Windows操作系统会随着时间的(Windows)推移而发生变化，它不会保持静止。它的外观和工作方式通常会因版本而异。
Windows 11中的滚动条也不例外。您可能会发现Windows 11中的滚动条太细而无法使用，或者根本不显示，默认情况下显示为隐藏。如果您想更改此行为，您需要了解如何在Windows 11电脑上自定义滚动条（特别是如果您使用的是触摸屏设备）。
您可以通过多种方式自定义Windows 11滚动条，从使其始终可见到更改其大小和行为。我们将在下面解释如何进行。
如何使滚动条始终可见(Scrollbars Always Visible)
大多数 Windows 11 应用程序中的默认行为是滚动条显示为隐藏。您必须将鼠标悬停在窗口边缘或在屏幕上滑动手指才能显示它们。这可能会令人沮丧且耗时，尤其是当您积极尝试滚动浏览较长的文档或网站时。
要使滚动条在Windows 11上始终可见，您可以使用辅助功能设置。就是这样：
- 右键单击(Right-click)“开始”(Start)菜单，然后按“设置”。
- 在“设置”(Settings)应用程序中，从左侧边栏中选择“辅助功能” 。(Accessibility)在右侧，选择视觉效果部分。
- 在“视觉效果”菜单中，切换“始终(Always)显示滚动条”选项。
这将使滚动条永久显示在受支持的Windows应用程序中，包括记事本(Notepad)、写字板(WordPad)和其他默认的 Microsoft 应用程序(default Microsoft apps)。要将来隐藏它们，请返回设置菜单并禁用“始终(Always)显示滚动条”滑块。
它还可能会影响滚动条在其他非 Microsoft 应用程序中的显示方式。但是，这取决于您使用的应用程序，并且您的体验可能会有所不同。
如何更改Windows 11滚动条(Scrollbars)的大小(Size)
如果您想自定义Windows 11滚动条，使其看起来比默认大小更小或更大，那么只有一种方法可以在不使用第三方软件的情况下完成此操作：通过 Windows注册表(Windows Registry)。通过修改注册表(modifying the Registry)，您将能够通过注册表(Registry)项更改来设置滚动条的大小。
不过，有一句警告。更改注册表可能(Registry)会对您的计算机造成危险，因为错误的更改可能会导致您的 PC 变得不稳定或停止工作。
在开始之前，请确保备份注册表(backup your Registry)以便于恢复。您还应该创建一个新的系统还原点，(create a new System Restore point)以确保在出现问题时可以恢复您的电脑。
要使用注册表编辑器(Registry Editor)更改 Windows 11（或 Windows 10）上滚动条的大小，请按照以下步骤操作：
- 右键单击(Right-click)“开始”(Start)菜单并选择“运行”(Run)以打开“运行”(Run)对话框。或者，同时按Windows键 + R。
- (Type)在“运行”框中(Run)键入regedit ，然后单击“确定”。
- 如果出现提示，请按“是”接受“用户帐户控制”(User Account Control)提示。
- 在注册表编辑器(Registry Editor)窗口中，使用左侧的导航树菜单或顶部的栏
导航到Computer\HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics
- 在右侧，双击ScrollHeight值。这将允许您修改 Windows 11 PC 上的滚动条高度。
- 在“编辑字符串”(Edit String)对话框中，将“值”数据更改为(Value)-100和-1500之间的负数。数字越小，滚动条越大。例如，-100 0 将产生一个非常大的滚动条，而-150 将产生一个非常小的滚动条。默认值为-255。
- 单击“确定”保存更改。
- (Repeat)对ScrollWidth值(ScrollWidth)重复这些步骤，将值设置在-100和-1500之间。这将修改Windows 11滚动条宽度。
- 关闭注册表编辑器并重新启动计算机(restart your computer)以使更改生效。
您现在应该看到滚动条的大小已更改。如果您不满意，请重复这些步骤以增加（或减少）滚动条，或者通过将ScrollHeight(ScrollHeight)和ScrollWidth值更改回-255 来恢复默认(-255)大小。
如何在Windows 11上(Windows 11)调整鼠标滚动行为(Adjust Mouse Scrolling Behavior)
大多数用户不会主动向上或向下拖动滚动条 - 他们使用鼠标来实现他们想要的滚动效果。在Windows 11(Windows 11)上自定义滚动条的另一种方法是调整鼠标与滚动条交互时（或如何）的行为。
例如，您可以启用或禁用非活动窗口上的滚动，这意味着您可以滚动任何窗口而无需先单击它，从而使其成为“活动”窗口。这对于多任务处理或比较不同的文档或网页时非常有用（只要鼠标滚动可以(as long as mouse scrolling works)在您的电脑上运行）。
要调整Windows 11(Windows 11)上的滚动行为，您需要调整鼠标设置。就是这样：
- 右键单击(Right-click)“开始”(Start)菜单并选择“设置”(Settings)。
- 在“设置”(Settings)应用中，使用左侧边栏打开“蓝牙(Bluetooth)和设备”> “鼠标” 。(Mouse)
- 在右侧窗格的“滚动”(Scrolling)部分下，切换“将鼠标(Scroll)悬停在非活动窗口上方时滚动非活动窗口”选项的开关，以启用或禁用该功能。
更改将立即应用 - 您无需重新启动电脑。如果您想恢复原状，请返回菜单并禁用（或重新启用）该功能。
自定义您的 Windows 11 电脑
在Windows 11(Windows 11)电脑上滚动页面或应用程序的方式没有正确或错误之分。如果您想自定义Windows 11上的滚动条以满足您自己的要求，上述步骤将帮助您完成工作。
您是否(Did)知道您甚至不需要滚动浏览网页？您可以使用不同的浏览器扩展或附加组件
将鼠标设置为自动滚动。(set your mouse to scroll automatically)
然而，如果您使用的是触摸屏设备，由于两指滚动，滚动可能会容易得多。但是，如果两指滚动不起作用(two-finger scrolling isn’t working)，您接下来需要解决该问题。
How to Customize the Scrollbar in Windows 11
The Windows operating system changes over time—it doesn’t remain static. Hоw it looks and works can often change from one version to the next.
