Hi all, I want to create a password so that I can block other users from making changes to my computer (e.g. prevent the deletion of programmes by ensuring that anyone wishing to do this has to type a password prior to being able to do so). At present my PC has only one password which everyone in the family uses to log in. How can I allow others to access the machine while, at the same time preventing the changing and/or deletion of programmes? On going into control Panel it appears that I have administrative priveleges, however I don’t know how to use them to do as set out above. Any assistance gratefully received. Thanks, Kevin
