How to set the number of lines that the mouse scrolls once in the Vista system?

When browsing a web page or folder in the Vista operating system, the scroll wheel on the mouse can skip 3 lines each time, which is very sufficient for ordinary users. However, for users with a large amount of browsing, it may be more convenient and quick to adjust to 10 lines per scroll. At the same time, users can adjust this parameter according to their own habits.

Two adjustment methods:

Method 1:

In the control panel, double-click the mouse, you can adjust the number of scrolling lines in the "pulley", as shown below:

Method 2:

3, and then click the right mouse button and select "Edit" on a DWORD value named "WheelScrollLines" editor window on the right. The value I entered here is "10", which means that the mouse is scrolled 10 lines at a time (as shown).

4, After setting, close the window, restart the computer after entry into force.
