如果您打开任务管理器^{(open Task Manager)}，您可能会看到一个名为splwow64.exe的进程正在您的 Windows 10 设备上运行。您可能想知道这个过程的全部内容以及为什么它会在您的设备上运行。在这篇文章中，我们解开了Windows 10上的^{(Windows 10)}splwow64.exe进程以及如何禁用它。

什么是 Windows 10 上的 splwow64.exe 进程

如上图所示，列出了 splwow64.exe 进程的“后台^(Background)进程”部分详细介绍了桌面上可能不可见的程序。其中包括由其他程序安装的进程，例如自我更新实用程序、Windows组件和“暂停”的Windows 应用商店^{(Windows Store)}应用程序。

我们将在本节的以下小标题下讨论这个主题：

什么是任务管理器^{(Task Manager)}中的 splwow64.exe，它为什么会运行？

splwow64.exe是Microsoft自己创建的Windows进程，用于连接和管理打印机后台处理程序服务。任务管理器^{(Task Manager)}中的这个特定进程被列为32 位应用程序的打印机驱动程序主机^{(Printer driver host for 32-bit applications)}。这意味着，splwow64.exe进程用于连接64 位 Windows 操作系统^{(64-bit Windows OS)}上的 32 位打印机应用程序。当您的设备使用 32 位打印机驱动程序时， Windows会自动触发splwow64.exe进程——该进程应该在打印作业完成后立即自行终止。^{(splwow64.exe)}

因此，如果您的设备连接到 32 位打印机并且在任务管理器^{(Task Manager)}中，splwow64.exe进程正在运行，则无需担心。但是，如果没有连接打印机并且 splwow64.exe 进程似乎在任务管理器^{(Task Manager)}中持续运行，那么您应该删除该进程，以防止它可能在您的设备上导致任何潜在的性能问题。

禁用打印后台^{(Print Spooler)}处理程序以终止 splwow64.exe 进程

有时，Splwow64.exe进程会在内存中停留额外时间，以在打印作业完成后提高系统性能。打印作业完成后，它不会按预期结束。你有两个选择：

• 禁用后台打印程序启动类型
• 更改超时值。

预期的正常行为是splwow64.exe进程应在您的打印作业完成后立即自动终止 - 但如果该进程仍在任务管理器^{(Task Manager)}中运行，它可能会成为错误并可能在您的设备上崩溃 - 为了防止这种情况，您需要将Print Spooler Startup type值设置为Disabled以终止 splwow64.exe 进程。就是这样：

• 按Windows key + R调用“运行”对话框。
• 在“运行”对话框中，键入services.msc并按 Enter 以打开服务控制台^{(open Services console)}。
• 在“服务”窗口中，找到 Print Spooler 服务。
• 双击Print Spooler以编辑其属性。
• 在“属性”窗口中，单击“启动类型^{(Startup type)}”并从下拉列表中选择“禁用”选项。^(Disabled)
• 单击应用^(Apply)>确定^(OK)以保存更改。
• 退出服务窗口。
• 重新启动计算机。

开机后，打开任务管理器^{(Task Manager)}，查看splwow64.exe进程是否还在后台运行。

如果您经常看到这种情况发生，您还可以配置其超时值^{(configure its time-out value)}，如下所示：

打开注册表编辑器^{(Registry Editor)}并导航到以下键：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print

创建一个新的 DWORD 值，将其命名为SplWOW64TimeOutSeconds并在其中输入一个大于 0 的值。

微软说，

The Splwow64.exe process is unloaded when the number of seconds that is specified in SplWOW64TimeOutSeconds elapses since the last 32-bit print process has closed. Therefore, when a service process prints, the print capability is not released until the service closes and at least the time that you specify in the Value data box passes. For example, if you type 15 in the Value data box, and the last 32-bit process takes two minutes to print and close, the print capability is released between two minutes and 15 seconds and two minutes and 30 seconds. If no time-out value is specified, the default time-out value is two minutes.

希望这可以帮助。

What is splwow64.exe process in Windows 10 and Can I disable it?

Іf you open Task Manager, you might see a process named splwow64.exe running on your Windows 10 device. You may be wondering what this process is all about and why is it running on your device. In this post, we unravel the splwow64.exe process on Windows 10 and how to disable it.

What is splwow64.exe process on Windows 10

As shown on the lead-in image above, the Background processes section where the splwow64.exe process is listed, details programs that probably aren’t visible on your desktop. These include processes installed by other programs, such as self-update utilities, Windows components, and “suspended” Windows Store apps.

We will discuss this topic in this section under the following subheadings:

What is splwow64.exe in Task Manager and why is it running?

The splwow64.exe is a Windows process created by Microsoft itself that is meant for connecting and managing printer spooler services. This particular process in the Task Manager, is listed as Printer driver host for 32-bit applications. What this means, is that, the splwow64.exe process is used for connecting 32-bit printer applications on a 64-bit Windows OS. The splwow64.exe process is automatically triggered by Windows when your device is using 32-bit printer drivers – the process is supposed to terminate itself as soon as the printing job is done.

So, if your device is connected to a 32-bit printer and in Task Manager, the splwow64.exe process is running, then there’s nothing to worry about. However, if there’s no printer connected and it appears that the splwow64.exe process is persistently running in Task Manager, then you should get rid of the process so as to prevent any potential performance issue it might cause on your device.

Disable Print Spooler to terminate splwow64.exe process

At times, the Splwow64.exe process stays in the memory for additional time to increase system performance after a print job is finished. It does not end as expected when a print job is finished. You have two options:

• Disable Print Spooler Startup type
• Change Timeout value.

The expected normal behavior is that the splwow64.exe process should terminate automatically as soon as your print job completes – but if the process is still running in the Task Manager, it might become an error and can crash on your device – to prevent this, you need to set the Print Spooler Startup type value to Disabled to terminate the splwow64.exe process. Here’s how:

• Press Windows key + R to invoke the Run dialog.
• In the Run dialog box, type services.msc and hit Enter to open Services console.
• In the Services window, locate the Print Spooler service.
• Double-click Print Spooler to edit its properties.
• In the Properties window, click Startup type and select the Disabled option from the drop-down list.
• Click Apply > OK to save changes.
• Exit Services window.
• Reboot computer.

On boot, open Task Manager and check whether the splwow64.exe process is still running in the background.

If you see this happening frequently, you can also configure its time-out value as follows:

Open Registry Editor and navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print

Create a new DWORD Value, name it SplWOW64TimeOutSeconds and enter a value greater than 0 in it.

Says Microsoft,

The Splwow64.exe process is unloaded when the number of seconds that is specified in SplWOW64TimeOutSeconds elapses since the last 32-bit print process has closed. Therefore, when a service process prints, the print capability is not released until the service closes and at least the time that you specify in the Value data box passes. For example, if you type 15 in the Value data box, and the last 32-bit process takes two minutes to print and close, the print capability is released between two minutes and 15 seconds and two minutes and 30 seconds. If no time-out value is specified, the default time-out value is two minutes.

Hope this helps.
