如果您在Windows PC 上查看此页面，那么您已经依赖多个系统进程将您带到这里。顶部是Windows系统内核 ( ntoskrnl.exe )，它允许软件与您的 PC 硬件交互。像Chrome^(Chrome) (chrome.exe)这样的低级应用程序使用内核来显示这样的页面。

不幸的是，并非每个应用程序和系统服务都是可靠的。错误、安全漏洞和高CPU使用率很常见，依靠定期的Windows 更新^{(Windows updates)}来修复。具有讽刺意味^(Ironically)的是，Windows Update本身可能会通过waasmedic等相关服务导致^(waasmedic)CPU和RAM使用率过高。这是你需要知道的。

什么是 Windows 上的 Waasmedic 服务？^{(What Is the Waasmedic Service on Windows?)}

wassmedic服务（也称为Windows ^{(wassmedic )}Update Medic 服务^{(Windows Update Medic Service)}和Wassmedicagent.exe）是处理部分Windows 更新^{(Windows Update)}进程的后台系统服务。Waasmedic负责保护Windows 更新^{(Windows Update)}不被禁用或处理不当（例如，流氓恶意软件感染^{(rogue malware infections)}）。

如果您（或其他人）尝试禁用Windows Update，则 wassmedic 进程将进行干预以阻止它。如果任何与Windows 更新^{(Windows Update)}相关的系统进程被禁用，wassmedic 将重新启动它们。您不能轻易禁用它，因为这样做会绕过Windows 10中^{(Windows 10)}Windows 更新^{(Windows Update)}的内置保护。

如果您担心这个过程，请不要担心——它完全合法，是帮助您的 PC 正常运行的必要组件的一部分。您的 PC 上正在运行的 wassmedic 或Windows 更新^{(Windows Update)}进程不太可能是真正的交易，但如果您不确定，请务必检查可能的恶意软件^{(check for possible malware)}。

是什么导致 Waasmedic 高 CPU、RAM 和其他系统资源使用率？^{(What Causes Waasmedic High CPU, RAM, and Other System Resource Usage?)}

Windows不太可能在没有正当理由的情况下调用这个小的可执行文件。^{(executable file)}如果您在任务管理器中看到 waasmedic（或^{(Task Manager)}Windows 更新^{(Windows Update)}）报告CPU、RAM或其他系统资源使用率过高，则表明Windows 更新^{(Windows Update)}存在问题，可能需要进一步调查和故障排除。

这是因为Windows Update Medic 服务^{(Windows Update Medic Service)}（正式称为 wassmedic）是一项监控PC 上整体Windows Update服务“健康状况”的服务。^{(Windows Update)}如果Windows 更新^{(Windows Update)}遇到问题，waasmedic 将尝试修复它。例如，如果它意外停止，它可能会重新启动Windows 更新。^{(Windows Update)}

如果 waasmedic在任务管理器中报告^{(Task Manager)}CPU使用率过高，则表明幕后正在发生某些事情。小幅增加是意料之中的，但如果您发现CPU使用率长时间处于高位，则应按照以下步骤检查Windows 更新是否正常工作。^{(Windows Update)}

大多数用户甚至可能根本看不到 waasmedic 出现在任务管理器^{(Task Manager)}中。如果一切正常，则该过程可能仅在执行操作（例如修复Windows 更新^{(Windows Update)}）时出现。

如何在 Windows 上对 Waasmedic 进行故障排除^{(How to Troubleshoot Waasmedic on Windows)}

Windows 更新^{(Windows Update)}是 wassmedic 流程的重点。如果您看到 waasmedic 报告CPU使用率过高或其他问题，这几乎肯定与您 PC 上的Windows 更新问题有关。^{(Windows Update)}

值得庆幸的是，您可以按照一些常见的故障排除步骤来解决此问题。首先^(First)，您应该（在第一个实例中）检查Windows 更新^{(Windows Update)}是否正常工作并且所有可用的更新都已安装。如果您仍然遇到问题，则可以使用内置工具检查系统的运行状况。

