[H] Installer on startup

[joeuser]

Got a Win2K machine in the shop here. Every time it starts up it tries 
to install some apps. Since the media for the apps is not present it 
will not install and take multiple cancels attempts before it goes away. 
Searched the registry and the autoexec and stuff and still I cannot find 
where these apps are being called from. Any ideas? I would install the 
apps just to make it go away, but the customer doesn't know what they 
are or how they got on in the first place.
