I have hp omni 10 tablet which came with windows 8.1. I want to clean install windows 10 and want it activated with windows 8.1 license.
I followed this article http://www.howtogeek.com/224342/how-to-clean-install-windows-10/
According to that article i have to first use Microsoft upgrade offer which i did and make sure my windows 10 is activated and it will store my hardware information for activation next time. Then i have to make sure my system is uefi mode and clean install windows without key.. then Microsoft will automatically activate my windows 10 with hardware.
I followed all the steps but my windows is not activated.
It doesn't activate on activating and when i force to activate it with slmgr.vbs /ato it says product key has been blocked
I have not inserted any product key and the product key that is installed it is not my windows 8.1 product key.

You have to contact Microsoft.
I know because the same thing happened to me. If you provide them with your previous product key they can generate you a new one.
Best phone number to call is the one when you attempt phone activation,
however since you're already connected to the internet I don't know if you can bring that option back upSimply explain your situation and you'll most likely be transferred to an escalated department. Make sure you get the agents name and a case number.
