问题：我在哪里可以找到 Win10 升级日志以及如何解读它们？我尝试过三次升级，我想知道是否有任何我可以修复的问题，以便下次成功。特别是，如果失败是由不兼容的驱动程序、硬件错误、缺少文件或目录引起的，我可以尝试修复它。
细节： Windows 更新向我提供了 Win10 从 1909 版升级到 20H2 版的优惠。升级失败了两次，错误代码为 0x8007001f。然后 Windows 更新停止提供升级。因此，我第三次使用了升级助手，但升级再次失败。“失败”的意思是更新已安装，Windows 重新启动并完成安装，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。我找不到第三次尝试的任何日志，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，没有其他内容。我应该去别处看看吗？
中总共包含 450 行错误，但这可能是正常的setupact.log，C:\Windows\Panther\NewOs\Panther因为安装仍在进行中。大多数错误setuperr.log也出现在 中。我无法判断是什么错误导致安装停止并回滚。这些是最后的错误（包含几行重要的信息）：

升级失败是否由错误导致Store platform failed to find the user with ID: USER00000005, SID: S-1-0-0 (Nobody)？如果是的话，我必须等待微软的修复。

答案1
该问题是由 Windows 升级脚本中的一个错误引起的，该错误已存在多年，但仍然没有解决。它发生在用户配置文件不在系统磁盘上的计算机上。就我而言，我的系统磁盘是 C:，而用户配置文件在 D:。
要解决此问题，请打开 RegEdit 并导航到Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList。在这里，更改ProfilesDirectory为默认值C:\Users。就我而言，这足以使升级成功。升级成功后，请改ProfilesDirectory回以前的值。比较例如这里。
非常感谢@Ramhound！我希望微软能尽快解决这个问题，因为它给很多人带来了麻烦（试着在网上搜索一下）。
