|We, the office, will start upgrading our computers OS to Windows 10.
We are not certain if doing an upgrade is enough or if we need to do a full re-install in regards to our current windows licenses ?
If I do a simple in-place upgrade my machine, I assume that Windows 10 will check that i have a proper license (product key) when it activates itself.
If I want to do a full re-install (reformat and reinstall everything), I assume I will need to have my Windows 7 product key and enter it at some point ?
I'd rather be phishing!
