When you install software it often will ask if you want to make it available
to all users or not at which time you can pick the choice you want.
Otherwise keep in mind that what shows on a users desktop/start menu is a
combination of what is seen in the all users profile desktop and start menu
folders [under documents and settings] and the user's desktop and start menu
folder. So you can check both places as an administrator to remove items you
do not want other users to see. Having said that any user may still be able
to run a program if they have at least read/list/execute permissions to the
application folder or executable file. You can modify such NTFS permissions
to remove users and leave only the user/groups you want to have access. See
the first link below on how to change folder/file permissions. You may also
be interested in the free Shared Computer Toolkit that can really lock down
other users and it comes with excellent documentation. The second link
provides information on it. --- Steve
