通过系统空闲进程修复高 CPU 使用率： ^{(Fix High CPU Usage by System Idle Process: )}如果您无法正确使用计算机，那么很可能某些进程正在占用您的所有系统资源，从而导致冻结或滞后等问题。特别是，一个名为System Idle的进程进程^{(System Idle Process)}是罪魁祸首，它占用了 99% 的CPU。在某些情况下，除了CPU之外，此过程还使用高内存或磁盘使用率。

为什么系统空闲进程占用这么多CPU？^{(Why is the System Idle Process taking up so much CPU?)}

一般来说，使用 99% 或 100% CPU的 System ^(CPU)Idle^{(System Idle)}进程不是问题，因为System Idle Process意味着计算机什么都不做，如果它在 99% 时处于空闲状态，那么这意味着系统 99% 处于静止状态。系统空闲进程情况下的CPU使用率通常是衡量其他进程未使用多少CPU的指标。^(CPU)但是，如果您遇到延迟或者您觉得您的计算机速度很慢，那么这是一个需要解决的问题。

系统空闲进程导致计算机缓慢的可能原因有哪些：^{(What are the possible reasons for the System Idle Process causing Computer slowness:)}

• 病毒或恶意软件感染
• 硬盘已满，未优化，即没有碎片整理
• 系统上安装了不需要的程序或工具栏
• 后台运行了太多不必要的启动程序
• 安装了多个防病毒软件
• 损坏或有故障的设备驱动程序

我可以杀死系统空闲进程吗？^{(Can I Kill System Idle Process?)}

由于System Idle Process是一个System进程，您不能简单地^{(you cannot simply kill it)}从Task Manager中杀死它。真正的问题是你为什么要这样做？

系统空闲进程^{(System Idle Process)}只是一个空闲进程，当计算机完全无事可做时，由操作系统运行。现在如果没有这个过程，系统可能会冻结，因为在空闲时没有任何东西占用您的处理器，处理器将简单地停止。

因此，如果上述任何事情对您的 PC 来说都是正确的，那么您可能会面临系统空闲进程问题导致的高^{(System Idle Process)}CPU使用率，这反过来又会使您的 PC 变慢。无论如何^(Anyway)，不​​要浪费任何时间，让我们在下面列出的故障排除指南的帮助下看看如何通过系统空闲进程修复高 CPU 使用率。^{(How to Fix High CPU Usage by System Idle Process)}

How to Fix High CPU Usage by System Idle Process

Fix High CPU Usage by System Idle Process: If you’re not able to use your computer properly then chances are some processes are taking up all your system resources causing issues such as freezing or lagging etc. In this particular, a process called System Idle Process is the culprit, which is utilizing 99% of your CPU. In some cases, this process also utilizes high memory or disk usage in addition to the CPU.

Why is the System Idle Process taking up so much CPU?

Generally, System Idle process utilizing 99% or 100% CPU is not a problem, because the System Idle Process means that the computer is doing nothing and if it is idle at 99% then this means that the system is 99% at rest. The CPU usage in the case of the system idle process is generally a measure of how much CPU is not being used by other processes. But if you are facing a lag or you feel your computer is slow then this is a problem which needs to be fixed.

What are the possible reasons for the System Idle Process causing Computer slowness:

• Virus or Malware infection
• The hard drive is full, not optimized i.e. no defragmentation
• Unwanted programs or toolbars installed on the system
• Too many unnecessary startup programs running in the background
• More than one Anti-virus installed
• Corrupt or faulty device driver

Can I Kill System Idle Process?

As System Idle Process is a System process, you cannot simply kill it from Task Manager. The real question is why would you want to?

The System Idle Process is just an idling process which is run by the operating system when the computer has absolutely nothing better to do. Now without this process, the system could potentially freeze since, without anything occupying your processor when it’s idle, the processor will simply stop.

So if anything above is true for your PC then chances are you might be facing the high CPU usage by System Idle Process issue which in turn making your PC slow. Anyway, without wasting any time let’s see How to Fix High CPU Usage by System Idle Process with the help of the below-listed troubleshooting guide.

Method 5: Run Disk Defragmentation

Now Disk defragmentation re-arranges all the pieces of data that are spread across your hard drive and stored them together again. When the files are written to disk, it is broken into several pieces as there is not enough contiguous space to store the complete file, hence the files become fragmented.

Defragmentation reduces file fragmentation thus improving the speed by which data is read and written to disk which ultimately increases the performance of your PC. Disk defragmentation also cleans the disk thus increasing the overall storage capacity. So without wasting any time let’s see How to Optimize and Defragment Drives in Windows 10.

Method 6: Run CCleaner and Malwarebytes

Malware can cause tremendous trouble in various services and programs including the High CPU Usage. The possibilities of creating issues by malware are endless. So, it is recommended to download and install applications like Malwarebytes or other anti-malware applications to scan for malware in your system. This may fix the High CPU Usage by System Idle Process issue.
