yeah hopefully that should do it but apprantly you can still install some things, it's just annoying when you get back to find 1000 bits of spyware some weather display and a dancing girl on your desktop and not to mention BONZA BUDDY!!! that thing needs to be shot
True... if you remove the users account from the Admin group, installations become harder. However as long as the installing program doesn't access the registry (most do) the user can still install the program. Have you tried giving that particular user READ ONLY rights to the Program Files directory? You will have to have NTFS instead of FAT32.