检查 Windows 更新是否正常运行^{(Check Windows Update is Running Properly)}

要检查Windows 更新^{(Windows Update)}是否正常工作，您需要执行以下操作：

1. 右键单击^{(Right-click)}开始^(Start)菜单并选择设置^(Settings)。

1. 在“设置”^(Settings)菜单中，选择“更新和安全”^{(Update & Security )} > “ Windows 更新”^{(Windows Update)}。如果Windows 更新^{(Windows Update)}工作正常，Windows将搜索并提示您安装任何可用的更新。按照^(Follow)屏幕上的任何其他说明执行此操作。

1. 如果Windows 更新^{(Windows Update)}不起作用，请右键单击开始^(Start)菜单并选择运行^(Run)。

1. 在“运行”^(Run)框中，键入services.msc，然后选择“确定^(OK)”进行确认。

1. 在“服务^(Services)”窗口中，滚动并找到Windows Update和Windows Update Medic Service。如果这些服务未运行，请右键单击每个服务并选择Start。否则，请右键单击每个服务并选择重新启动^(Restart)。

1. Windows 更新^{(Windows Update)}服务运行后，返回 Windows 设置中的Windows^{(Windows Settings)}更新菜单^{(Windows Update)}并检查新更新。如果系统正常工作，waasmedic 应该恢复到正常的系统资源使用水平（通常极低）。

使用 DISM 和 SFC 修复 Windows^{(Repair Windows with DISM and SFC)}

如果您无法修复Windows Update，或者有问题阻止您重新启动Windows Update系统服务，则您的Windows系统文件可能已损坏。Windows包括称为^(Windows)DISM和SFC的内置工具，可帮助您修复此问题，但您需要使用Windows PowerShell才能使用它们。

如果您想修复Windows系统文件，您需要执行以下操作：

1. 首先，您需要打开一个新的PowerShell窗口。右键单击^{(Right-click)}开始^(Start)菜单并选择Windows PowerShell (Admin)来执行此操作。

1. 在新的 PowerShell 窗口中，键入dism.exe /Online /Cleanup-image /Restorehealth并选择Enter键。按照^(Follow)屏幕上的任何其他说明进行操作。

1. 一旦DISM工具清理了您的内置Windows系统映像，您就可以使用它来修复您的Windows系统文件。为此，请键入sfc /scannow并选择Enter。

等待一段时间让SFC扫描完成并在完成后重新启动您的 PC。Windows将自动修复任何损坏或丢失的文件。但是，如果您仍然遇到问题，您可能需要考虑扫描恶意软件^{(scanning for malware)}或完全重置 Windows^{(resetting Windows)}，以确保您的Windows安装稳定且没有错误。

如何禁用 Windows Update Medic 服务^{(How to Disable the Windows Update Medic Service)}

Windows Update是Windows 10中几个受保护的系统服务之一。与早期版本的Windows不同，您无法阻止Windows 更新^{(Windows Update)}检查或安装重要更新。无需额外交互即可安装这些更新对您的 PC 安全至关重要。

这意味着如果不使用粗略且不可靠的软件，您将无法完全禁用 waasmedic 服务。虽然确实存在第三方工具来禁用它，但我们不建议您尝试它们，因为我们不能保证它们可以安全使用。

禁用Windows 更新^{(Windows Update)}还会导致系统不稳定，并使您的 PC 面临安全问题。但是，您最多可以暂时^{(temporarily)}禁用Windows 更新^{(Windows Update)}35 天。这将限制 waasmedic 的系统资源使用，允许您对其任何问题进行故障排除。

如何临时禁用 Windows 更新^{(How to Temporarily Disable Windows Update)}

1. 要暂时禁用Windows 更新^{(Windows Update)}（并减少 waasmedic 系统资源使用），请右键单击开始^(Start)菜单并选择设置^(Settings)。

