richardjmoss: The product page states in 3 different places that it supports Windows 7, 8 or 10, not sure if it has been changed or if you missed it. But it doesn't seem to require Windows 10.
If it wasn't completely obvious (which it was), they changed the info less than 24h from release.
Before then, it was Win10 only.
JasonHall: Although to be fair, with Windows 7 getting close to end of support for updates and very little new hardware having proper drivers under Win 7, you probably should be considering a migration to something newer very soon.
Windows 7 is still supported right now, and new hardware support is irrelevant if you're not currently getting new hardware. When support for Win7 ends, I'll migrate to linux.
