Took 30 seconds to pay and activate. 10/10

Hello,
I would like to ask you if my purchases are legal for audit from Microsoft in Business Environment.
I think without sticker and invoice of Windows 10 are not legal.

Clé windows 10 recue, fonctionne parfaitement, merci

Real W10 retail key, not OEM!
Took 1 star off because order was delayed and needed to email support as order was in "pending" status. (not instant delivery)
