Another issue I forgot to mention. Dell has a limited return policy if you decide you don't like it and want to return it. Its different for UK and EU than it is for US and don't know what that period is. I wouldn't do any upgrades or reconfigurations until the return period has passed.
That will work. It can be tedious and time consuming depending on how much junk is preloaded though. My ASUS was loaded with junk Apps. Stuff gets left behind too, because uninstallers often leave stuff behind. I think the OP is looking a quick way to do it with minimal input from the user. IMHO, a clean install is the way to go. My factory OEM installs on my laptops are long gone. Good riddance. If you use the correct install media the embedded keys get detected automatically. No prompt to select the version and no prompt to enter a key. Activation is automatic too. Just a few options to select and its done with no bloat. Let Windows Update do its thing and all your drivers should be installed in the background for you.
Yup, that's exactly how I did my Dell laptop for clean install. Once updates were done, I looked in Device Manager, sussed out which devices were the unknown ones flagged therein and downloaded those drivers from Dell (did have them saved from original but downloaded to make sure most up-to-date) for install and complete functionality.
I had to hunt a couple of drivers up when I was running Windows 8/8.1. Everything works for me in Windows 10 though. I just have to give it a little time to install them. I'll be tweaking my settings and see my screen flash when the Video drivers are installed. Usually about 10 minutes or less and everything is working.
