Windows 10: I bought windows 10 through the Microsoft website and I didn't receive a product key

I've bought Windows 10 through the Microsoft website and I didn't get a product key in my confirmation email. My confirmation email was only a receipt of my purchase. I also looked through my order history and there was no product key present. Do I get a refund or is there another way to activate Windows?

my windows 10 oem didn't come with a product key

indeed OEM's have embedded keys a OEM upgrade is for machines with OEM copies and DO NOT COME WITH A KEY! sadly many vendors confuse the two because pre-windows 10 'OEM" came with a key
a end user should always buy a Retail OR "System builder OEM" copy when it comes to windows 10 system builder is not `OEM` you can blame microsoft for the retarded terminology screw up

it sounds like the op bought a pirated copy with no key microsoft does not ship windows 10 on optical disks .... they use flash drives

 

my windows 10 oem didn't come with a product key

Dude, go to Newegg right now and read the questions and answers tab on Windows 10 OEM. The OEM copies that are listed there DO in fact, come on an optical disc. The flash drive ONLY comes on Retail copies.

 

Windows product key

Hi,

I recently bought a new pc with windows 10 preinstalled, outside there is no product key.

Then I did upgrade to Windows 10 PRO and I didn`t receive any product key.

I just want to have it somewhere in case I need to reinstall the system as different times happened with windows 8.

Anyone can help?

thanks

Miriam
