我正在使用可选的 Windows 10 功能“统一写入过滤器”(uwfmgr.exe) 来保护自助服务终端机器免受不必要的更改。现在,为了部署自定义更新,它包含一个服务用户,可以在该用户下对受保护的卷进行更改。
C:\Windows\system32\UwfServicingMasterScript.cmd
为了执行这些自定义更新,应该编辑脚本。(官方文档)
现在我无法编辑此文件,因为它归“TrustedInstaller”用户所有,而该用户的管理员也没有权限。
我这里遗漏了什么?我应该更改此文件的所有者吗?

我自己对这个问题的理解并不完整,但我相信在进行这类更新时你应该使用一定的程序,特别是你不应该拥有 Windows 文件的所有权。
文章中更好地描述了这个过程 Microsoft UWF(统一写入过滤器)概述,其中有一个简短的摘要:
启用 UWF 后,创建一个新的文本文件,例如
C:\TestPersist
使用以下命令将其添加到 UWF:
uwfmgr file add-exclusion c:\testpersist
使用以下命令启用 UWF:
uwfmgr filter enable
要检查 UWF 设置,请使用:
uwfmgr.exe get-config
参考:
注意:您可能会发现 Windows 10 的新功能 Windows 沙盒。

我可能有点迟到了,但我刚刚发现了这篇文章,因为我遇到了同样的问题。
通过使用 @vomit-it-chunky-mess-style 的评论,我得到了以下 C# 代码,该代码可用于将 cmd 文件替换为我自己的。希望这可以帮助下一个到达这里的人。
using System.Diagnostics;
var masterScriptLocation = @"C:\Windows\System32\UwfServicingMasterScript.cmd";
var newMasterScript =
