We changed the default in Start11 as the right click menu on the start button in Win11 offers access to a number of important features.
You can access Start11 settings in two other ways.
1) Run the Start11 link in the all programs list under stardock
2) Right clicking on a blank area of the Start11 menu will show a menu offering configure Start11 option.
You can also switch the default back to how it was in Start10 for the start button if you wish from the setting screen. Pick Taskbar and then advanced options at the bottom and there is a setting called "Show Win+X menu when right clicking on the start button". Turn that off and things are back to how they used to be with Start10.
