Ladies annmedia:
Quote: 4. Transfer. The provisions of this section do not apply if you acquired the software in Germany or other countries listed on this page (aka.ms/transfer), in which case all transfers of the software to third parties and the right to use it must comply with applicable law.
a. Software pre-installed on the device. If you acquired the software preinstalled on a device (or if you upgraded from the software preinstalled on the device), you may transfer the license to use that software directly to another user as long as you simultaneously transfer the licensed device to that user. This must include the transfer of the software, if one came with the device, as well as the original Windows product key label. Before receiving the software, that user must agree that the terms of this agreement apply to assigning and using the software to another user.
b. Standalone Software. If Licensee acquired the software as standalone software (or if Licensee upgraded from software acquired as standalone software), Licensee may transfer the software to another Licensee's device. You may also transfer the software (with the license) to another device owned by someone other than you, provided that (i) you are the first licensed user of the software and (ii) the new user accepts the terms of this agreement. You may use a backup copy or genuine software media as permitted by Microsoft to transfer the software. Any time the software is transferred to a new device, you must remove the software from the previous device. The licensee may not transfer the software so that licenses can be shared between devices.

then please indicate which version the above fragment comes from and present a quote from "the second". A quote documenting the difference the Lord wrote about.
Just please do not rush to reach for licenses other than for Windows 10 - this thread is about this system.
Lest it was that a system installed "loosely" can always be moved - there is one and this is an undocumented exception. It applies to licenses obtained as a thank you for participating in the Insider program before the premiere of Windows 10. In this case, not only the license cannot be transferred, but even minor hardware changes can cause - and often cause - the loss of activation.
Point 4 of the license terms as quoted above have been in force for well over 4 years (for about a year after the premiere of Windows 10, they looked different, but this is a completely different story. A story that only those who not only have a good memory, but also have the habit of knowing "what's going on in the license".
PS
I would also be careful with OEM, as in the case of Windows 8, for example, there were two license versions. The differences between them can be easily checked today - the texts are available
