Windows 11/10/8/7解决的最棘手的问题之一是当您看到 100%磁盘使用^{(Disk Usage)}消息并且您的 PC 突然停止响应或响应缓慢时。虽然可能有很多原因，但通常是在任务管理器中^{(Task Manager)}Disk Usage is at 100%时引起的。这篇文章还可以帮助您面对持续的高 CPU 或高内存使用^{(high CPU or high Memory usage)}问题。

磁盘、CPU、内存使用高峰

任务管理器^{(Task Manager)}中的100%磁盘^(Disk)、高 CPU^{(High CPU)}、高内存^{(High Memory)}使用率

在本指南中，我们介绍了在学习和实施其他人讨论的方法以及我们自己的实验后解决上述问题的分步过程。许多论坛也提到了禁用Superfetch、Prefetch和BITS服务等方法，但我们不建议这样做。我的意思是你可以真正禁用什么和多少来解决问题！

如果您遇到此类问题，这里有一些故障排除步骤可以帮助您解决问题。首先创建一个系统还原点，然后浏览整个列表并决定您要尝试哪一个或多个建议。

1. 卸载第三方浏览器
2. 运行 Chkdsk
3. 在Windows Defender^{(Windows Defender)}中禁用基于云的保护
4. 禁用 Windows 搜索索引器
5. 禁用打印后台处理程序服务
6. 调整视觉效果
7. 更新设备驱动程序
8. 运行 SFC 和 DISM
9. 运行性能疑难解答
10. 升级您的固件或升级您的 RAM
11. 使用刷新 Windows 工具
12. 检查系统健康报告
13. 使用 Process Tamer 进行故障排除
14. 是否启用了消息信号中断？^{(Message Signaled Interrupt)}
15. 关闭^(Turn)设备上的Windows写入缓存缓冲区刷新

由于原因可能很多，因此解决方案可能很多 - 所以首先查看整个列表，看看哪些可能适用于您的情况。

1]卸载第3方浏览器

使用控制面板^{(Control Panel)}，卸载所有浏览器——当然除了Edge和Internet Explorer。这是为了隔离插件的问题。另一个建议是从每个浏览器中逐个删除插件并进行测试。Adobe Flash和Shockwave Player是常见的罪魁祸首。但是知道浏览器可以在几秒钟内重新安装的事实，这个选项似乎更容易。卸载浏览器后，请删除“ Temp ”、“% Temp %”和“Prefetch”文件。重新启动系统并检查它是否解决了问题。如果是这样，请等待 10-15 分钟以确认它不会再次发生。然后重新安装浏览器。

2]运行Chkdsk

运行 ChkDsk^{(Run ChkDsk)}看看是否有帮助。打开提升的CMD窗口，键入以下命令并按Enter：

chkdsk.exe /f /r

ChkDsk参数^{(ChkDsk parameters)}执行以下工作：

• /f 修复检测到的错误。
• /r  识别坏扇区^{(Identifies Bad Sectors)}并尝试恢复信息。

3]在Windows Defender中^{(Windows Defender)}禁用^(Disable)基于云的保护

打开Windows Defender并禁用基于云的保护并查看。

4]禁用Windows搜索索引器

Windows 搜索索引器^{(Windows Search Indexer)}是一个已知会导致此问题的进程。如果您不使用Windows Search，您可以禁用Windows Seach Indexer。

5]禁用打印后台处理程序服务

如果这不能解决问题，请运行services.msc并禁用“ Print Spooler ”。在此之后，您的打印机将停止工作。但至少它有助于隔离问题。禁用Print Spooler服务对许多用户都有效。

打开服务^(Services) 管理器^(Manager)后，向下滚动到“打印后台处理程序”，然后单击停止服务的选项。如果它有效，您可以决定您的工作是否真的需要打印机。如果您需要该服务，则需要技术人员级别的维修。

