Do you use Dell Technical Updates subscription and/or Dell Update and/or Dell SupportAssist?

Hi all,

I'm interested in your strategies for getting updates for your Dell laptops.

When I got my XPS 15, I subscribed to the Technical Updates service, to receive emails about updates.

That was before I realised my laptop came with the Dell Update application, which advises me of updates via notifications.

I was a bit uncomfortable having two sources of updates. Am I wasting bandwidth downloading the same update twice? Am I overwriting a newer update from one source with an older update from the other source? etc

And I've recently had the SupportAssist 'plugin' installed. Lo and behold, it's Drivers and Downloads section is also suggesting updates.

Do I need all three of these?

I'm tempted to unsubscribe from the emails, uninstall SupportAssist, and just rely on Dell Update. Am I going to miss any important updates if I do this?

Thanks for your help.
