Windows 10 Windows 10 to Windows 7 with HD swap on new laptop?

[InitialKev]

If I have a laptop that is Windows 10 and swap out the HD with my current solid state HD that has Windows 7, will it work and everything be the same as my current laptop? A friend of mine says I might have driver conflicts or it might work without a problem.

It might work with the odd blue screen or two but it also depends on the Windows 7 licence. If it's a retail copy then fine you will, if the os works at all, have to activate Windows again as it's a different machine. If it's an OEM copy then the licence is tied to the machine it was installed on and is non transferable.

It should be an OEM copy as it came installed when I bought the computer. I had to upgrade to a SSD about a year ago when the original HD failed.

Sometimes Microsoft will issue a new key if say the motherboard had died. When installing a new motherboard the os will see it as a new computer which breaks the licence on OEM's. One can phone Microsoft regarding the activation and sometimes they'll give you a new key especially if the old machine died, wink, wink.

1. Select the Start button Link Removed, right-click Computer, select Properties, and then select Activate Windows now.
