重置 SoftwareDistribution^{(Reset the SoftwareDistribution)}和Catroot2 文件夹^{(Catroot2 folders)}，看看它是否对您有帮助。

为此，请打开记事本并复制并粘贴以下文本 -

创建批处理文件后，转到保存的位置并右键单击该文件。此后^(Thereafter)，从上下文菜单中选择以管理员身份运行。^{(Run as administrator)}

如果UAC对话框出现在屏幕上，只需点击Yes按钮授予管理权限。

这将启动命令提示符并立即开始重置Windows 更新^{(Windows Update)}组件。

3]运行系统文件检查器^{(Run System File Checker)}和DISM工具

4]重置^(Reset)Windows更新^{(Windows Update)}组件

重置 Windows 更新组件^{(Reset the Windows Update Components)}，看看是否适合您。

按Win+R键盘快捷键打开“运行”^(Run)对话框。在文本字段中，键入cmd，然后按Ctrl+Shift+Enter快捷键。这将以管理权限打开命令提示符。

在提升的命令提示符窗口中，键入以下命令 -

net user administrator /active:yes

在这里，您需要退出^(Sign)您的Windows。为此，请按Ctrl ^(Sign)Ctrl+Alt+Del键盘快捷键并从相应页面中选择退出选项。

此后，使用新的管理员^{(Administrator)}帐户重新登录。

检查问题现在是否已解决。

6]手动安装更新

或者，您可以尝试通过从Microsoft 更新目录^{(Microsoft Update Catalog)}手动下载并安装所需的更新^{(downloading and installing the required update manually)}来解决此问题。

我希望本指南中的内容可以帮助您修复这个烦人的错误代码。^{(I hope something in this guide may helps you to fix this annoying error code.)}
