12 月 24 日消息,Windows Update 是 Win11 系统中的核心组件,负责通过网络下载和安装 Windows 更新。如果你的 Windows Update 服务突然从计算机中丢失怎么办?本期 Win11 学院就来介绍下修复这个问题的一些方法。
的网友们,如果你遇到 Windows Update 从你的设备上丢失,那么可以尝试下以下几种方式。(前面 3 种方式为常规方式,在修复 Windows Update 更新错误的文章中已有介绍,这里就简单复制一下)
-
运行 Windows 更新疑难解答
-
运行 SFC 和 DISM 扫描
-
扫描恶意软件
-
通过注册表编辑器手动恢复 Windows Update 服务
-
重置你的电脑
运行 Windows Update 疑难解决
网友使用系统内置的疑难解答工具来修复 Windows Update 丢失问题。这个工具能检测、诊断和解决任何潜在的系统更新问题,确保你的计算机顺利和安全地运行。
网友可以按照以下步骤进行:
1. 按下键盘上的 Win 键和 I 键组合快捷方式,打开设置应用(用户也可通过开始菜单等其它方式进入设置应用)
2. 在左侧选择“系统”,右侧选择“疑难解答”
3. 选择“其他疑难解答”
4. 找到“Windows 更新”,点击右侧的运行
整个疑难解答过程可能需要一段时间,完成上述步骤后,网友可以再次尝试在 Windows 上安装更新。
运行 SFC 和 DISM 扫描
网友可以通过 SFC 和 DISM 方式解决这个问题。SFC(系统文件检查器)扫描将检测任何损坏的系统文件并试图修复它们,而 DISM(部署映像服务和管理)扫描检查任何需要修复的损坏 Windows 组件。
这两种扫描都是相对快速和直接的过程,不需要任何高级技术知识。网友所需要做的就是以管理员身份打开命令提示符,并按照以下步骤操作:
1. 打开开始菜单,然后搜索 CMD,右键以管理员身份运行命令提示符
2. 在跳出的窗口中输入“sfc /scannow”命令,按下回车键
3. 在保护区域选择“病毒和威胁保护”
4. 点击“扫描选项”,然后选择“完全扫描”选项之后,点击“立即扫描”
如果您使用任何其它杀毒软件,它应该有一个类似的方法来扫描您的电脑上的问题。您可以清理和删除任何威胁,并在检测和处理这些威胁之后重新启动您的电脑。
通过注册表编辑器手动恢复 Windows Update 服务
导致 Windows Update 丢失的一个原因可能是弄乱了某些注册表文件。如果是这种情况,您可以尝试通过编辑 Windows 注册表手动恢复 Windows Update 服务。网友需要注意的是,修改注册表可能会存在一定的风险,在确定操作之前请做好备份。
1. 按下 Win 键打开开始菜单
2. 在搜索框中搜索“regedit”(不需要完整输入),然后点击“注册表编辑器”
3. 打开“计算机 \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services”路径
4. 这个列表会很长,找到“wuauserv”项,如果没有找到的话,直接跳过到第 9 步。
5. 右键“wuauserv”项,然后选择“导出”,保存到电脑上
10. 然后将以下代码复制到记事本中
