Customize your windows by resizing the scroll bar

The customization is one of the most important aspects for users of Windows. We all like to adapt the appearance of the operating system to our tastes. We change the desktop background, the colors, the icons, the sounds, and everything we can, to feel as comfortable as possible when using our PC. However, the customization possibilities of Windows can go much further, although the truth is that Microsoft does not put it exactly in view. For example, we can customize the size of the scroll bar, or scroll, of the windows so that they take up less space or be able to see them better.

The Windows scroll bar is the bar that appears to the right of each window (even the web browser) and that allows us to scroll vertically (or horizontally) through all the content within that window. If we have a very long list of elements, for example, we can move through all of it with this bar, in addition to using the mouse wheel.

Although Microsoft is bringing many options to the Settings menu of the operating system, we often find functions and settings that are not yet in this Settings menu. For example, the ability to adjust the size of this scroll bar in our Windows windows. Therefore, if we want to change its size, it is necessary to resort to a simple change in the Windows registry.

Resize the Windows scroll bar

To make this change in the configuration, the first thing we will do is enter the Windows registry. For this we will use the Cortana search engine, or we will press the keyboard shortcut Windows + R and execute the command:


Within the Windows registry editor, we move to the following section:

HKEY_CURRENT_USER \ Control Panel \ Desktop \ WindowMetrics

Here we will find two values: ScrollHeight and ScrollWidth. These two will be the ones that allow us to modify these values ​​(although we must know how to enter the appropriate value).

By default, these values ​​have a value of -255. This value is obtained by multiplying -15 by the value, in pixels that we want the scroll bar to have. By default, the value it has is 17 pixels (-15 × 17 = -255). In case we want this bar to have a thickness of 10 pixels, what we must do is change the values ​​for the number, in negative, that corresponds (-15 × 10 = -150). If we want it fatter, at 20 pixels, then we change the value to (-15 × 20 = -300).

These registry entries support values ​​from -120 (the thinnest) to -1500 (the thickest).

We restart the computer after changing the values ​​and, when we open a new Windows file explorer window, we will have the new value assigned to the PC.

Return to the original size of the scroll bar

We may not finish finding the optimal value the first time. Nothing happens. We simply have to go back to the registry and change the value of these two entries to another value and restart to see the changes.

In the event that none of the settings convinces us, what we must do is restore the default value to the two registry entries. That is, we will give ScrollHeight and ScrollWidth a value of -255 (negative value, important).

We accept the changes, restart the PC and we will have the Windows 10 scroll bar back in its default size and thickness.

This trick works on all versions of Windows 10, from the first to the 2004 version of the operating system that will arrive in spring 2020.
