Mkay so long story short. My computer decided it would be a really good idea to open its big old mouth real wide then just shit all down its own throat recently so I went ahead and ordered parts for a new PC, the usual motherboard, CPU and ram.
So the parts all arrive and I'm thinking to myself ok lets hammer this shit together and see what happens when it dawns on me... It might run better with an operating system =OOO
Thus we arrive at my current predicament. Does anyone have experience who upgraded either their Windows 7/8 OS to Windows 10 via the free upgrade who successfully transferred their licence between machines?
I thoroughly Googled this issue and it turns out that everyone who tried has met one of 2 scenarios, either they installed a fresh OS with no issue or they where met with the old key already used message. Apparently OEM versions are not transferable ever but retail keys are. My original OS was retail 8.1 but it also turns out that some people can do it fine and some cant.
Google has failed me.
