Windows 10: How can i check my Windows 10 License Retail or OEM version.

because my windows 10 is upgraded from a windows 7 disk that I bought like more than 5 years ago, how can I check it?

:)

 

Oem and retail license

Full version (Retail):

- Includes transfer rights to another computer.

- Doesn't require a previous qualifying version of Windows.

- Expensive

OEM :

OEM versions of Windows are identical to Full License Retail versions except for the following:

- OEM versions do not offer any free Microsoft direct support from Microsoft support personnel

- OEM licenses are tied to the very first computer you install and activate it on

- OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard

- OEM versions cannot be used to directly upgrade from an older Windows operating system

What happens if I change my motherboard?

As it pertains to the OEM license this will invalidate the Windows 10 upgrade license because it will no longer have a previous base qualifying license which is required for the free upgrade. You will then have to purchase a full retail Windows 10 license.
If the base qualifying license (Windows 7 or Windows 8.1) was a full retail version, then yes, you can transfer it.

From the Windows 10 end user license agreement:

b. Stand-alone software. If you acquired the software as stand-alone software (and also if you upgraded from software you acquired as stand-alone software), you may transfer the software to another device that belongs to you. You may also transfer the software
to a device owned by someone else if (i) you are the first licensed user of the software and (ii) the new user agrees to the terms of this agreement. You may use the backup copy we allow you to make or the media that the software came on to transfer the software.
Every time you transfer the software to a new device, you must remove the software from the prior device. You may not transfer the software to share licenses between devices.

 

When I upgrade a preinstalled (OEM) or retail version of Windows 7 or Windows 8/8.1 license to Windows 10, does that license remain OEM or become a retail license?

If you upgrade from a OEM or retail version of Windows 7 or Windows 8/8.1 to the free Windows 10 upgrade this summer, the license is consumed into it. Because the free upgrade is derived from the base qualifying license, Windows 10 will carry that licensing
too.

If you upgrade from a retail version, it carries the rights of a retail version.

If you upgrade from a OEM version, it carries the rights of a OEM version.

Full version (Retail):

- Includes transfer rights to another computer.

- Doesn't require a previous qualifying version of Windows.

15. UPGRADES. To use upgrade software, you must first be licensed for the software that is eligible for the upgrade. Upon upgrade, this agreement takes the place of the agreement for the software you upgraded from. After you upgrade, you may no longer use
the software you upgraded from

"If you upgrade from a retail version, it carries the rights of a retail version." - source?

I contacted MS support but they didn't know and redirected me to tech support which's answer wasn't really clear either.

I have found no official information for your claim at all.
