我有一個腳本，它在 powershell 中使用 C# 程式碼來設定我正在為其開發 Windows 映像的裝置的螢幕解析度和方向。
由於各種原因（主要與螢幕方向相關），我選擇不使用 unattend.xml 中的設定。
在任何目標裝置上安裝映像後，當我啟動裝置並使用 unattend.xml 應答檔案完成 OOBE 時，我執行的腳本會執行，但傳回結果，表示它無法處理我的請求。
如果我隨後取得已完成的單元並在其上執行 sysprep 以將其設定為再次執行 OOBE，則腳本在第二次執行時會成功。
為什麼會這樣呢？
以下是 powershell/C# 腳本的程式碼。

第一次運行腳本時（在OOBE 嘗試1 期間），我執行其中一個SetDev*Resolution() 函數，並且“ChangeResolution()”函數返回：“無法處理您的請求。對此帶來的不便，我們很深表歉意。這告訴我，當我嘗試呼叫“ChangeDisplaySettings()”時，它失敗了。
執行此腳本時是否與沒有使用者有關？如果是這種情況，是否有解決方法，或者我是否需要找出其他方法？
