From the Microsoft Inside Out XP book we find the following:
Making a Program Available to All Users
Most of the time, when you install a Windows program from an administrator's account, its shortcuts are placed in %AllUsersProfile%\Start Menu\Programs, so that any user who wants to run that program can do so. Exceptionally well-written programs ask you whether you want to install the program for all users or only for the currently logged-on user. (This option is especially appropriate when you're installing a utility program that you don't want other users to be able to run.)
What should you do when Setup installs a program only for the currently logged-on user? If you want other users to have access to the program, you have two choices:
Log on using each user account and rerun Setup. This option gives you the flexibility to make a program available to selected users, but it has one significant drawback: you have to remember to run that Setup program again every time you create a new user account.
For simple programs that don't require per-user settings to be added to the registry before running, you might be able to simply add a shortcut to %AllUsersProfile%\Start Menu\Programs. To ensure that a program is available to all current and future users, move the program's shortcut from your personal profile to the All Users folder.
To move the program's shortcut, follow these steps:
Click the Start button, right-click the shortcut or group you want to move, and then choose Cut from the shortcut menu.
Right-click the Start menu and then choose Explore All Users.
Select the Programs folder, right-click, and then choose Paste.
Use the same basic procedure, only in reverse, if you want to move a program shortcut or group from the All Users folder to your personal profile so that it is no longer available to other users. They will still be able to launch the program from the Run box or from an Explorer window, but you will have removed the most visible means of access to the program.
The Inside Out XP book is a wonderful reference and very well written. You can find it any most respectable computer stores, or order it directly from Microsoft. Easily worth the money. Another excellent source for information is the Microsoft Support center for XP. Lots of information on the basics and beyond for users of all levels.
