Trouble is, giving users Limited (MS's bullshit name for accounts in the "Users" group) rights also screws over a lot of other programs. They may have fixed it in later versions but back when I ran 2000 Pro I had lots of trouble getting stuff like Acrobat Reader and Paint Shop Pro to properly register themselves under different user accounts until they were given at least Power User (a group which MS's bullshit "Add User" wizard doesn't even let you assign. This is why I do all my account manipulation in the Computer Management console under both 2000 Pro and XP Pro) priveliges.