1. 在“设置”^(Settings)菜单中，选择“更新和安全”^{(Update & Security )} > “ Windows 更新”^{(Windows Update)} > “高级选项^{(Advanced Options)}” 。

1. 在“高级选项”菜单中，使用“^{(Advanced Options)}暂停更新”^{(Pause Updates )}下拉菜单选择您希望暂停所有更新的时间。您所做的任何更改都将立即生效。

暂时禁用Windows 更新后，与^{(Windows Update)}Windows 更新^{(Windows Update)}（包括waasmedic ）相关的所有系统进程将保持非活动状态，直到恢复更新的日期过去或直到您手动重新启用Windows 更新。^{(Windows Update)}

保护您的 Windows 10 电脑^{(Protecting Your Windows 10 PC)}

如果您担心Windows PC 上的^(Windows)Windows Update Medic 服务^{(Windows Update Medic Service)}(waasmedic) ，请不要惊慌。它是合法的，并且作为保护Windows 更新^{(Windows Update)}免受中断的一种方式。虽然您可以使用第三方工具禁用Windows 更新^{(Windows Update)}，但我们不建议您这样做，尽管您可以停止个别更新^{(stop individual updates)}。

waasmedic 服务可以提供帮助，但它并不能解决所有问题。如果Windows 更新不会安装新更新^{(Windows Update won’t install new updates)}，您可以使用一些常见的故障排除步骤进行故障排除，尤其是在更新卡住^{(updates get stuck)}的情况下。如果一切都失败了，请不要忘记您可以擦除并重置 Windows^{(wipe and reset Windows)}以在之后恢复您的 PC。

What is the Waasmedic Service and Is It Safe?

If yоu’re viewing this page on a Windows РC, then you’re already relying on severаl system processes to get you here. At the top is thе Windows system kernel (ntoskrnl.exe) which allows software to interact with your PC hardware. Lower-level applications like Chrome (chrome.exe) use the kernel to display pages like this one.

Unfortunately, not every application and system service is reliable. Bugs, security holes, and high CPU usage are common, relying on regular Windows updates to fix. Ironically enough, Windows Update itself can cause high CPU and RAM usage through related services like waasmedic. Here’s what you need to know.

What Is the Waasmedic Service on Windows?

The wassmedic service (also known as the Windows Update Medic Service and Wassmedicagent.exe) is a background system service that handles part of the Windows Update process. Waasmedic is responsible for protecting Windows Update from being disabled or mishandled (by, for example, rogue malware infections).

If you (or something else) tries to disable Windows Update, the wassmedic process will intervene to stop it. If any system processes related to Windows Update are disabled, wassmedic will restart them. You can’t easily disable it, as doing so bypasses the built-in protection for Windows Update in Windows 10.

If you’re worried about this process, don’t be—it’s entirely legitimate and forms part of the necessary components to help your PC run properly. It’s improbable that the running wassmedic or Windows Update processes on your PC are anything but the real deal, but if you’re unsure, make sure to check for possible malware.

What Causes Waasmedic High CPU, RAM, and Other System Resource Usage?

Windows is unlikely to call upon this small executable file without good cause. If you see waasmedic (or Windows Update) report high CPU, RAM, or other high system resource usage in Task Manager, it’s a sign that Windows Update is having trouble and might require further investigation and troubleshooting.

This is because the Windows Update Medic Service (as wassmedic is officially known as) is a service that monitors the “health” of the overall Windows Update service on your PC. If Windows Update runs into issues, waasmedic will attempt to repair it. It may restart Windows Update if it stopped unexpectedly, for instance.

Should waasmedic be reporting high CPU usage in Task Manager, it’s a sign that something behind-the-scenes is happening. A small increase is to be expected, but if you’re seeing high CPU usage over a prolonged period, you should check if Windows Update is working properly by following the steps below.

Most users may not even see waasmedic appear in Task Manager at all. If everything is working, the process may only appear when an action (such as repairing Windows Update) is being performed.

