我有一个脚本，它使用 powershell 中的 C# 代码来设置我正在为其开发 Windows 图像的设备的屏幕分辨率和方向。
由于各种原因，主要与屏幕方向有关，我选择不使用 unattend.xml 中的设置。
在任何目标设备上安装映像后，当我启动设备并使用我的 unattend.xml 应答文件让 OOBE 完成时，我拥有的脚本会运行，但返回一个结果表明它无法处理我的请求。
如果我随后获取完成的单元并在其上运行 sysprep 以将其设置为再次运行 OOBE，则脚本将在第二次运行时成功。
为什么会这样？
这是 powershell/C# 脚本的代码。

脚本第一次运行时（在 OOBE 尝试 1 期间），我执行了 SetDev*Resolution() 函数之一，并且“ChangeResolution()”函数返回：“无法处理您的请求。抱歉给您带来不便。”这告诉我，当我尝试调用“ChangeDisplaySettings()”时失败了。
这可能与运行此脚本时没有用户有关吗？如果是这种情况，是否有解决方法，还是我需要找出另一种方法？
