I run windows 10 with no issues.
Funny how people claim to run Win 10 without issues then explain they needed the pro/enterprise version and how and what they disabled and turned off and it is still a privacy leak and of course no one knows what the next update which most people can't refuse will bring.
There is a reason why almost twice as many people are still running Win 7 compared with Win 10 despite Win 10 being free and rammed down their throats by Microsoft. Sadly if enough sheeple accept the polished turds Microsoft produce that is what all of us are going to get, but, hey I'm glad you have no issues, apart from the ones you had, and have, and that updates will bring.
On Ryzen Win 7 support opinion is divided. AMD said they would and then said they wouldn't and yes some Ryzen hardware seems to list Win7 drivers.
I run Windows 10 home on a windows 7 era laptop with no issues as well (the laptop didn't even have windows 8 support). So you certainly don't "need" nor did I say you "need" the pro or enterprise version. I simply stated I run windows 10 with no issues though I use Win 10 Pro and disabled the bloat and dodgy stuff.
My PC ran perfectly fine with the bloat and dodgy privacy stuff , but anyone who knows anything at all about IT security immediately disables all the key-loggers and other things baked into Win 10, or at least I would hope they do.
I find it particularly amusing when people freak out about windows privacy issues and then immediately go on facebook/social media on their phone... Never realizing or caring that all of the things they are scared about windows 10 are already baked into Android, IOS and the majority of social media apps.
Windows 10 has 25.6% of the market share now, so it has already done far better than windows 8 or 8.1 combined. While there are people who prefer windows 7 still, that market shrinks each month especially in the enthusiast and business markets.
It is important to note however that windows 10 falls in a period where most enterprise and business customers are looking to migrate to a newer version of Windows due to 7's extended support cutoff in 2020. Windows 8 and 8.1 both fell outside of this upgrade period so most enterprise/business customers ignored them.
I happily acknowledge that there are issues with windows 10, but it is far from the fiasco that was Windows 8. There seems to be some sort of rose coloured glasses issue going on where people remember Windows 7 as being perfect and having no privacy/security/usability issues... and yet at launch out the majority refused to upgrade from XP and many had the exact same issues that people have with windows 10. Fact is no matter how good an OS is at launch it will never be as stable and secure as the OS that has been patched for the last 5-10 years, change is always difficult.
Microsoft is actually fairly open about what their updates will bring, it is easy enough to find the patch notes if you actually care.
The biggest pet peeve I have, is the automatic install of all service packs and driver updates. In my opinion it is far from a "Polished Turd" but it all depends on how open to adaptation you are. The fact remains, this is the direction Windows is headed, and while it may not be ideal, it is certainly better than Windows 8 and 8.1 which both failed horrendously due to innumerable compatibility issues that still plague the OS.
As for the Ryzen support, it is listed on the official AMD drivers page as supporting Windows 7, so it is supported. Whether Motherboard and device manufacturers wish to use engineering time developing for Win 7 which is E.O.L.(End Of Life) and has already been dropped from Mainstream support and will be dropping extended support in 2020, well that is a completely different issue.
Anyways back on topic,
I am excited to see what Ryzen 5 and Ryzen 3 will bring to the table. If they can manage the same single threaded performance as Ryzen 7 but in cheaper more mainstream machines, it could become a decent rival to the I5s and I3s.
