Question: I would like to be able to lock the desktop.
I am the main user of a certain computer in the office and prefer the taskbar at the top of the screen.
I do not want others to have permissions to move the taskbar or to delete certain folders on the desktop.
Answer: Each user should have a separate login. Each login can be customized separately to set up the desktop the way that the user wants it to look. Unless someone else is using your login instead of their own they should not be able to change your settings.
