Disabling The Mouse Wheel

The mouse wheel has become a ubiquitous feature which assists greatly in web browsing, and navigating documents. However some applications respond badly or non-intuitively to the mouse wheel — for example they may navigate to the next record instead of scrolling the display down, as users may expect. Additionally, some users may find it difficult to use the mouse without accidentally triggering the wheel, resulting in unexpected actions in the application.

Normally the sensitivity of the mouse wheel can be controlled under Control PanelMouseWheel; configure as required. However the wheel can't be disabled from this interface because the dialog box won't accept 0 as an option for the scrolling response.

To set the scroll to zero and effectively disable the mouse wheel, open a command prompt and type:

reg add "HKCU\Control Panel\Desktop" /v WheelScrollLines /d 0 /f /t REG_SZ

Log out and log back in for the change to take effect.

Note that if you change the settings in the Mouse Control Panel applet, the setting may be reset.
