在这篇文章中，我们将了解Windows操作系统中的 wuauserv 进程，并了解如何修复Windows 11/10/8/7CPU或内存^(Memory)使用问题。该服务的名称是Windows Update Service，我们将了解如何轻松停止或重新启动Windows 服务^{(Windows Service)}。

什么是wuauserv

wuauserv进程或Windows 更新服务^{(Windows Update Service)}可以检测、下载和安装Windows和其他程序的更新。如果禁用此服务，此计算机的用户将无法使用Windows Update或其自动更新功能，并且程序将无法使用Windows Update Agent ( WUA ) API。

其可执行文件的路径是C:\WINDOWS\system32\svchost.exe -k netsvcs。它通常在svchost.exe中消耗最多的^{(svchost.exe)}CPU资源和内存，这本身是正常的，但有时它会异常消耗资源。在这种情况下，您可以尝试以下方法。

修复 wuauserv 高 CPU 使用率

1]运行系统维护疑难解答^{(Run System Maintenance Troubleshooter)}

运行系统维护疑难解答。运行系统维护疑难解答^{(System Maintenance Troubleshooter)}。打开Run，键入以下内容并按 Enter 键：

它有帮助吗？

2]运行系统性能疑难解答^{(Run System Performance Troubleshooter)}

接下来，运行系统性能疑难解答^{(System Performance Troubleshooter)}。为此，请打开提升的命令提示符^{(Command Prompt)}，键入以下内容并按Enter以运行性能疑难解答^{(Performance Troubleshooter)}。

msdt.exe /id PerformanceDiagnostic

此疑难解答程序可帮助用户调整设置以提高操作系统速度和性能。

3]运行Windows更新疑难解答^{(Run Windows Update Troubleshooter)}

运行Windows 更新疑难解答^{(Windows Update Troubleshooter)}。Windows 10 用户可以通过设置中的疑难解答页面访问所有疑难解答^{(TRoubleshooters)}。

4]重新启动Windows更新服务
