How to Change Mouse Scroll Speed in Windows 10

Here’s how you can do this task:

Press Windows + I to open Settings.

Click on Devices.

Hit the Mouse on the left sidebar.

Below Mouse pointer speed, you’ll find a “Roll the mouse wheel to scroll” drop-down menu.

Open it and select what you want your mouse wheel to scroll. The options are “Multiple lines at a time” and “One screen at a time.”

If you select the former, then you can adjust each time how many lines will scroll using the slider between the drop-down list and Scroll inactive windows when I hover over them.

Note: If you wish to change the horizontal scrolling setting, see the section below.

Alternate Methods

Method #1

Launch Mouse Properties

Navigate to the “Wheel” tab. 

In the “Vertical Scrolling” section, you have two options: “The following number of lines at a time” and “One screen at a time.”

You can select the option based on what you want your mouse wheel to scroll. Selecting the former, you can customize the number of lines that scroll each time using the box beneath it.

Under “Horizontal Scrolling,” you can customize how many characters will scroll every time.

After setting these up as per your preference, click “OK” at the bottom.

Method #2

Start Registry Editor. Before proceeding, I suggest you backup the Registry.

Go to HKEY_CURRENT_USER > Control Panel > Desktop.

Double-click the WheelScrollLines in the right pane.

In the Value data field, enter any value between 1 and 100. Remember that the value represents the line.

In the Value data field, you need to enter -1 if you want to scroll one screen at a time.

Click the OK button.

For horizontal scrolling, you need to double-click WheelScrollChars.

In the Value data field, provide any value between 1 and 100. Remember that the value represents the character.

Click the OK button.

Sign out and then sign back in.

That’s it.

Note: The “Horizontal Scrolling” setting is for mice that support horizontal scrolling.
