I upgraded one last laptop in our home running Windows 7 Home Premium to Windows 10 Home for free last week. Windows 10 has come of age in these years and gives much better experience than when it were launched.
It's noteworthy that users in older configuration may face some performance issues. In my case that Age old HP Pavilion dv4-2113tu has only 2GB RAM, and I had to install CleanMem Pro to somewhat normalize the situation. I Plan to upgrade the RAM in future.
