Yeah 32bit is an issue. Don't install the Linux Lite OS to the PCs at all. Install Ubuntu server and grml rescue boot and run the LL live ISO. They can make all the changes they want while they use it but none will be saved and they won't be able to install it by accident either. They can save common personal files to a USB.
Otherwise you'll have to modify the user permissions on each PC involving the desktop. I do not recommend using the restore default in alacarte. You might want to look into this, much as I don't totally agree with the criticism:
