Hi, Jan, I understood exactly what you meant, don't worry I tried something different, just because I had Windows 10 installtion on my pendrive (from some installation at work). I launched the installation from USB and my Win7ProOEM Dell key was accepted right away. I think this is because I already converted 1 year ago a Windows 7 pro to version 10 on the same computer, from the same key. Microsoft kept my certificate on its servers and now when I entered the key again, it found the valid Win10 Pro certificate. The computer was indeed hard wired to internet at installation. So it's not exactly what I'd call a solution to my initial problem, but I have what I needed, so it's OK. Thank you again!

This is great to get such a quality help from a forum. Thank you. I am going to try it and will come back with the results.

Hi Thank you for your detailed and quick answer. I'm afraid my key is not working with Windows 7 Pro Retail. It's not geographically locked, it's a DELL OEM key. By phone, Microsoft told me that my key is OEM and my product is not OEM so they cannot activate it... Do you mean I can send you my DELL OEM key by message and you will be able to add the download to the database of Windows Iso Downloader? That would be fantastic! Best regards,

Hi, Using this great tool for years. Today I have to install a Windows with a "Windows 7 Professional OEM" key. The problem is I cannot find any Win7Pro in OEM. And I remember from the past that it won't work with non-OEM. But I already had this ISO in the past, I'm sure, because I already used this key on the same computer. Where can I download the ISO for Windows 7 Professionnal OEM, please ? Thank you!
