Hello getaman,
Some programs will give you an option to "Install for all users" during installation that will place a shortcut of the program in all users Start Menu.
There is two Start Menu folders. One the is for the specific user, and one that's shared by all users. The shortcuts from both folders show in the same Start Menu.
If you like, you could user OPTION TWO in the tutorial below to add or remove shortcut for all users, and use OPTION ONE to add or remove shortcut for a specific user.
Start Menu All Programs - Add or Delete Shortcuts
Hope this helps,

Shawn
