Every time I purchase a Dell system (I have had more than a few) I always format the drive and clean install Windows 10. You may already know but you can download the media creation tool from MS here.
I assume I can download all needed drivers and apps from the R10 support page?  I want to pick and choose what s/w is installed on the desktop after the clean installation of W10.  I also plan to upgrade to W10 Pro at the same time.  Thanks for any input or prior experience with this request.  
Can I replace the Dell installation of W10 on my new R10 with a fresh 
installation of W10 I own?
