How to enable Active Directory Recycle Bin in Windows Server 2016

Who did not accidentally delete an AD object in his career?
Without this feature enabled, you had only a few choices. Either you could restore if you used a backup solution allowing you to restore individual AD objects (many virtualization backup vendors do that nowadays). Or you have had less chance and your AD server wasn’t configured to be backed up and you have to recreate the user and reinstall his profile on his computer.
