It is for Kaby Lake
I know it's a bit of a necro-quote here, but...I'm not sure if this was out of sarcasm of not, but if the former is true, surprisingly, you were quite on point:
This must come from a recent update, something around mid/end of March, because I've first seen it on a machine I built for a customer around a month ago, an i3-7100 using his pre-owned Win 7 license...all smooth for almost a month, last week he brought back the machine because of an "error" message that started to pop up everytime all of a sudden...the lenght they'll go to try and make you switch over to 10

...
Truth be told, I find it not even half as bad as it's pictured by some people, I'm honestly not even bothered too much by privacy concerns (1- they're able to know everything about me anyway if they want and 2- let they know everything, they'll be surprised by how much am I a boring person [smile]), all things considered is quite a good OS, stable enough and with good general performances or at least no worse than Windows 7, and that was pretty good already. Also, is a lot more friendly on the drivers side, from my working point of view it takes considerably less time to set up a machine with 10 compared to the previous 7 (8? Never heard of this, sorry), mostly because it does most of the driver updating work on its own compared to previous versions.
Problems starts when there are actually problems. Recovering those things is a pain most of the time, windows 10 try to be "user friendly" and automate everything, and this is a thing I mostly hate, I still largely prefer the good old Windows 7 recovery tools and safe mode in this regard.
I'd still say that, if you really aren't forced or feel the urge to have Windows 10, you'll still be good to go with Windows 7 for quite some time (just, don't apply the recent updates

).