6]调整视觉效果

在Windows^(Windows)中调整视觉效果。这篇文章将向您展示如何调整视觉效果以优化 Windows 性能。

7]更新设备驱动程序

有时设备^(Device)驱动程序可能是罪魁祸首。所以更新你的驱动程序，看看是否有帮助。您可以使用Windows 更新^{(Windows Update)}、从制造商的网站下载或使用免费的驱动程序更新软件^{(free Driver Update software)}。

8]运行证监会和DISM

运行系统文件检查器以及DISM 来修复系统映像^{(DISM to repair the system image)}。

9]运行^(Run)性能^{(Performance Troubleshooter)}疑难解答

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。这里有更多可以帮助您解决性能问题^{(troubleshoot Performance issues)}的建议。

10]升级^(Upgrade)你的固件或升级你的RAM

您可能需要检查是否需要升级固件或升级 RAM。

11]使用刷新Windows工具

您的另一个选择是使用刷新 Windows 工具来重置Windows 10，看看这是否最终有帮助。

12]检查系统健康报告

性能监视器^{(Performance Monitor)}是一个很好的内置工具，可让您实时监控和研究您运行的应用程序如何影响计算机的性能，包括实时和收集日志数据以供日后分析。它对于识别和排除进程的高资源利用率以及生成Windows的系统健康报告非常有用。

13]使用Process Tamer进行^{(Process Tamer)}故障排除^{(Troubleshoot)}

Process Tamer是一个运行在系统托盘中并持续监控其他进程的CPU使用率的小型实用程序。当它看到一个进程使你的CPU过载时，它会暂时降低该进程的优先级，直到它的CPU使用率恢复到合理的水平。

14]是否启用了消息^{(Is Message)}信号中断？^(Interrupt)

在特殊情况下，如果您的任务管理器在启用了^{(Task Manager)}消息^(Message)信号中断^(Interrupt)( MSI ) 模式的^(MSI)Windows 10设备上显示 100% 的磁盘利用率，那么要解决此问题，请安装英特尔的芯片组^(Chipset)和管理引擎接口^{(Management Engine Interface)}驱动程序并查看。

如果您看到Random Disk Usage Spikes ，这篇文章将对您有所帮助。

15]关闭^(Turn)设备上的Windows写入缓存缓冲区刷新

Pijal在下面的评论中推荐。

转到Device Manager > Disk驱动器。右键单击您的HDD/SSD以显示Properties > Policies。选择^(Select)“关闭设备上的 Windows 写入缓存缓冲区刷新^{(Turn off Windows write-cache buffer flushing on the device)}”，然后单击“确定”。看看^{(OK. See)}这是否对你们中的一些人有帮助。

如果您有任何可能有助于解决此问题的想法，请在评论中发表。您的建议可能会帮助其他面临此问题的人。^{(If you have any ideas that may help resolve this issue, please post them in the comments. Your suggestions may help others facing this problem.)}

How to fix 100% Disk, High CPU, High Memory usage in Windows 11/10

One of thе tougheѕt issues to resolve with Windows 11/10/8/7 is when you see a 100% Disk Usage message and your PC suddenly stops responding or rеsponds slowly. While it cоuld have many reaѕons, it’s usually caused when the Disk Usage is at 100% in the Task Manager. This post also helps you face constant high CPU or high Memory usage issues.

Disk, CPU, Memory usage spikes

100% Disk, High CPU, High Memory usage in Task Manager

In this guide, we have covered a step-by-step procedure to troubleshoot the mentioned issue after studying and implementing methods discussed by others as well as our own experimentation. Many forums mention methods like disabling the Superfetch, Prefetch and the BITS services as well, but we would not recommend the same. I mean what and how much can you really disable to fix an issue!

If you are facing such an issue, here are a few troubleshooting steps that may help you resolve the issue. Create a system restore point first and then go through the entire list and decide which one or more of the suggestions you want to try.

1. Uninstall 3rd-party browsers
2. Run Chkdsk
3. Disable Cloud-based protection in Windows Defender
4. Disable Windows Search Indexer
5. Disable Print Spooler Service
6. Adjust the Visual Effects
7. Update Device Drivers
8. Run SFC & DISM
9. Run the Performance Troubleshooter
10. Upgrade your firmware or upgrade your RAM
11. Use Refresh Windows Tool
12. Examine System Health Report
13. Troubleshoot using Process Tamer
14. Is Message Signaled Interrupt enabled?
15. Turn off Windows write-cache buffer flushing on the device

Since the reasons can be many, the solutions can be many – so go through the entire list first and see which may apply in your case.

