Need to confirm how many systems that you can install one Win 10 licence,

[adam1user]

I was talking to one person who is good in computers (software and hardware), he studied computers. He informed that you can install Win 10 on 5 computers using the same activation code. Is this correct? I mean he referred to home version (which is the one licence) and not the company licence where you can specify several users or several computers and pay for them too.
Can someone shed some light on this. thanks,

One license...... One computer.
Pretty simple. Regardless if you are upgrading a previous version of Windows to Windows 10, wherein the previous license (product key) supports the upgrade or ....
IF you purchase a Retail or OEM license with an associated product key..... It's still one key one computer (system).
Excluding of course Volume Licensing for enterprise customers, which is still basically the same thing you just purchase the rights in groups by volume and your installations can not exceed your volume license.