How to Troubleshoot Waasmedic on Windows

Windows Update is the focus of the wassmedic process. If you see waasmedic reporting high CPU usage or other issues, it’s almost certainly related to a problem with Windows Update on your PC.

Thankfully, there are some common troubleshooting steps you can follow to resolve this. First, you should (in the first instance) check if Windows Update is working and all available updates are installed. If you’re still having trouble, you can then use built-in tools to check the health of your system.

Check Windows Update is Running Properly

To check if Windows Update is working properly, here’s what you’ll need to do:

1. Right-click the Start menu and select Settings.

1. In the Settings menu, select Update & Security > Windows Update. If Windows Update is working properly, Windows will search for and prompt you to install any available updates. Follow any additional on-screen instructions to do this.

1. If Windows Update isn’t working, right-click the Start menu and select Run.

1. In the Run box, type services.msc, then select OK to confirm.

1. In the Services window, scroll through and locate Windows Update and Windows Update Medic Service. If these services aren’t running, right-click each service and select Start. Otherwise, right-click each service and select Restart instead.

1. Once the Windows Update services are running, return to the Windows Update menu in Windows Settings and check for new updates. If the system works, waasmedic should return to normal levels of system resource usage (typically extremely low).

Repair Windows with DISM and SFC

If you can’t fix Windows Update, or there’s a problem preventing you from restarting the Windows Update system services, your Windows system files may be corrupted. Windows includes built-in tools called DISM and SFC to help you repair this issue, but you’ll need to use the Windows PowerShell to use them.

If you want to repair your Windows system files, here’s what you’ll need to do:

1. First, you’ll need to open a new PowerShell window. Right-click the Start menu and select Windows PowerShell (Admin) to do this.

1. In the new PowerShell window, type dism.exe /Online /Cleanup-image /Restorehealth and select the Enter key. Follow any additional on-screen instructions.

1. Once the DISM tool has cleaned up your built-in Windows system image, you can repair your Windows system files using it. To do this, type sfc /scannow and select Enter.

Allow some time for the SFC scan to complete and restart your PC once it’s done. Windows will automatically repair any files that are corrupted or missing. But if you’re still having issues, you may need to consider scanning for malware or resetting Windows entirely to ensure your Windows installation is stable and free of errors.

How to Disable the Windows Update Medic Service

Windows Update is one of several protected system services in Windows 10. Unlike earlier versions of Windows, you can’t stop Windows Update from checking or installing important updates. It’s considered critical for your PC’s security for these updates to install without additional interaction.

This means that you can’t disable the waasmedic service completely without using sketchy and unreliable software. While third-party tools do exist to disable it, we wouldn’t recommend you try them as we can’t guarantee that they’re safe to use.

Disabling Windows Update can also cause system instability and will leave your PC exposed to security issues. However, you can temporarily disable Windows Update for up to 35 days. This will limit system resource usage for waasmedic, allowing you to troubleshoot any problems with it.

How to Temporarily Disable Windows Update

1. To disable Windows Update temporarily (and reduce waasmedic system resource usage), right-click the Start menu and select Settings.

1. In the Settings menu, select Update & Security > Windows Update > Advanced Options.

1. In the Advanced Options menu, select how long you wish to pause all updates using the Pause Updates drop-down menu. Any changes you make will apply immediately.

Once Windows Update is temporarily disabled, all system processes relating to Windows Update (including waasmedic) will stay inactive until the date for resuming updates passes or until you re-enable Windows Update manually.

Protecting Your Windows 10 PC

If you’re worried about the Windows Update Medic Service (waasmedic) on your Windows PC, don’t panic. It’s legitimate and included as a way to protect Windows Update from interruption. While you can use third-party tools to disable Windows Update, we don’t recommend it, although you can stop individual updates.

The waasmedic service is there to help, but it doesn’t fix everything. If Windows Update won’t install new updates, you can troubleshoot using some common troubleshooting steps, especially if the updates get stuck. If all else fails, don’t forget that you can wipe and reset Windows to restore your PC afterward.
