One doesn't 'share' applications. They are all installed, however an administrator account can be used in such a way as to prevent access.
In future install all applications as User [if the user is not an administrator - change them to one].
Try a simple proceedure to add the application shortcut to the start menu, if changing User to administrator priveledges doesn't automatically bring them up.
Right click on 'Start' button
Click on Explore
Expand the folder 'Programs' under the 'Start Menu' folder
Here you will see all the Shortcuts
You can Login as administrator and see all the applications, copy all the shortcuts to a shared folder.
Then login as User, copy all the 'misssing' shortcuts from the shared folder to Start Menu. Delete the unused items from the shared folder.
