One shouldn't be forced into Windows 10 until they are ready. I don't have any issues with Windows 7 Pro, and what Windows 10 provides isn't needed right now. We only upgraded to Windows 7 once Windows XP was no longer being supported with updates from Microsoft.
Unless one of us starts using Windows 10 at work or Microsoft stops supporting Windows 7 with updates, there isn't a need to upgrade to Windows 10.
As long as your running a retail copy of the OS. If it's an OEM version, it's only good for as long as you can keep the hardware running.
