您在计算机屏幕上看到的所有内容，无论是Windows、Mac还是Linux设备，都是由控制从网络连接到用户界面的所有内容的系统进程生成的。Windows用户可能熟悉其中的一些，包括用于显示桌面的 explorer.exe，但其他用户可能不太熟悉。
dwm.exe 等系统进程是Windows(Windows)操作系统的常见组成部分。特别是Dwm.exe(Dwm.exe)有助于为Windows创建图形用户界面，但有时会导致CPU使用率过高。如果是这种情况，您需要执行以下操作来解决问题。
什么是 Dwm.exe？(What Is Dwm.exe?)
dwm.exe（桌面窗口管理器(Desktop Window Manager)）进程是一个重要的系统进程，负责您的图形用户界面。特别是，它有助于生成您在使用Windows(Windows)时会看到的视觉效果，例如透明窗口和任务栏缩略图。
这是由于Windows用于创建此类效果的方法。当您打开新软件时，用户界面的设计会记录到Windows内存中，从而可以生成设计。然后， Windows(Windows)采用这些窗口设计并对其进行操作，以确保应用它自己的视觉效果。
Windows使用硬件加速来帮助为用户提供无缝体验，在此过程中使用您的图形硬件(graphics hardware)，但如果您的图形卡（或内置图形芯片组）不能这样做，它可以默认为软件渲染.
是什么导致 Dwm.exe 高 CPU 使用率以及它可能是恶意软件？(What Causes Dwm.exe High CPU Usage & Can it Be Malware?)
Windows将利用您 PC 的全部功能来创建视觉效果，无论您是使用标准Windows主题还是将新的视觉主题(new visual themes)应用到您的 PC。
但是，如果 dwm.exe 进程在Windows 任务管理器(Windows Task Manager)中占用大量CPU使用率，则表明您的硬件或系统配置存在问题。
与其依靠您的显卡来帮助创建视觉效果，不如使用您的CPU来创建它们。如果您的 PC 稍旧，这可能会影响系统的运行方式。更高的CPU使用率可能意味着更高的温度和更不稳定的系统。
虽然恶意软件不是dwm.exe 进程导致CPU使用率高的典型原因，但不能排除这种情况。据报道，一些恶意软件会尝试复制DWM进程，因此隐藏在众目睽睽之下。
dwm.exe 导致CPU(CPU)使用率高的其他原因可能是驱动程序过时或缺少Windows系统更新，以及您的内部显卡（而不是外部显卡）被用于生成视觉效果。
如何禁用或删除桌面窗口管理器 (dwm.exe) 进程(How to Disable or Remove the Desktop Window Manager (dwm.exe) Process)
虽然旧版本的Windows允许您关闭桌面窗口管理器(Desktop Window Manager)(dwm.exe) 进程，但在 Windows 10 中不再可能。(no longer possible)
DWM流程现在已牢固地集成到Windows用户体验中，这意味着您使用的图形用户界面依赖于它来工作。虽然可以在Windows 设置(Windows Settings)中禁用您看到的某些视觉效果，但您无法阻止 dwm.exe 进程运行。
也无法将其删除。dwm.exe 是必不可少的系统进程，因此除非您想完全破坏Windows 10（并因此被迫擦除和重置 Windows(wipe and reset Windows)），否则您应该不理会它。
Dwm.exe 高 CPU 使用率的潜在修复(Potential Fixes for Dwm.exe High CPU Usage)
桌面窗口管理器(Desktop Window Manager)进程无法关闭或禁用，但如果您发现它占用了您的系统资源，可以尝试一些潜在的修复程序，尤其是在您的CPU使用率异常高的情况下。
检查 Windows 系统更新(Check for Windows System Updates)
Windows用户的第一个（可能也是最重要的）修复是让您的系统保持更新(keep your system updated)。Microsoft会定期发布错误修复和系统升级，这有助于提高您的整体系统稳定性，尤其是对于较新的硬件。
- 您可以通过右键单击“开始(Start)”菜单并按“设置”(Settings)选项来检查Windows 设置中的更新。(Windows Settings)在Windows 设置(Windows Settings)菜单中，按Update & Security > Windows Update > Check for updates以检查并安装适用于您的 PC 的任何最新系统更新。
更新后，重新启动 PC 以查看更新是否对 dwm.exe 进程有任何影响。
检查图形驱动程序更新(Check for Graphics Driver Updates)
如果Windows是最新的，下一步是确保您的图形驱动程序也是最新的。您可能会发现您需要查看制造商的网站以获取最新的驱动程序版本，因为驱动程序通常会在很久以后到达Windows更新系统。
例如，NVIDIA卡所有者需要查看 NVIDIA 网站(check the NVIDIA website)以获取最新更新，这些更新通常与主要游戏或硬件版本一起发布。这些还附带了最新的错误修复，可以帮助解决异常问题，例如高CPU使用率。
检查您的显卡是否被使用(Check Your Graphics Card Is Being Used)
如果您安装了新显卡(installed a new graphics card)并更新了驱动程序，您还应该检查显卡是否使用正确。
如果您错误地将显示器电缆连接到主板而不是显卡，您的显卡将被忽略。这可能会导致Windows默认使用软件加速来获得视觉效果。
- 您可以在Windows 任务管理器(Windows Task Manager)中仔细检查是否是这种情况。右键单击任务栏并单击任务管理器(Task Manager)将其打开，然后按任务管理器窗口中的性能选项卡。(Performance)
具有多个GPU的设备（例如，主板内置GPU和外部显卡的 PC）将显示在此处，列为GPU 0、GPU 1等。如果内部图形芯片的资源使用情况更高，这意味着您的显卡没有被使用。
为帮助解决此问题，请检查显示器和显卡之间的连接，以确保使用了正确的设备。
扫描 Windows 中的恶意软件(Scan Windows for Malware)
