startup programs start twice

When a shortcut is placed in Documents and Settings/All Users/Start Menu/Programs /Startup the program starts up twice, or for other programs starts once and a popup says it can't be started twice.

(If the program is placed in Documents and Settings/Administrator/Start Menu/Programs /Startup OR in Documents and Settings/Default User/Start Menu/Programs /Startup nothing happens - programs don't load at all.)

Could someone tell me where in the Registry to go to make a change to stop this from happening? It almost seems there is a duplicate entry somewhere in the registry.

Thanks

Relocating Shell Folders

Certain shell folders-for example, My Network Places and Printers are constructs of Windows 2000 that do not correspond to traditional disk directories. You can display them as folders in Windows Explorer, but you can't display them with a dir command at the command prompt. You also can't change their locations, because they're not located anywhere!

Others, such as your Start Menu folder, are ordinary disk folders. These you can relocate if the need arises. Both you and a colleague, for example, might want to move your Favorites folder to a network share so that you can enjoy each other's latest Web discoveries. Or you might want to move one or more such folders to a different partition if the one where they're currently located is running out of space.

To change the location of a shell folder, you need to edit the registry key HKCU \Software\ Microsoft \Windows\ CurrentVersion\ Explorer\ Shell Folders. To make the change, simply double-click the appropriate value in the right pane of Regedit or Regedt32 and supply the new path and folder name.

After changing HKCU\ Software\ Microsoft\Windows \CurrentVersion\ Explorer \Shell Folders, move on down to HKCU\Software\Microsoft\Windows \Current Version\Explorer\User Shell Folders. If the shell folder you're relocating also appears in this key, make the same change here as well.
