Question

Windows 10 upgrade activation fail?

So, the idiot I had repair my Dell laptop computer wiped the hard drive and installed Windows 8.1 Professional, even though the COA in the BIOS is for Windows 8 Home.

Not unsurprisingly, Windows 8.1 Professional won't activate. And, it seems that the only way to get Windows 8.1 Home back on the computer is to re-install Windows - something I'd really, really rather not do. I have a Dell disk to do it with if I absolutely have to, but it's a last resort.

I was hoping that installing Windows 10 would save me - since I do have a legitimate Windows 8 COA. No such luck - the upgraded Windows 10 won't activate with the Windows 8 code I pulled from the BIOS. So, I reverted back to 8.1 for the time being.

Is there a way out of this short of installing a clean version of Windows 10? Re-installing all of my programs and losing my stored passwords, etc. would be such a major pain in the butt - I'd like to avoid that if at all possible.

You won't like it.

You could buy a license to 10 and use that to activate it. All your past licenses are based on an OEM (Dell) OS and the keys for those do not apply to Retail or what they used.

not much you can do without legit install

you either need to go back to the repair shop and get a legit license for the install or reinstall everything. If the repair shop does not make things right, you can always report them for piracy.

Well I would talk to Dell

if they installed a Windows that won't activate. Typically when an OEM installs an OS they activate it.
