Hi Dino,
This is from an older post about the w7-to-w10 upgrade with a link:
Page describing the free Microsoft w7-to-w10 in-place upgrade:

Expect lots of updates and restarts.
Preserves your logons and programs, sometimes complains but updates hardware drivers.
Never hurts to have your original W7 key, either from a sticker or from a key-finding utility.
An image backup from something like the free AOMEI program is also reassuring.
It's worked on a few dozen systems for me, mostly Dells and HP's.
Don't expect the machine to be any faster.
