I have installed CCleaner initially via my administrator account on this laptop computer- Windows 7. I recently created a standard user account on this same computer and is NOT password protected. The administrator account is password protected. I regularly logon & use the standard account. The CCleaner app "works" without asking me for the administrator account password. My question is how could I prevent CCleaner from coming up without some form of security while logged into the standard account? It seems to me that I could make changes to the security permissions in CCleaner properties. I would appreciate any help or comments.
