How do you customize the extra buttons on a *Microsoft Classic Intellimouse* in Windows 10?

Microsoft states that their Classic Intellimouse supports 3 customizable buttons in Windows 7/8/10, except for Windows 10 S. I keep hitting the side buttons and want to disable them.

The default mouse control settings do not offer this. Searching around, I saw the IntelliPoint software should be able to do it.

Intellipoint seems to be no longer supported as the official download says it is compatible up to Windows 7. But I tried version 8.2 anyway and saw that it replaces the stock mouse control panel applet but complains that it can't find a Microsoft mouse. The mouse continues to work, I just can't configure it with the Intellipoint applet. Since the driver is from 2011 I thought I should keep digging.

No other mouse or trackpad drivers are installed on this machine, it's a tower that I built myself using a retail copy of Windows 10. I've tried other USB ports. My other machine here is a laptop that does have a trackpad, so I have not tried it there yet.

I can't find a technical or user manual for the product to direct me where to make the settings changes. Hidden in the very Apple inspired box was a multipage booklet that had nothing but the warranty and regulatory information.

Solution 1:

Edit: The download page referenced originally is gone. Mouse and keyboard Center Download has the current version of the Mouse and Keyboard Center.

I found this Microsoft specifications page about the Classic Intellimouse. It has a download section that points to the Mouse and Keyboard Center 11.

I installed that and it is an application as well as an additional tab with a link to the application in the mouse settings of Windows 10.

From there it was easy to set up the buttons the way I want.

Looking further there is a Mouse and Keyboard Center 12 release, but I'll stick with the one the linked paged offered as it seems the biggest change is additional devices.
