The current antiviruses come with separate tools for the update function. This is because most of the default update tool failed due to compatibility challenges, Windows Defender is one such separate entity. It comes in handy to ensure your installed antivirus contains all the update files for this tool.
The application gives you an option for a schedules update but developers advise you to do it on a daily basis. The main toolkit helps you to keep any threats at bay. In fact, it is an offline version of the kit such that when you do not have any internet connection you can still run the update operation.
With this tool, you can even apply pressure for an update function even to the stubborn connection. The signatures on the registries also help to ensure the signatures on the interface also help in the same.
This is a tool which is a safer option because once you have no protective gear against all these threats then your system is vulnerable and can crash anytime. Being a Windows tool- the main OS, you also have a chance to have minimal compatibility issues since most of the drivers work well with the same application.
