What happens when a person with fat fingers touches a scroll bar, trying to move it up or down or across. Little success he gets, isn’t it? This has been the problem bothering some people for a long while working on touch-sensitive Windows 8 laptops or tablets. The Scroll bar is a vertical or horizontal bar that appears when scrolling the content. It is visible to the extreme sides of the screen and sometimes at the bottom of the screen. If you find the Windows 8 scroll bar hard to see or to use, you can if you wish, change the Windows 8 Scrollbar width.
Here’s how you can change the scroll bar width in Windows 8.1.
Change Windows 8 Scrollbar Width
Press Win+R in combination to bring up the Run dialog box. In the dialog box that appears, type REGEDIT and hit the OK button. If prompted by UAC, click on Yes.
Now, in the Windows Registry window that opens navigate to the following location -
Select the key and in the right pane of WindowsMetrics, double-click ‘ScrollHeight’ word.
Instantly, a window should appear on your computer screen (EDIT DWORD). In the value data field of the window, enter a data value. The default value for scroll width is the -225. Entering 500 will double the width, which should be fine in my opinion. But you can enter any value up to 1500. You could say, enter 1400 to make it even bigger. Remember, more or higher the value, the wider is the scrollbar.
Next, double tap on ScrollWidth in the right pane of WindowMetrics. In EDIT DWORD window, enter the same data value as entered for “ScrollHeight” and tap OK.
Now close Windows Registry Editor. For changes to apply, you’ll need to sign out and sign-in, back to your user account. Open File Explorer and you will find that the scroll bar width has been changed.
This should resolve your problem. Now, you can easily move the scroll bar up-down or sideways easily, without much efforts.
