当您启动Windows计算机时，即使在操作系统启动之前，幕后也会发生很多事情。存储在主板上的(programs stored on the motherboard)一些程序可以让计算机中的所有内容都准备好启动操作系统。操作系统上的其他程序可确保在您关闭计算机之前对计算机所做的更改和设置在重新启动时保持不变。
一个这样的程序是英特尔图形可执行主模块(Intel Graphics Executable Main Module)，简称为IgfxEM模块。它是Windows(Windows)操作系统不可分割的一部分，通常在后台运行，不会影响 PC 的性能。
但是，在某些情况下，此图形模块会构成麻烦。我们已经看到有关IgfxEM 进程使用高 CPU 资源(IgfxEM process using high CPU resources)、升高CPU 温度(CPU temperature)和其他异常的投诉和报告。
在这个解释器中，我们将引导您了解IgfxEM 模块(IgfxEM Module)是什么、它的作用以及如何确定它对您的 PC 是否安全。我们还将向您展示如何解决与IgfxEM.exe进程相关的问题。
什么是 IgfxEM.exe
igfxEM.exe 是英特尔图形可执行主模块(Intel Graphic Executable Main Module)的可执行文件和组件。如果您的 PC 使用Intel显卡，您会发现 igfxEM.exe 进程在后台运行。一些NVIDIA和AMD显卡驱动程序也使用此可执行文件。
例如，当您更改 PC 的屏幕分辨率(change your PC’s screen resolution)时，igfxEM.exe 充当您的显卡和 PC 显示界面之间的中间人。它将您的操作传达给图形卡，更改屏幕分辨率，并确保新分辨率保持不变——即使您关闭 PC 也是如此。
igfxEM 进程还与您的 PC 显卡协同工作，以修改键盘快捷键(keyboard shortcuts)和其他与显示相关的配置，如屏幕旋转。
高CPU使用率：igfxEM模块安全(Module Safe)吗？
尽管 igfxEM.exe 文件对于保持 PC 的某些功能平稳运行很重要，但它不是核心 Windows 10 系统文件。它由Intel Corporation设计和开发，但也由(Intel Corporation)Microsoft进行数字验证/签名。这证明 igfxEM.exe 是正版文件。
但是，文件的真实性并不能完全保证其安全。如果由于某种原因，igfxEM.exe 进程继续消耗CPU资源，那么它对您的计算机的健康来说变得不安全。还有恶意软件模拟的问题。
igfxEM.exe 的安全性与两件事有关：文件的数字认证及其在您计算机上的行为。综上所述，igfxEM.exe CPU使用率高的原因如下：
- 当 igfxEM 模块与其他软件或后台进程发生冲突时。
- 当恶意软件或病毒伪装/模仿 igfxEM.exe 文件对您的 PC 造成伤害时。
在下一节中，我们将向您展示如何检查您的计算机上是否安装了正版 igfxEM.exe 文件。
您的 IgfxEM.exe 文件是正版吗？
igfxEM.exe 文件与英特尔(Intel)图形套件捆绑在一起。这意味着它会自动安装在您 PC 的图形驱动程序旁边。但是，如果进程出现故障，您应该检查文件是否真实，或者恶意软件是否隐藏在 igfxEM 可执行文件的幌子下。
- 在Windows 搜索(Windows Search)框中键入igfxem ，在搜索结果中右键单击igfxem（或IgfxEM.exe），然后选择打开文件位置(Open file location)。
- 右键单击igfxem.exe并从上下文菜单中选择属性。(Properties)
- 转到数字签名(Digital Signatures)选项卡并检查签名(Signature)列表表。
如果英特尔(Intel)（或英特尔公司(Intel Corporation)）和微软(Microsoft)是数字签名者，您无需担心。否则，您 PC 上的 igfxem.exe 文件不是正版且很可能是恶意软件。你应该尽快(ASAP)删除它。
igfxEM.exe 错误疑难解答
有几个因素会触发 igfxEM.exe 文件引发错误消息、消耗大量虚拟内存或使用高CPU资源。幸运的是，还有一些方法可以遏制其过度行为。

如果是恶意软件，请使用病毒或恶意软件扫描程序(virus or malware scanner)将其从您的 PC 中删除。否则，请遵循推荐的故障排除解决方案以减少其CPU使用率。
What is IgfxEM Module in Windows 10 (and Is It Safe?)
When уou power on your Windows computer, there’s a lot that goes on behind the scenes, even before the operating sуstem boots. Some programs stored on the motherboard get everything in the computer ready to start the OS. Other programs on the OS ensure that changes and settings made to your computer before you shut it down remain the same upon restart.
One such program is the Intel Graphics Executable Main Module, shortly called the IgfxEM module. It’s an integral part of the Windows operating system and usually, it runs in the background without affecting your PC’s performance.
However, there are instances when this graphics module constitutes a nuisance. We’ve seen complaints and reports of the IgfxEM process using high CPU resources, raising CPU temperature, and other abnormalities.
