I've recently acquired a laptop which had Windows 10 Home installed on it. After doing a lot of research on how to de-bloat and reduce spying/telemetry, I've come to the realization that I need to upgrade to Pro to get more control of my machine,
I've seen some articles/web pages which state I can upgrade for free provided I have an old key for pro/ultimate etc. My desktop dual boots between Win 7 (Home Premium) and Linux and was wondering can I use that Win 7 key or am I stuck with paying for the upgrade.
Just seeing what my options are.
TIA