1] Uninstall 3rd-party browsers

Using the Control Panel, uninstall all browsers – except Edge and Internet Explorer of course. This is to isolate the issue with the plugins. The other suggestion is to remove the plugins one by one from each browser and test. Adobe Flash and Shockwave Player are the usual culprits. But knowing the fact that the browsers could be re-installed in seconds, this option seems to be easier. After uninstalling the browsers, please delete the ‘Temp’, ‘%Temp%’ and ‘Prefetch’ files. Restart the system and check if it solves the issue. If it does, wait for 10-15 minutes to verify that it doesn’t reoccur. Then re-install the browsers.

2] Run Chkdsk

Run ChkDsk and see if that helps. Open an elevated CMD window, type the following command and hit Enter:

chkdsk.exe /f /r

The ChkDsk parameters do the following work:

• /f  Fixes errors detected.
• /r  Identifies Bad Sectors and attempts recovery of information.

3] Disable Cloud-based protection in Windows Defender

Open Windows Defender and disable Cloud-based protection and see.

4] Disable Windows Search Indexer

The Windows Search Indexer is one process that is known to cause this. If you do not use Windows Search, you can disable Windows Seach Indexer.

5] Disable Print Spooler Service

If this doesn’t fix the issue, Run services.msc and disable the ‘Print Spooler’. Your printer will stop working after this. But at least it helps isolate the issue. Disabling the Print Spooler service has worked for many users.

Once the Services Manager is opened, scroll down to ‘Print Spooler’ and click on the option to stop the service. If it works, you could decide if your work actually needs a printer. If you need the service, a technician level repair would be needed.

6] Adjust the Visual Effects

Adjust the Visual Effects in Windows. This post will show you how to tweak Visual Effects to optimize Windows performance.

7] Update Device Drivers

Sometimes Device Drivers can be the culprit. So update your Drivers and see if that helps. You could use Windows Update, download it from the manufacturer’s website or use a free Driver Update software.

8] Run SFC & DISM

Run System File Checker as well as DISM to repair the system image.

9] Run the Performance Troubleshooter

Open an elevated Command Prompt, type the following and hit Enter to run the Performance Troubleshooter.

msdt.exe /id PerformanceDiagnostic

This troubleshooter helps the user adjust settings to improve operating system speed and performance. Here are more suggestions that can help you troubleshoot Performance issues.

10] Upgrade your firmware or upgrade your RAM

You may want to check if you need to upgrade your firmware or upgrade your RAM.

11] Use Refresh Windows Tool

Another option you have would be to use the Refresh Windows Tool to reset Windows 10 and see if that finally helps.

12] Examine System Health Report

The Performance Monitor is a good built-in tool that lets you monitor and study how applications you run affect your computer’s performance, both in real-time and by collecting log data for later analysis. It is quite useful in identifying and troubleshooting high resource utilization by processes and in generating a System Health Report of your Windows.

13] Troubleshoot using Process Tamer

Process Tamer is a tiny utility that runs in your system tray and constantly monitors the CPU usage of other processes. When it sees a process overloading your CPU, it reduces the priority of that process temporarily, until its CPU usage returns to a reasonable level.

14] Is Message Signaled Interrupt enabled?

In a special scenario, if your Task Manager shows 100% disk utilization on Windows 10 devices with Message Signaled Interrupt (MSI) mode enabled, then to solve this install Intel’s Chipset and Management Engine Interface driver and see.

This post will help you if you see Random Disk Usage Spikes.

15] Turn off Windows write-cache buffer flushing on the device

Pijal recommends in the comments below.

Go to Device Manager > Disk drives. Right-click on your HDD/SSD to shown Properties > Policies. Select “Turn off Windows write-cache buffer flushing on the device” and click OK. See if this helps some of you.
