How to reverse the scroll button?

Step 1: Install AutoHotkey on your Windows PC.
Step 2: Launch AutoHotkey, and when prompted to create a sample script, click the Yes button. Step 3: When the sample script appears in Notepad, paste the following code just below the two sample hotkeys:

WheelUp::
Send {WheelDown}
Return

WheelDown::
Send {WheelUp}
ReturnStep 4: Save the script in Notepad (Ctrl+S). That's it. Now scrolling on your Windows touch pad or mouse will be reversed. To enable the script on reboot, just copy the AutoHotkey shortcut to your Startup folder. If you end up using AutoHotkey for other scripts, just copy the shortcuts to the scripts themselves into the Startup folder. To disable reverse scrolling, edit the code out of the script or uninstall AutoHotkey entirely.
