I recently did a system cleanse using my anti virus software. i used it primarily to remove unneeded start up programs. in starting it up, my start menu has lost all programs, including folders like Accessories and Paint, Calculator, also my desktop was removed of all Shortcuts. to open a program i have to go to c://Program files/ program . etc I now cannot reset the start menu Properties as i get a message saying the "this operation was cancelled due to restrictions in effect on this computer. I only have one user, and my user is administrator. How do i find this restriction and why did i lose all the items. Is this mor edue to my Security Settings or my Anti Virus software. Software, iolo System Mechanic.
