如何在 Windows 11 中重設 Windows 更新

本指南將向您展示如何在Windows 11中將 Windows 更新元件和政策完全重設為預設值。

Windows Update 透過自動下載和安裝 Microsoft 發佈的最新更新、驅動程式和修復程式來讓 Windows 11 保持最新狀態。

有時您可能會遇到 Windows Update 問題，例如無法下載或安裝更新、錯誤訊息、無法搜尋新更新、掛起的更新問題等。當 Windows Update 資料庫或元件被停用時，可能會出現這些問題。損壞、一項或多項與Windows 更新相關的服務未運作等。

重設 Windows 更新元件通常可以解決這些類型的問題。

以下是在 Windows 11 中重設 Windows 更新的方法：

1. 下載下面的.bat 檔案。

Code:

If "%1"=="%Variable%" (echo. &echo. Please right-click on the file and select &echo. "Run as administrator". &echo. Press any key to exit. &pause>nul 2>&1& exit)
cmd /u /c echo Set UAC = CreateObject^("Shell.Application"^) : UAC.ShellExecute "%~0", "%Variable%", "", "runas", 1 > "%temp%\getadmin.vbs"&cscript //nologo "%temp%\getadmin.vbs" & exit
