I am currently looking to buy a new laptop on a somewhat tight budget. In order to get a bit better parts I have the option of buying it without a Windows license. I need Windows however and after some thinking I remembered that I have an old PC collecting dust which should have a retail version of Windows 7. Now I've long forgotten where the key is or even if I had a key (it might have been a volume license thing from work) so I have a few questions...
How can I check what type of license I have and whether it can be transferred to a new PC?
If I can use the old license, how can I see the activation key?
I've read that even now (about 2 years later) one can still upgrade to Windows 10 for free? How is the best way to do this? I mean is it better to upgrade on the old PC and then reinstall on the new one, or should I install Win 7 on the new laptop and then upgrade?
I hope I've managed to ask my questions clearly enough as I don't think I understand Microsoft's licensing policy well.
Thank you!

script to find the key in use. it'll also tell you the license type. Additionally, you should be able to upgrade to Windows 10 Pro if your current version is 7 Pro or 7 Ultimate. Enterprise doesn't look like it's eligible for Windows 10 upgrade...