In this explainer, we’ll walk you through what the IgfxEM Module is, what it does, and how to determine if it is safe for your PC or not. We’ll also show you how to fix problems relating to the IgfxEM.exe process.
What Is IgfxEM.exe
igfxEM.exe is the executable file and component of the Intel Graphic Executable Main Module. You’ll find the igfxEM.exe process running in the background if your PC uses an Intel graphics card. Some NVIDIA and AMD graphics card drivers also use this executable file.
When you change your PC’s screen resolution, for example, igfxEM.exe acts as a middleman between your graphics card and your PC’s display interface. It communicates your action to the graphics card, changes the screen resolution, and makes sure the new resolution stays the same—even when you power off your PC.
The igfxEM process also works collaboratively with your PC’s graphics cards to modify keyboard shortcuts and other display-related configurations like screen rotation.
High CPU Usage: Is the igfxEM Module Safe?
Although the igfxEM.exe file is important to keep some features of your PC running smoothly, it’s not a core Windows 10 system file. It’s designed and developed by Intel Corporation but also digitally verified/signed by Microsoft. This certifies the igfxEM.exe as a genuine file.
However, the genuineness of the file doesn’t totally guarantee its safety. If for some reason, the igfxEM.exe process continues to consume CPU resources, then it becomes unsafe for the health of your computer. There’s also the issue of malware impersonation.
The safety of igfxEM.exe is relative to two things: the file’s digital certification and its behavior on your computer. In summary, the following factors are responsible for igfxEM.exe high CPU usage:
- When the igfxEM module conflicts with other software or background processes.
- When malware or virus camouflages/imitates the igfxEM.exe file to cause harm to your PC.
In the next section, we’ll show you how to check if you have the genuine igfxEM.exe file installed on your computer.
Is Your IgfxEM.exe File Genuine?
The igfxEM.exe file comes bundled with the Intel graphics suite. This means that it’s automatically installed alongside your PC’s graphics driver. However, if the process is malfunctioning, you should check if the file is genuine or if malware is hiding under the guise of the igfxEM executable file.
- Type igfxem in the Windows Search box, right-click igfxem (or IgfxEM.exe) in the search result, and select Open file location.
- Right-click on igfxem.exe and select Properties from the context menu.
- Go to the Digital Signatures tab and check the Signature list table.
If Intel (or Intel Corporation) and Microsoft are the digital signatories, you have nothing to worry about. Otherwise, the igfxem.exe file on your PC is not genuine and most likely malware. You should delete it ASAP.
Troubleshooting igfxEM.exe Errors
There are several factors that trigger the igfxEM.exe file to throw error messages, consume large virtual memory, or use high CPU resources. Luckily, there are also a handful of ways to curb its excesses.
1. Force Stop the igfxEM Module
This is by far the quickest (and easiest) way to put a rogue igfxEM module in order. Launch the Windows Task Manager (press Ctrl + Shift + Esc), right-click the igfxEM module, and select End task.
You can also reduce the CPU usage of the IgfxEM module by closing other unnecessary applications that are active in the background. Try the next solution if the process initiates itself (i.e. if it comes back on automatically) and continues to overburden your PC’s CPU or memory.
2. Update Your Graphics Card Driver
The igfxEM.exe process may malfunction if your computer’s graphics card driver is out of date. You can check if an update for the Intel graphics card is available using the Windows Device Manager.
Right-click the Start button and select Device Manager. Expand the Display adapters section and right-click on your graphics card’s adapter and select Update Driver or Update Driver Software.
Select Search automatically for update driver software. The Device Manager will search your computer and the internet for the latest graphic card driver software available for your device. So make sure you’re connected to the internet before you proceed.
If the Device Manager doesn’t find an update for the driver, you can use Intel’s Driver & Support Assistant (Intel DSA). The tool is a little more reliable for updating Intel graphic drivers. Head to Intel’s support page, download the Driver & Support Assistant setup file, and install it on your computer.
Connect your PC to the internet and launch the app. That’ll redirect you to a resource page where you’ll find driver and software updates available for your computer.
3. Disable the IgfxEM Process
If your graphics driver is up-to-date but the problem continues, try disabling IgfxEM.exe using the System Configuration tool.
1. Launch the Windows Run box (Windows key + R). Type msconfig into the dialog box and click OK.
2. Navigate to the Services tab.
3. Scroll through the list of services and uncheck the igfxEM Module.
4. Click Apply and then OK to proceed.
4. Scan for Malware and Viruses
Viruses and malware can cause an unreasonable spike in CPU usage for certain processes. Run a virus scan using the Windows Defender or trusted third-party antivirus software. Refer to our tutorial on how to thoroughly scan a Windows 10 PC for viruses and malware.
TL;DR: The IgfxEM Module Can Be Both Safe and Unsafe
The IgfxEM allows your PC’s graphics card to function to its fullest potential. When it works correctly, you have nothing to worry about. However, if you notice that the module consumes too much CPU space, make sure you check that it’s digitally signed and verified—not malware in disguise.
If it’s malware, use a virus or malware scanner to remove it from your PC. Otherwise, follow the recommended troubleshooting solutions to reduce its CPU usage.
