Moin, can you, for example, if I have pre-installed Windows 10 on my laptop and get a PC that does not have Windows 10 pre-installed, transfer it from the laptop? But that I have Windows 10 on both devices… Or is there another option?
OEM is registered once in the system
Has nothing to do with it.
Then correct me
Actually yes, connect once with a microsoft account and then change hardware, your old install will then be deactivated again.
So you can operate both devices with Windows 10? So at the same time you can't leave your laptop?
Each license key can be activated on 1 device. So either laptop or PC. Since this is activated via the Internet, the MS also recognizes that you are trying it on 2 devices.
It is illegal if you operate two PCs at the same time with one key, can easily be determined by Microsoft and then become very expensive…
