在 Windows 10 中，文件资源管理器^{(File Explorer)}向我们展示了存储在系统硬盘上的视频和图像的微小预览。我们大多数人习惯于通过查看缩略图预览来浏览我们的收藏。

这是因为这些缩略图让我们可以快速浏览文件资源管理器的内容，并且我们不需要打开每个可能具有混淆文件名的文件。缩略图预览^{(Thumbnail previews)}使导航过程显着加快，但它也带来了一系列问题，可能会鼓励您在Windows 10系统上禁用此功能。

在此基础上，了解如何在Windows 11/10中启用和禁用缩略图预览。

在资源管理器^(Explorer)中禁用缩略图预览^{(Thumbnail Previews)}

缩略图^(Thumbnail)预览是一项非常有用的功能，因为它们让您无需打开即可查看 Windows 文件。文件资源管理器^{(File Explorer)}的内容可以设置为超大图标、大图标、中图标和细节/磁贴视图，非常适合喜欢有条理的人。但正如我所说，它带来了自己的一系列麻烦。创建用于快速导航/预览文件的缩略图会减慢其他文件操作，影响系统性能，并导致 UI 混乱。在这种情况下，禁用该功能是个好主意。

如果您的图像或其他文件显示通用Windows图标，例如图像的山景和湖景或视频文件的媒体播放器图标，则缩略图预览^{(Thumbnail Previews)}功能可能已禁用。另一方面，如果您可以查看文件内容的小快照，则启用该功能。

以下是启用和禁用缩略图显示功能的不同过程：

通过文件资源管理器选项
使用控制面板
使用注册表编辑器
通过性能选项
使用组策略编辑器。

这些过程将在下面更详细地描述。

1]通过文件资源管理器^{(File Explorer)}选项启用^(Enable)或禁用缩略图预览

禁用缩略图预览资源管理器

要禁用，请执行以下步骤：

单击“确定”^(Ok’)和“应用^(Apply)”设置。

要启用^(enable)，请按照上述相同的过程直到步骤“ 3”，然后取消选中“始终显示图标，从不缩略图^{(Always show icons, never thumbnails)}”选项。

2]通过控制面板^{(Control Panel)}显示缩略图^{(Show Thumbnail)}预览

禁用缩略图预览

要启用，请执行以下步骤：

从“开始菜单^{(Start Menu)}”转到“控制面板^{(Control Panel)}”
点击“系统和安全^{(System and Security)}”并点击“系统^(System)”。
选择左侧面板上出现的“高级系统设置”。^{(Advance System Settings)}
在“系统属性^{(System Properties)}”窗口中，单击“性能^{(Performance)}”标题下的“设置”。^(Settings)
现在在“性能选项^{(Performance Options)}”对话框中，单击“视觉效果^{(Visual Effects)}”选项卡

按“确定”^(OK’)和“应用^(Apply)”保存更改。

要通过控制面板^{(Control Panel)}禁用缩略图预览，请取消选中“自定义：^(Custom:) ”标题下的“显示缩略图而不是图标”。^{(Show thumbnails instead of icons)}

3]使用注册表编辑器

1]按“ Windows key + R ”打开“运行”^(Run’)对话框。

键入“ SystemPropertiesPerformance.exe ”并按“ Enter”。
现在，选中或取消选中“显示缩略图而不是图标^{(Show thumbnails instead of icons)}”选项以启用或禁用Windows 10中的缩略图预览。

5]使用组策略编辑器

您可以使用组策略编辑器^{(Group Policy Editor)}来启用/禁用此功能。跟着这些步骤：

1] 按“ Win + R ”键打开“运行”^(Run’)对话框。

2] 现在，输入“ gpedit.msc ”并按“ Enter ”。

3]当窗口打开浏览器到以下路径：

User Configuration > Administrative Templates > Windows Components > File Explorer

4]现在，在窗口的右侧，双击“关闭缩略图的显示，只显示图标”^{(Turn off the display of thumbnails and only display icons’)}

5]单击“启用”^(Enabled’)或“禁用”^{(Disabled’)}以打开/关闭该功能。

您现在应该能够轻松启用缩略图预览。

文件资源管理器^{(File Explorer)}中仍未显示缩略图

Windows上的缩略图预览通常使用缩略图缓存。因此^(Hence)，如果缩略图缓存损坏，则可能会出现此问题，因此必须清除缩略图缓存。

这篇文章将说明如果缩略图预览未在 Windows 文件资源管理器中^{(Thumbnail Previews not showing in Windows File Explorer)}显示该怎么办。

请让我们知道这是否是一次顺利的体验。^{(Do let us know if it was a smooth experience.)}

Enable or Disable Thumbnail Previews in File Explorer in Windows 11/10

In Windоws 10, the File Explorer shows us tiny previews for videos and images that are stored on our system’s hard disk. Most of us are accustomed to browsing through our collection by looking at the thumbnail previews.

This is because these thumbnails give us a quick walk through the contents of the file explorer, and we do not need to open every single file that may have confusing file names. Thumbnail previews make the navigation process notably fast, but it comes with its own set of troubles that may encourage you to disable this feature on your Windows 10 system.

Building on this, understand how to enable and disable thumbnails previews in Windows 11/10.

Disable Thumbnail Previews in Explorer

Thumbnail previews can be a very useful feature as they let you view Windows files without opening them. The content of the File Explorer can be set to extra-large icons, large icons, medium icons, and details/tiles view, it is great for those who like to be organized. But as I said it brings its own set of troubles. The creation of thumbnails for quick navigation/previewing of files slows down the other file operations, affects system performance, and causes UI clutter. In such a case, disabling the feature is a good idea.

If your images or other files are displaying a generic Windows icon like mountain and lake scene for images or media player icon for video files, probably the Thumbnail Previews feature is disabled. On the other hand, if you can view a small snapshot of the content of the file the feature is enabled.

Here are different processes to enable and disable the thumbnail display feature:

Via File Explorer Options
Using Control Panel
Using the Registry Editor
Via Performance options
Using the Group Policy Editor.

These processes are described in more detail below.

1] Enable or disable thumbnail previews via File Explorer Options

Now check the ‘Always show icons, never thumbnails’ option appearing under ‘Advanced Settings’.

Press ‘OK’ and ‘Apply’ to save changes.

To disable thumbnail previews via Control Panel, uncheck the ‘Show thumbnails instead of icons’ under the ‘Custom:’ heading.

Thumbnails still not showing in File Explorer

The thumbnail preview on Windows normally uses thumbnail cache. Hence, if the thumbnail cache gets corrupted this issue may occur, and clearing the thumbnail cache becomes imperative.
