如果要更改Windows在^(Windows)Shutdown或Restart关闭应用程序之前等待的时间间隔，则需要编辑HungAppTimeout的值。虽然默认值设置为 5 秒，但您可以根据需要增加或减少此超时。您只需在注册表编辑器中更改^{(Registry Editor)}HungAppTimeout的值数据。

假设有一个或两个应用程序（例如SnagIt、Chrome、Outlook等）处于打开状态，并且您单击了Restart或Shutdown按钮。在这种情况下，Windows可能会显示一条消息，指出这些应用程序已打开并且正在阻止您的系统关闭。尽管可以在Windows 10中禁用^{(Windows 10)}此应用程序正在阻止关闭^{(This app is preventing shutdown)}消息，但您也可以手动更改关闭这些应用程序的超时时间。默认情况下，它会显示一个无论如何^{(Shut down anyway)}都要关闭的按钮，允许用户在不关闭这些应用程序的情况下关闭您的计算机。

更改Windows在^(Windows)关机^(Shutdown)时关闭应用程序之前等待的时间

要更改 Windows 10 在关闭或重新启动时关闭应用程序之前等待的时间，请按照以下步骤操作 -

1. 按 Win+R 打开运行提示。
2. 键入regedit并点击 Enter 按钮。
3. 在 UAC 提示中单击是。
4. 导航^(Navigate)到HKEY_CURRENT_USER中的^{(HKEY_CURRENT_USER)}桌面^(Desktop)文件夹。
5. 双击 HungAppTimeout。
6. 以毫秒为单位设置一个值。
7. 单击确定并关闭注册表编辑器。

由于您要更改注册表编辑器^{(Registry Editor)}中的值，因此最好备份注册表文件^{(backup Registry files)}或创建系统还原点。

^(Press)同时按下Win+R按钮以打开运行^(Run)提示。在这里，您需要输入regedit并点击Enter按钮。您应该会看到UAC提示。如果是这样，请单击是^{(Yes )}按钮以在您的计算机上打开注册表编辑器。

打开注册表编辑器^{(Registry Editor)}后，导航到以下路径-

当前用户：^{(Current user:)}

HKEY_CURRENT_USER\Control Panel\Desktop

所有用户：^{(All users:)}

HKEY_USERS\.DEFAULT\Control Panel\Desktop

在这里，您将找到一个名为HungAppTimeout的^{(HungAppTimeout)}DWORD值。如果您在Desktop^(Desktop)键中看不到此DOWRD值，则需要手动创建它。

为此，右键单击Desktop，选择New > DWORD (32-bit) Value并将其命名为HungAppTimeout。接下来，双击此DWORD值。

默认情况下，它设置为 5000（5 秒）。您需要根据您的要求输入一个值。如果你想要 7 秒，输入 7000。如果你想要 3 秒，输入 3000，依此类推。

最后，单击OK按钮保存更改并关闭注册表编辑器^{(Registry Editor)}。

从现在开始，Windows 10 将等待最近更改的时间，然后再终止应用程序。

Change how long Windows waits before closing apps at Shutdown

If you want tо change the time interval for which Windows waits before closing apps at Ѕhutdown or Restart, you need to edit the value of HungAppTimeout. Although the default value is set to 5 seconds, you can increase or decrease this timeout as per your requirement. All you need to do is to change the value data of HungAppTimeout in Registry Editor.

Let’s assume that one or two apps (eg SnagIt, Chrome, Outlook, etc.) are open, and you click on the Restart or Shutdown button. In such a case, Windows may display a message saying that those apps are open and are preventing your system from shutting down. Although it is possible to disable This app is preventing shutdown message in Windows 10, you can change the timeout for closing those apps manually as well. By default, it shows a Shut down anyway button that allows users to shut down your computer without closing those apps.

Change how long Windows waits before closing apps at Shutdown

To change the time Windows 10 waits before closing apps at shutdown or restart, follow these steps-

1. Press Win+R to open the Run prompt.
2. Type regedit and hit the Enter button.
3. Click Yes in the UAC prompt.
4. Navigate to Desktop folder in HKEY_CURRENT_USER.
5. Double-click on HungAppTimeout.
6. Set a value in milliseconds.
7. Click OK and close Registry Editor.

Since you are going to change values in Registry Editor, it is better to backup Registry files or create a System Restore point.

Press the Win+R buttons together to open the Run prompt. Here, you need to type regedit and hit the Enter button. You should see the UAC prompt. If so, click the Yes button to open Registry Editor on your computer.

After opening Registry Editor, navigate to the following path-

Current user:

HKEY_CURRENT_USER\Control Panel\Desktop

All users:

HKEY_USERS\.DEFAULT\Control Panel\Desktop

Here you will find a DWORD value called HungAppTimeout. If you cannot see this DOWRD value in the Desktop key, you need to create it manually.

For that, right-click on Desktop, select New > DWORD (32-bit) Value and name it as HungAppTimeout. Next, double-click on this DWORD value.

By default, it is set to 5000 (5 seconds). You need to enter a value as per your requirement. If you want to make it 7 seconds, enter 7000. If you’re going to make it 3 seconds, enter 3000 and so on.

At last, click the OK button to save the change and close the Registry Editor.

From now onward, Windows 10 will wait for the recently changed time before killing the app.
