I don't think that tool asks for a key if you are running the version of Windows you are trying to download the ISO for.

 

Will Windows 8.0 pro upgrade key work?

The answer to that question is yes it will activate Windows 10 Pro. What it won't do, though, is trigger an upgrade from Windows 10 Home to Pro.

1. Install Windows 10 Pro - not activated. Enter Windows 8/8.1 Pro upgrade product key. It will activate.
2. Install Windows 10 Home. Change product key. Here a Windows 8/8.1 Pro upgrade key (and any Windows 7/8/8.1 Pro product key) will be rejected. Instead enter the Windows 10 Pro generic product key and the upgrade to Pro will be triggered. Now you have a non-activated Windows 10 Pro installed. Change product key again, enter the Windows 8/8.1 Pro upgrade product key and it will activate.

Now - this is all assuming that the Windows 8/8.1 Pro upgrade product key has not been blocked from automatic activation. What I don't know is if phone activation will work in that case - or if the user must actually install Windows 8/8.1 Pro and activate it via phone first. My Windows 7 product key (good for 3 license family pack) has been blocked from automatic activation and I have to call the recorded phone line every time.

 

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
