When trying to install Windows Defender i get an error message that "Service 'Windows Defender' (WINDEFEND) failed to start. Verify that you have sufficient priviledges to start system services"How do I check what priviledges I have and I need?I noticed in task management that Norton's symlcsvc.exe was running and I wondered if this was clashing with Defender so I temporarily stopped Symantec process running in the Services area but still had same result trying to run the Defender's installation.Help please1 person needs an answerI do too
