Not a fraud. That's the license agreement that was agreed to upon purchase and use.
A laptop generally comes with an OEM license. Meaning you buy the license from the manufacturer (Dell/HP/whoever) at a much reduced price. You do not buy it from Microsoft.
In exchange for that much reduced price, you agree to the fact that it is licensed to that original machine.
The OP got 6 years of use out of the original OS. The crappy laptop died, along with that OS.
Now....what could have happened is that the OP created a recovery disk set, and when that laptop died, bought another, equally crappy laptop and maybe/probably used that original disk set to reconstitute it on the new crappy laptop.
Moving a laptop drive and OS to a new shiny desktop is 2 levels of weirdness.
1. Does it even boot? Usually not. The hardware is too different.
2. Licensing. That OEM is licensed to that original machine.
