几乎在任何Windows笔记本电脑或台式机上，CPU的运行速度都会有所不同。您应该知道CPU不会一直全速运行。这取决于操作系统如何分配负载，并相应地工作。但是，如果CPU在^(CPU)Windows 11/10中即使在繁重的工作负载下也没有全速运行，那么这种情况需要引起注意。如果要验证，可以运行任何CPU 压力测试工具^{(CPU stress test tool)}来检查速度是否保持低速。

CPU未以全速或容量运行

这种情况在笔记本电脑中更常见，因为它们使用电池运行。英特尔处理器^{(Intel Processor)}使用速度步进技术^{(Speed Stepping Technology)}。这意味着当您在执行小任务时，处理器的速度会降低。

但是，如果在使用繁重的应用程序时发生这种情况，可能是因为电池电量不足。Windows将尽最大努力使计算机尽可能长时间地运行。它通过降低处理器或CPU速度来实现。但是，有时，您准备牺牲电池以确保工作按时完成。

1]在电源^(Power)选项中将处理器状态设置为最大值^(Set)

在搜索框中键入控制。^(control)它将显示经典的控制面板^{(Control Panel)}以及流行的选项。

单击^(Click)电源Power Options > Change计划设置 >更改^(Change)高级电源设置。

使用电池^(Battery)并插入^(Plugged)时选择 100% 。

接下来，展开系统冷却策略选项，^{(System cooling policy option,)}并确保将其设置为Active。这将确保不会过热。

将此更改应用于电源管理的所有配置文件。

这样，您的CPU将始终以最大功率运行。

2]更新^(Update)或禁用英特尔电源管理驱动程序^{(Intel Power Management Driver)}

英特尔驱动的计算机有专门的软件来控制CPU速度和风扇^(Fan)速度，当它需要节省电池时。您可以尝试暂时禁用它，并检查CPU风扇速度是否发生变化。

按住SHIFT^(SHIFT)键重新启动计算机，将计算机引导至故障排除或高级模式。

转到疑难解答^{(Troubleshoot)}>高级选项^{(Advanced Options)}>命令提示符^{(Command Prompt)}。

将目录更改^(Change)为 C:WindowsSystem32driver。

^{(Rename Intelppm)}使用以下命令重命名 Intelppm文件：

ren intelppm.sys intelppm.sys.bak

重新启动计算机。

C:\Windows\System32\driver中找不到驱动程序 ，请检查它们是否在C:\Drivers\IntelPPM下可用。

CPU速度现在应该随着系统中缺少Intel驱动程序而改变。如果要启用它，请按照相同的步骤，然后再次重命名文件。

3]通过注册表^(Registry)或命令行^{(Command Line)}禁用IPPM^{(Disable IPPM)}

在开始^(Start)搜索框中键入regedit ，然后^(regedit)按 Enter^(Enter)。

导航：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\intelppm

双击^{(Double-click)}，然后将Start键的值更改为4。

关闭注册表编辑器^{(Registry Editor)}并重新启动计算机。

或者，您可以在提升的命令提示符下执行以下命令：

sc config intelppm start= disabled

Sc config命令修改注册表和服务控制管理器^{(Service Control Manager)}数据库中服务条目的值。

这些提示应确保CPU始终以最大功率运行。

为什么我的 CPU 运行速度比应有的慢？

原因可能有很多——可能^{(– May)}您正在使用高CPU消耗程序，您的 PC 感染了恶意软件，您的电源^(Power)计划可能无法帮助CPU，等等。

如何修复低CPU使用率并让我的CPU全速运行？

您可以执行的一些基本步骤是 -重新启动^(Restart)计算机并查看、更新您的Windows PC、全面^(Full)扫描您的系统以查找恶意软件、减少启动项、禁用省电模式^{(Battery Saver Mode)}，以及在高性能电源模式下^{(High-Performance Power Mode)}运行Windows。如果他们没有帮助，上述建议之一肯定会对您有所帮助。

虽然可以在台式机上执行此操作，但请确保在使用笔记本电脑时明智地使用它。^{(While it is fine to do it on desktops, make sure to use it wisely when using laptops.)}

CPU is not running at full speed or capacity in Windows 11/10

Almost on any Windows laрtop or desktoр, the speed at which the CPU runs varies. You should know that the CPU doesn’t run at full speed all the time. It depends on how the OS distributes the load, and it works accordingly. However, if the CPU is not running at full speed in Windows 11/10 even on a heavy workload, then the situation needs some attention. If you want to verify, you can run any CPU stress test tool to check if the speed stays low.

CPU is not running at full speed or capacity

This scenario occurs more often in laptops as they run on battery. Intel Processor uses Speed Stepping Technology. It means when you are, doing small tasks the speed of the processor is reduced.

However, if this happens when using a heavy application, it can be because of a low charge on the battery. Windows will try its best to keep the computer running as long as possible. It does it by reducing the processor or CPU speed. However, at times, you are ready to sacrifice battery to make sure the work completes on time.

1] Set the processor state to the maximum in Power Options

Type control in the search box. It will reveal the classic Control Panel along with popular options.

Click on Power Options > Change plan settings > Change advanced power settings.

Select 100% when its on Battery and Plugged in.

Next, expand the System cooling policy option, and make sure to set it as Active. This will make sure there will no overheating.

Apply this change to all the profiles of power management.

This way, your CPU will run at maximum power all the time.

2] Update or disable the Intel Power Management Driver

Intel-powered computers have dedicated software which controls CPU speed, and Fan speed when it needs to save battery. You can try to disable it, temporarily, and check if the CPU fan speed changes.

Restart the computer by holding the SHIFT key to boot the computer into Troubleshooting or advanced mode.

Go to Troubleshoot > Advanced Options > Command Prompt.

Change directory to C:\Windows\System32\driver.

Rename Intelppm file by using this command:

ren intelppm.sys intelppm.sys.bak

Reboot the computer.

In case you cannot find the drivers in C:\Windows\System32\driver, check if they are available under C:\Drivers\IntelPPM.

The CPU speed should change now with the Intel driver missing from the system. If you want to enable it, follow the same steps, and rename the file again.

3] Disable IPPM via Registry or Command Line

Type regedit in the Start search box and hit Enter.

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\intelppm

Double-click on, and then change the value of Start key to 4.

Close the Registry Editor and restart your computer.

Alternatively, you may execute the following in an elevated command prompt:

sc config intelppm start= disabled

Sc config command modifies the value of a service’s entries in the registry and the Service Control Manager database.

These tips should make sure that the CPU runs at maximum power at all the time.

Why is my CPU running slower than it should?

The causes can be many – May you are using a high-CPU consuming program, your PC is infected with malware, your Power Plan may not be helping the CPU, and so on.

How do I fix low CPU usage and make my CPU run at full speed?

Some basic steps you can carry out are – Restart your computer and see, Update your Windows PC, Full scan your system for malware, reduce startup items, disable Battery Saver Mode, and run Windows in High-Performance Power Mode. If they do not help, the one of the above suggestions will surely help you.

While it is fine to do it on desktops, make sure to use it wisely when using laptops.
