How to Disable Start Menu Auto Expand On Mouse Over in Windows 10

Starting in Windows 10 version 1909, Microsoft made a change to the Start menu. When you hover over the left pane with the mouse pointer, automatically expands itself, revealing the text labels for its items. Personally, I welcome this change and find it useful, but some users do not share my point of view and would like to restore the behavior that previous Windows 10 versions had.


Windows 10 comes with a completely reworked Start menu, which combines Live Tiles introduced in Windows 8 with classic app shortcuts. It has an adaptive design and can be used on displays with various sizes and resolutions.Windows 10 Start Menu

Starting in Windows 10 May 2019 Update, also known as 'version 1903' and '19H1', the Start menu has got its own process that allows it to appear faster, increases its reliability. Besides that, there are a number of usability improvements made to the Start menu.

Windows 10 Start Menu has Live Tile support for Universal (Store) apps installed on your PC. When you pin such an app to the Start menu, its Live Tile will show dynamic content like news, weather forecast, images and so on. For example, you can add a useful data usage Live Tile.

Starting in version 1909, also known as November 2019 Update, the Start Menu expands automatically once you hover over icons on the left. This new behavior is something that some users do not like. Unfortunately, there is no option in Settings to disable it. Instead, we need to use mach2, a freeware tool to unblock hidden features of Windows 10.
