当您将鼠标光标放在文件或文件夹上时，它会弹出一个显示与之相关的信息的弹出窗口。该操作可能需要在默认400毫秒到1000毫秒之间的任何时间。这称为鼠标悬停时间^{(Mouse Hover Time)}，允许鼠标指针在触发操作之前保持悬停在项目上。在Windows 10中，有一个设置可让您更改鼠标悬停^{(Mouse Hover)}时间。阅读它是如何完成的！

如何在Windows 10中更改^{(Windows 10)}鼠标悬停时间^{(Mouse Hover Time)}

更改鼠标悬停时间对任务栏^(Taskbar)缩略图预览和文件资源管理器^{(File Explorer)}中的文件选择都有影响。例如，当您增加鼠标悬停时间并将鼠标光标悬停在Windows 10 任务栏中^(Taskbar)打开的程序上时，它将显示预览，但会延迟几毫秒。

1. 打开注册表编辑器。
2. 转到Control Panel\Mouse。
3. 在鼠标^(Mouse)键的右窗格中，双击MouseHoverTime。
4. 输入鼠标悬停时间所需的时间（以毫秒为单位）。
5. 单击确定。
6. 关闭注册表编辑器
7. 重新启动您的电脑。

请^(Please)注意，该方法涉及对注册表编辑器^{(Registry Editor)}进行更改。如果您不正确地更改注册表编辑器，可能会发生严重的更改。^{(Registry Editor)}在继续进行更改之前创建一个系统还原点。

Press Win+R打开“运行”^(Run)对话框。

当注册表编辑器^{(Registry Editor)}打开时，导航到以下路径地址 -

HKEY_CURRENT_USER\Control Panel\Mouse.

切换到鼠标^(Mouse)键的右窗格并双击MouseHoverTime字符串值 (REG_SZ)。

出现“编辑字符串^{(Edit String)}”框时，输入鼠标悬停时间所需的毫秒数。默认时间设置为 400 毫秒。

您可以将此时间限制延长至 1000 毫秒，这与 1 秒相同。

完成后，关闭注册表编辑器^{(Registry Editor)}并退出。

重新启动您的 PC 以使更改生效。

How to change Mouse Hover Time in Windows 10

When you drop the mouse cursor over a fіle or folder, іt brings up a pop-up that displays the information relаted to it. Τhe action can take tіme anywherе between the default 400 milliseconds to 1000 milliseconds. This is called Mouse Hover Time and allows the mouse pointer to stay hovered over an item before an action is triggered. In Windows 10, there’s a setting that lets you change the Mouse Hover time. Read how it’s done!

How to change Mouse Hover Time in Windows 10

Changing the mouse hover time has an influence on both, the Taskbar thumbnail preview and file selection in File Explorer. For example, when you increase the mouse hover time and hover the mouse cursor over an open program in Windows 10 Taskbar, it will show a preview but after a few milliseconds of delay.

1. Open the Registry Editor.
2. Go to Control Panel\Mouse.
3. In the right pane of the Mouse key, double click the MouseHoverTime.
4. Enter time in milliseconds you want for the mouse hover time.
5. Click OK.
6. Close the Registry Editor
7. Restart your PC.

Please note that the method involves making changes to the Registry Editor. Serious changes can occur if you make changes to the Registry Editor incorrectly. Create a System Restore Point before proceeding further and making changes.

Press Win+R in combination to open the Run dialog box.

When the Registry Editor opens, navigate to the following path address –

HKEY_CURRENT_USER\Control Panel\Mouse.

Switch to the right pane of the Mouse key and double-click the MouseHoverTime string value (REG_SZ).

When the Edit String box appears, type in how many milliseconds you want for the mouse hover time. The default time is set to 400 milliseconds.

You can extend this time limit up to 1000 milliseconds which is the same as 1 second.

When done, close the Registry Editor and exit.

Restart your PC to allow the changes to take effect.
