I had "Windows 7 64bit Home (OEM)" installed on this system and purchased a standalone retail "Windows 7 64bit Professional" version in order to upgrade to Professional before I make the jump to Windows 10. I used "Anytime Upgrade" to input the new key and upgrade my Home version to Professional. After successfully completing the process I noticed "System" is still displaying an OEM Product ID although I purposely purchased a non OEM license, since sooner or later my mobo will need to be replaced and I do not want to have to purchase another license just because of this fact. My question is as follows:

If I were to upgrade to Windows 10 now with "System" displaying the OEM Product ID will it give me a Windows 10 OEM or RTM key?

Will using the "Change product key" option under "System" make a difference?

Or do I need to clean install Windows 7 Professional 64bit to make sure the retail key is used to upgrade me to a Windows 10 Professional Retail key?

  • What ever license type you have when you upgrade to Window 10, you get that same type of rights to Windows 10. Since the upgrade does not give you a unique key these rights are entirely digital. Unless you go out and purchase a Windows 10 license, you won't get an actual, Windows 10 retail key. – Ramhound Sep 4 '15 at 12:15
  • This isn't a proper answer to my question I am fully aware of this fact. However; the key I input is a full version standalone retail key for Windows 7 Professional, yet it is still displaying a OEM Product ID. And I want to make sure I get the RTM license rights that aren't tied to my current hardware. – Anon Sep 4 '15 at 12:23
  • What is displaying your OEM product id exactly? You asked the question "will it give me a Windows 10 OEM or RTM key?" and the answer to that question is, you don't receive a unique Windows 10 key, when you accept the free upgrade. What you receive is a generic key, and your transfer rights depend on the key. So if you have Windows 7 Professional, with a retail key, you have transfer rights just like you have transfer rights on the Winnows 7 installation.. – Ramhound Sep 4 '15 at 12:28
  • All the information is already given in my original post. Under "System" => "Windows Activation" it lists a OEM Product ID – Anon Sep 4 '15 at 12:31
  • Honestly. Your question is very hard to follow. I suggest you use the slmgr.vbs -ipk(insert your product key here) at a command prompt. – Ramhound Sep 4 '15 at 12:34
