Can I upgrade to Windows 10 on two computers with the same Windows 7 key?

[feriner]

My plan was to install the Windows 7 on one computer, upgrade to Windows 10 for free, then reactivate Windows 7 on another computer, and upgrade that to Windows 10.

I've done this upgrade switcheroo business with Windows 8 upgrade key before and I was wondering if it would work the same way now that the Windows 10 upgrade is free.

Thanks!

when you upgrade to windows 10 they take that key and register it to a digital windows 10 key. the keys will be locked to the hardward of the pc. so the second upgrade wont work.
