Only if you didn't want to.

But 'why' wouldn't anyone want to reserve a 'free' copy of '10 ? what am i missing here ? thanks
What you are 'missing' is that for some folk it just doesn't seem to work. I'm no stranger to installing Windows and occasionally having to jump through a few hoops to get a driver etc for some device or other that is a problem but here, W10 itself won't install correctly, before you even move on to do anything else. My 9yr old Acer on the other hand has run W10 very well once a couple of driver issues were sorted.
Shawn may remember my tale of woe with W10. I have a Dell Vostro laptop and it will not (for whatever reasons) successfully clean install W10 or do an upgrade install of W10. The in place upgrade is unusable with every mouse click taking 10' of seconds to action. The clean install blue screens at the final stages and crashes out.
My master plan was to have put the original Dell OEM W7 version back on the Vostro and updated to W10. I would have then used the W8.1 full license on the Acer and bring that up to W10. But it wasn't to be. And what is more, I really like W8.1
OK, so all that was some weeks ago now, and perhaps the W10 file is updated to include fixes for whatever was stopping it installing. On the other hand, even the Dell website specifically says the Vostro 3750 does not support W10.