如果您的系统是最新的并且工作正常，那么高CPU使用率可能表明存在恶意软件感染。
确保彻底扫描 Windows 10 中的恶意软件，包括使用(scan Windows 10 for malware)Windows 安全(Windows Security)中心或其他防病毒软件运行启动级扫描。如果您担心 dwm.exe 进程不是正式的系统进程，您可以在Windows 任务管理器(Windows Task Manager)中仔细检查。
- 为此，请右键单击任务栏并选择任务管理器( Task Manager)，然后在任务管理器窗口的(Task Manager)进程(Processes)选项卡下找到正在运行的桌面窗口管理器(Desktop Window Manager )进程。按打开文件位置选项可在(Open file location)Windows 文件资源管理器(Windows File Explorer)中打开该运行文件的位置。
这会将您带到桌面窗口管理器(Desktop Window Manager)进程的位置。如果文件位置不是C:\Windows\System32 文件夹，那么运行的进程不是官方的 dwm.exe 文件。
如果是这种情况，请运行另一个恶意软件扫描，如果没有其他方法，您可能需要考虑让 Windows 恢复出厂设置(giving Windows a factory reset)，以确保您拥有全新的配置。
Windows 10 中的其他重要系统进程(Other Important System Processes in Windows 10)
桌面窗口管理器(Desktop Window Manager)( dwm.exe) 进程只是您以前可能没有听说过的许多重要系统进程之一。与svchost.exe和其他类似，dwm.exe 有时会与CPU使用率峰值相关联。但在许多情况下，这可以通过更新您的 PC 和检查恶意软件(checking for malware)来解决。
虽然无法禁用 dwm.exe，但您可以在Windows 设置(Windows Settings)中关闭一些较新的 Windows 10 视觉效果。如果恶意软件不是原因，这可能有助于处理CPU峰值。(CPU)但是，如果您的 PC 遇到困难，您可能需要寻找替代方案，包括升级您的硬件。(upgrading your hardware)
Why Dwm.exe Causes High CPU Usage and How To Fix It
Everything yoυ see on a computer screen, whether it’s a Windows, Maс, or Linux device, is generated by system processes that control everythіng from your network conneсtion to your user interface. Windows users might be familiar with some оf these, including explorer.exe to show your desktop, but others will be lesѕ familiar.
System processes like dwm.exe are common and integral parts of the Windows operating system. Dwm.exe, in particular, helps to create a graphical user interface for Windows, but it can sometimes cause high CPU usage. If that’s the case, here’s what you’ll need to do to fix the problem.
What Is Dwm.exe?
The dwm.exe (Desktop Window Manager) process is an important system process with responsibility for your graphical user interface. In particular, it helps to generate visual effects, such as transparent windows and taskbar thumbnails, that you’ll see when you’re using Windows.
This is due to the approach Windows uses to create these kinds of effects. When you open new software, the design of the user interface is logged to Windows memory, allowing the design to be generated. Windows then takes these window designs and manipulates them to ensure that its own visual effects are applied.
Windows uses hardware acceleration to help make this a seamless experience for users, making use of your graphics hardware in the process, although it can default to software rendering if your graphics card (or built-in graphics chipset) isn’t able to do so.
What Causes Dwm.exe High CPU Usage & Can it Be Malware?
Windows will use the full power of your PC to create visual effects, whether you’re using the standard Windows theme or applying new visual themes to your PC.
