Windows 10: windows 10 10074 product key

Hello everyone,
I downloaded the iso-Windows10_InsiderPreview_x32_IT IT_10074 but when I try to enter the product key is written to me: I could not test the product key, and checks the destination media.

thanks

Windows 10 Activation - after clean install from Tech preview build 10074

I was part of the windows Insider program. I had installed Windows 10 Tech preview on my Dell XPS laptop that had previously had Windows 8.1 installed on it. The product key for the windows 8 installation was part of the UEFI settings (ie installed on
the motherboard).

I had the Windows Tech preview build 10074 installed on my PC. For some reason it was corrupted and was not able to be upgraded past build 10074. I attempted to roll back to Windows 8 but had no success as I did not have the correct install media and the rollback
option was not working.

I ended up installing a fresh version of Windows 10, it seemed like my only option to get past the preview build 10074. Now I am being prompted for a product key for Windows 10 even though it should be a free upgrade from Windows 8.1. Given the tech preview
build 10074 did not let me use the normal upgrade path, how do I get my product activated ?

I have contacted 2 different Microsoft Helpdesk staff and they have been of no help. They tell me that I need to purchase a product key. I am only in this position due to the corrupted 10074 build that prevented me form using the normal upgrade path. I am not
so keen on spending $300 on a product key.

 

how Can We Get the Product key of windows 10 if we want clean installation ?

I have upgraded windows 10 build 10074 from windows 8.1, it covered 60 GB space in local disk C and then upgraded windows 10 insider preview 10162 from insider preview build 10074. Now my local disk C occupied 84.6 GB space. I want to make a clean installation
so that the windows occupy only 10 to 15 GB Space. For clean installation i need product key. from where can i get this key ?

 

Is that first TP you are trying and are you true insider and didn't just download that ISO from elsewhere ?
