The Register has jumped on the bandwagon as far as it goes for the "features" regarding User accounts not allowing programs to run, or Users having the ability to add Administrator accounts without passwords(?) LOL! Well they logged into the Windows XP support groups and encountered the word Administrator 200x to try and get the low-down with just what the problem seems to be with XP and un/limited users running various programs. Heres a blurb:
According to the relevant Microsoft support article, the problem occurs "because many programs were written for use with Microsoft Windows 95, Microsoft Windows 98, Microsoft Windows 98 Second Edition, or Microsoft Windows Millennium Edition (Me). These operating systems did not have an administrator or limited user account."
The way installations should work with XP, if we understand the situation correctly, is that when installing under administrator account you should be able to specify that other accounts have access to the program, but clearly that doesn"t always happen with the older stuff.
