDOWS.~BT\Sources\Panther. 它测试了很多东西，其中大部分是“不匹配”，不幸的是它什么也没找到。以下是内容SetupDiagResults.log：
