hi i have a pavilion 15 it came with windows 7, but got a free update, 10 years down the line to today ive had to take to a store for factory reboot, 

but now its telling me the windows 10 which was installed in my laptop at the repair shop is saying not activated, i thought i had done a full back up on an external hard drive but even that doesnt work, i need to use this hp pavilion for my itunes. so i bought a new laptop, but when i sign into the old hp pavilion laptop it is showing me settings for my new asus vivabook

I'm having problems following the scenario ...

OK, so you upgraded this Win7 PC to Win10 and all was OK for ten years, right?

But then, you took the laptop to a repair shop and NOW, the same laptop is saying it's not activated.

Clearly, the repair shop installed an invalid version of Windows on the laptop -- and we can do nothing about this.  You have to deal with the repair shop on this.

Don't know how you did the full backup, but my own experience is that built-in solutions and Microsoft solutions are unreliable.  So, I can't help you with either of those.

You probably have account information synched through Windows and that can cause havoc with Windows 10 PCs that use MSN logins -- which is why ALL of my PCs use only local logins.  To change the login on your old laptop to a local one, read this information:  https://www.tenforums.com/tutorials/5374-switch-local-account-windows-10-a.html