Scrollbars in Windows 11 are no different. You might find that the scrollbar in Windows 11 is too thin to use, or doesn’t appear at all, appearing hidden by default. If you want to change this behavior, you’ll need to know how to customize the scrollbar on your Windows 11 PC (especially if you’re using a touchscreen device).
There are a few ways you can customize your Windows 11 scrollbars, from making them always visible to changing their size and behavior. We’ll explain how below.
How to Make the Scrollbars Always Visible
The default behavior in most Windows 11 applications is for the scrollbar to appear hidden. You’ll have to hover your mouse over the edge of the window or swipe your finger on the screen to reveal them. This can be frustrating and time-consuming, especially if you’re actively trying to scroll through a long document or website.
To make the scrollbars always visible on Windows 11, you can use the accessibility settings. Here’s how:
- Right-click the Start menu and press Settings.
- In the Settings app, select Accessibility from the left-hand sidebar. On the right, select the Visual effects section.
- In the Visual effects menu, toggle the Always show scrollbars option.
This will make the scrollbars appear permanently in supported Windows apps including Notepad, WordPad, and other default Microsoft apps. To hide them in the future, return to the settings menu and disable the Always show scrollbars slider.
It may also impact how scrollbars appear in other non-Microsoft apps. However, this will depend on the application you’re using, and your experience may vary.
How to Change the Size of Windows 11 Scrollbars
If you want to customize the Windows 11 scrollbar so that they appear smaller or larger than the default size, there’s only one way to do it without third-party software—via the Windows Registry. By modifying the Registry, you’ll be able to set the size of your scrollbars via a Registry key change.
A word of warning, however. Making changes to the Registry is potentially dangerous to your computer, as the wrong change can cause your PC to become unstable or stop working.
Before you begin, make sure that you backup your Registry to allow you to restore it. You should also create a new System Restore point to ensure you can restore your PC if something goes wrong.
To change the size of the scrollbars on Windows 11 (or Windows 10) using the Registry Editor, follow these steps:
- Right-click the Start menu and select Run to open the Run dialog box. Alternatively, press the Windows key + R together.
- Type regedit in the Run box and click OK.
- If prompted, press Yes to accept the User Account Control prompt.
- In the Registry Editor window, navigate to the Computer\HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics key using the navigation tree menu on the left or the bar at the top.
- On the right, double-click the ScrollHeight value. This will allow you to modify the scrollbar height on your Windows 11 PC.
- In the Edit String dialog box, change the Value data to a negative number between -100 and -1500. The lower the number, the bigger the scrollbar. For example, -1000 will make a very large scrollbar, while -150 will make a very small scrollbar. The default value is -255.
- Click OK to save your changes.
- Repeat these steps for the ScrollWidth value, setting the value between -100 and -1500. This will modify the Windows 11 scrollbar width.
- Close the Registry Editor and restart your computer for the changes to take effect.
You should now see that your scrollbars have changed their size. If you’re unhappy, repeat these steps to increase (or decrease) the scrollbars, or revert back to the default size by changing the ScrollHeight and ScrollWidth values back to -255.
How to Adjust Mouse Scrolling Behavior on Windows 11
Most users don’t actively drag a scrollbar up or down—they use their mouse to achieve the scrolling effect they want. Another way to customize the scrollbars on Windows 11 is to adjust how they behave when (or how) your mouse interacts with them.
For instance, you can enable or disable scrolling on inactive windows, which means that you can scroll through any window without clicking on it first, and thus making it the ‘active’ window. This can be useful for multitasking or when you’re comparing different documents or web pages (as long as mouse scrolling works on your PC).
To adjust the scrolling behavior on Windows 11, you’ll need to adjust your mouse settings. Here’s how:
- Right-click the Start menu and select Settings.
- In the Settings app, open Bluetooth & devices > Mouse using the left-hand sidebar.
- On the right pane, under the Scrolling section, toggle the switch for the Scroll inactive windows when hovering over them option to enable or disable the feature.
The change will apply immediately—you won’t need to restart your PC. If you want to revert back, return to the menu and disable (or re-enable) the feature.
Customizing Your Windows 11 PC
There’s no right or wrong way to scroll through pages or applications on your Windows 11 PC. If you want to customize the scrollbar on Windows 11 to suit your own requirements, the steps above will help you to get the job done.
Did you know that you didn’t even need to scroll yourself to work through a webpage? You can set your mouse to scroll automatically by using different browser extensions or add-ons.
If you’re using a touchscreen device, however, scrolling might be a lot easier, thanks to two-finger scrolling. However, if two-finger scrolling isn’t working, you’ll need to troubleshoot the problem next.
