Re: Dell System Detect - Do you need this to check for driver updates
I don't think so. I suspect it checks against Microsoft's own lists. DELL often uses modified drivers so you need to check on the DELL website for the latest drivers.
I do this for most of my drivers. Log in to the DELL drivers and downloads using your TAG and check the dates of drivers against the ones you already have installed.
There are some exceptions.
I never use the DELL NVidia Graphics card drivers as they are mostly (always) out of date. I load the latest direct from the Nvidia website.
Contrariwise,continued Tweedledee, if it was so, it might be; and if it were so, it would be: but as it isn't, it ain't. That's logic.