If the dwm.exe process is using a large amount of your CPU usage in Windows Task Manager, however, that would indicate a problem with your hardware or system configuration.
Rather than relying on your graphics card to help create the visual effects, your CPU will be used to create them instead. If your PC is a little older, this can have an impact on how your system is performing. Higher CPU usage can mean higher temperatures and a more unstable system as a result.
While malware isn’t a typical cause of high CPU usage with the dwm.exe process, it can’t be ruled out. Some malware has been reported to try and replicate the DWM process, therefore hiding in plain sight.
Other causes for dwm.exe causing high CPU usage could be outdated drivers or missing Windows system updates, as well as your internal graphics (rather than external graphics card) being used to generate visual effects.
How to Disable or Remove the Desktop Window Manager (dwm.exe) Process
While older versions of Windows allowed you to switch the Desktop Window Manager (dwm.exe) process off, this is no longer possible in Windows 10.
The DWM process is now firmly integrated into the Windows user experience, meaning the graphical user interface you use relies on it to work. While some of the visual effects you see can be disabled in Windows Settings, you can’t stop the dwm.exe process from running.
It’s also not possible to remove it. The dwm.exe is an essential system process, so unless you want to break Windows 10 completely (and be forced to wipe and reset Windows as a result), you should leave it alone.
Potential Fixes for Dwm.exe High CPU Usage
The Desktop Window Manager process can’t be switched off or disabled, but there are some potential fixes you can try if you find it eating up your system resources, especially if your CPU usage is unusually high.
Check for Windows System Updates
The first (and probably most important) fix for Windows users is to keep your system updated. Microsoft issues bug fixes and system upgrades on a regular basis, which can help to improve your overall system stability, especially for newer hardware.
- You can check for updates in Windows Settings by right-clicking the Start menu and pressing the Settings option. In the Windows Settings menu, press Update & Security > Windows Update > Check for updates to check and install any of the latest system updates for your PC.
Once updated, restart your PC to see if the updates have any impact on the dwm.exe process.
Check for Graphics Driver Updates
If Windows is up-to-date, your next step is to ensure that your graphics drivers are up-to-date, too. You may find that you need to check the manufacturer’s website for the latest driver releases, as drivers often reach the Windows update system much later.
For instance, NVIDIA card owners would need to check the NVIDIA website to get the latest updates, which are often released alongside major game or hardware releases. These come with the latest bug fixes, too, which can help to solve unusual problems like high CPU usage.
Check Your Graphics Card Is Being Used
If you’ve installed a new graphics card and the drivers are updated, you should also check that the card is being used correctly.
If you’ve connected your monitor cable to your motherboard and not your graphics card by mistake, your graphics card will be ignored. This could result in Windows defaulting to software acceleration for visual effects instead.
- You can double-check if this is the case in the Windows Task Manager. Right-click the taskbar and click Task Manager to open this, then press the Performance tab in the Task Manager window.
Devices with more than one GPU (for instance, PCs with a built-in GPU on the motherboard and an external graphics card) will be shown here, listed as GPU 0, GPU 1, etc. If the resource usage for the internal graphics chip is higher, this would mean your graphics card isn’t being used.
To help resolve this, check the connections between your monitor and your graphics card to ensure that the correct device is being used.
Scan Windows for Malware
If your system is up-to-date and working correctly, then high CPU usage could point to a malware infection.
Make sure to scan Windows 10 for malware thoroughly, including running a boot-level scan using Windows Security or another antivirus. If you’re worried that the dwm.exe process isn’t the official system process, you can double-check in Windows Task Manager.
- To do this, right-click the taskbar and select Task Manager, then find the running Desktop Window Manager process, listed under the Processes tab in the Task Manager window. Press the Open file location option to open the location of that running file in Windows File Explorer.
This will take you to the location of the Desktop Window Manager process. If the file location isn’t the C:\Windows\System32 folder, then the running process isn’t the official dwm.exe file.
If this is the case, run another malware scan and, if nothing else works, you may need to think about giving Windows a factory reset to ensure you have a fresh configuration.
Other Important System Processes in Windows 10
The Desktop Window Manager (dwm.exe) process is just one of many important system processes that you might not have previously heard of. Like svchost.exe and others, dwm.exe can sometimes be associated with spikes in CPU usage. But in many cases, this can be fixed by updating your PC and checking for malware.
While it isn’t possible to disable dwm.exe, you can switch off some of the newer Windows 10 visual effects in Windows Settings. This may help to deal with CPU spikes if malware isn’t the cause. But you may need to look at alternatives, including upgrading your hardware, if your PC is struggling.
