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.
- Expensive
 
Upgrade version (Retail):
- Includes transfer rights to another computer.
- require a previous qualifying version of Windows.
- Expensive, but cheaper than full version
 
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.
