When you try to install Windows Defender I get an error message "Service"Windows Defender"(WINDEFEND) could start. Make sure you have sufficient privileges to start system services.

Original title: could not start the Service "Windows Defender" (WINDEFEND)

When you try to install Windows Defender, I get an error message that

"Service"Windows Defender"(WINDEFEND) was able to start. Make sure you have sufficient privileges to start system services.

How can I check which privileges I have and I need?

I noticed in the management of the tasks that Norton symlcsvc.exe ran and I was wondering if it was who collide with the Defender, so I temporarily stopped Symantec process running in the field of Services, but still had the same result, try to run the installation of the Defender.

Help please
