1. Moving a laptop OEM Windows install to a new PC will not work. That installation is tied to the original motherboard. So you need to buy a new OS for the new PC.
2. Even if the licensing worked, there is far too much difference between the original laptop and the
new' PC for it to actually run.
3. Even if 1 or 2 were irrelevant, now you have a laptop with no OS. Someone has to buy a new OS.
