No, you cannot reuse an old Windows 7 serial key. Each key is unique and must be used once for activation.

Sure! You can use your old Windows 7 serial key on another PC, even if you don’t need it anymore. The license isn’t tied to the device itself—it’s tied to the product activation. Once you’ve activated Windows 7 on one machine, you can usually activate it again on a different one. As for upgrading to Windows 10, yes, you can do that for free after the upgrade completes. Just make sure the system meets the requirements before proceeding.
It's easy to reuse it and handle the upgrade part. Thanks for the help! That really saved me money—better parts too ;-) EDIT: Also, if I don't have any CD or the actual OS, I can download an ISO from Microsoft's website, can I?
You should be able to run the same Windows on both laptops without issues, as long as you install it on the less frequently used one.
It's uncommon but still used. The registration is tied directly to your laptop's hardware. If you register it on another device, it may not function properly or could be considered invalid there. My approach ensures this doesn't occur. If you're open to taking the chance, proceed; otherwise, a fresh install might be safer since it typically uses the same machine.
