服务主机诊断策略服务^{(Service Host Diagnostic Policy Service)}是默认安装在所有Windows 11/100系统中的一项重要服务策略。该服务的功能是检测和解决Windows 11/10系统组件的问题。它会自动启动纠正措施并通知用户潜在问题。它还为问题原因创建适当的诊断信息日志。

诊断策略服务^{(Diagnostic Policy Service)}在共享服务主机^{(Service Host)}进程 ( svchost.exe )下的所有Windows 11/10如果此过程不运行，您将无法知道系统错误的原因。您可以在任务管理器^{(Task Manager)}中找到该进程正在运行，您可以通过右键单击任务栏^(Taskbar)来启动该进程。现在，在“进程^(Processes)”选项卡中向下滚动以查看在后台运行的进程。

诊断策略服务^{(Policy Service)}( DPS ) 显示 100% 磁盘使用率

由于Windows 10 PC 上的诊断策略服务^{(Policy Service)}，许多人遇到高磁盘使用率。^{(high disk usage)}如果服务异常消耗磁盘空间，会影响整个系统的性能，用户会遇到系统卡顿的问题。在某些情况下，以安全模式重新启动系统^{(rebooting the system in safe mode)}可能会有所帮助。以安全模式重新启动计算机可以解决大多数问题。如果这不起作用，请尝试下面列出的方法。

删除 SRUDB.dat 文件

诊断策略服务^{(Diagnostic Policy Service)}不断在SRUDB.dat文件^(SRUDB.dat)中创建日志。这使得它的尺寸很大。这是DPS^(DPS)服务消耗大量磁盘空间的原因之一。因此^(Hence)，删除此文件可能会解决问题。按照下面列出的步骤删除SRUDB.dat文件。

1]首先^(First)，您必须停止DPS服务。如本文前面所述，在任务管理器^{(in the Task Manager)}中找到该服务。选择它并单击任务管理器^{(Task Manager)}底部的“结束任务^{(End task)}”按钮。

2]屏幕上将出现一个弹出窗口。选中“放弃未保存的数据并关闭^{(Abandon unsaved data and shut down)}”框，然后单击“关闭^{(Shut down)}”。

3] 现在，按键盘上的“ Ctrl + R ”并输入“ services.msc ”，然后单击“确定”。它将打开服务管理器^{(open the Services Manager)}。

4]在“服务^(Services)”窗口中，向下滚动以搜索“诊断策略服务^{(Diagnostic Policy Service)}”。右键单击它并选择“属性^(Properties)”。

5]在“常规^(General)”选项卡中，单击“停止^(Stop)”，然后单击“确定”。

6] 现在，再次启动“运行”^(Run)窗口并键入“ %WinDir%\System32\sru ”，然后单击“确定”。 

7] 在资源管理器窗口中，删除SRUDB.dat文件。 

重新启动系统。

您应该注意的一些要点

为了获得最佳的计算机性能^{(optimum computer performance)}和正常的磁盘使用^{(normal disk usage)}，必须遵循一些要点。我们在这里列出了这些要点。

• 运行磁盘清理^{(Run disk cleanup)}
• 最好在系统硬盘上至少有 30% 或 30 GB 的可用空间以获得最佳效果。
• 拔下当前未使用的外部设备。
• 减少启动程序^{(Reduce startup programs)}——确保后台没有运行无用的进程。
• 使您的 BIOS 保持最新^{(Keep your BIOS up to date)}。您可以从计算机制造商的网站下载它。

Service Host: Diagnostic Policy Service 100% Disk Usage on Windows PC

Service Host Diagnostic Policy Service is a crucial service policy that is installed by default in all Windows 11/100 systems. The function of this service is to detect and troubleshoot the issues on Windows 11/10 system components. It initiates the corrective action automatically and notifies the user about the potential issue. It also creates a log for appropriate diagnostic information for the cause of the issues.

The Diagnostic Policy Service runs automatically in all Windows 11/10 PCs under the shared Service Host process (svchost.exe). If this process does not run, you will not be able to know the cause of your system errors. You can find this process running in the Task Manager, which you can launch by right-clicking on the Taskbar. Now, scroll down in the “Processes” tab to view the process running in the background.

Restart your system.

Some important points that you should take care of

There are some points that are necessary to follow for optimum computer performance and normal disk usage. We are listing these points here.

• Run disk cleanup
• Preferably, you should have at least 30% or 30 GB of free space on your system’s hard drive to get optimum results.
• Unplug the external devices that are not currently in use.
• Reduce startup programs – Make sure that there is no useless process running in the background.
• Keep your BIOS up to date. You can download it from your computer manufacturer’s website.

Hope this article will help you solve the issue of 100% disk usage by Diagnostic Policy Service.
