Trying to upgrade to windows 10 from windows 7 licensed from a windows 10 downgrade

[Mark8080]

I have a laptop that originally came with a windows 10pro operating system. We had to roll it back last year to windows 7pro because of a software incompatibility issue. That issue has been resolved. I tried to download windows 10 from Microsoft, but it reported that there was no valid windows 10 license was available.

Unfortunately, it isn't a clean story, as the laptop downgrade process totally failed (HP red screen of death, anyone?) and it was sent into HP which returned a Windows 7 laptop. I didn't track the license. So it could easily not be the one originally supplied with the laptop.

Is there are more HP way to upgrade this laptop back Windows 10, or is the Microsoft path the correct path and that this laptop's licensing is not recoverable?

Thanks.

Hi,

Please check the link below to download windows 10 pro OS :

Note :

You need to have flash drive not less than 16 GB.

before running the Cloud recovery app-connect the Flash drive.

follow the instructions after running Cloud recovery.

You will not get any prompt to activate windows since its OEM image from HP.

This is exactly what I was looking for; however, once I looked at this I abandoned plan A. I ended up going to plan B. I had made an image of the Windows 10 system prior to downgrading via the Red-Screen-Of-Death to Windows 7. I used this image and then Windows 10 update do the rest. So if I didn't have plan B, I would have tried plan A.

Thanks.
