It took almost 2 years for Windows 7 to get it's only SP. I don't recall any reason not to jump on windows 7 on release. And while I skipped windows 8 because I hated the UI, I downloaded Windows 10 on day 1 and so far it's worked they way I expect it to.
I thought this "rule" was for their server products.
Win 7 was the first Windows version since Win NT 4.0 that I felt a confidence in out of the box.
This was because Win NT4.0 had the development of the Win NT 3.x (there were no versions of Win NT below 3) and the main difference between Win NT 3.51 and Win NT 4 was that the graphics driver had been moved to Ring 0 (Kernel mode) as opposed to Ring 3 (Application mode).
Win 7 was what Vista would have been if Intel had not discontinued their Itanium 64-bit line in favour of going more in line with what AMD was doing with their 64-bit processors.
So all of a sudden Microsoft had to make what they thought would be an extension to their 64-bit OS (and I was a long term alpha and beta tester of Longhorn) into the mainstream 32-bit product (which was thought of as a compatibility mode) because Intel had no 64-bit mainstream CPU.
Win 10 is because Win 8 is, was, and will be a

Really you want to make a tablet based single tasking, touch based, GUI the model for a truly multitasking desktop environment?
Which moron at Microsoft (oh excuse me Ballmer was in charge so I can understand because the lunatic was running the asylum) thought that this would be a good idea really should be certified.
If you look back at my posting history (not necessarily here) I said that Win 8, well before it came out, was not just a disaster on par with Vista, but rather it would be a disaster far exceeding Vista.
Two two word phrases doomed the concept of Win 8 on the desktop
1) Screen plaque
You might put up with smudges on your tablet display, but on your main desktop you are going to get incredibly sick of wiping it off from finger smudges every ten minutes or so.
It's why touchscreens on a larger scale just don't sell, which leads me on to the next reason.
2) Gorilla arms.
People just don't want to use their computers as if they were Dumbledore in mortal combat with Voldemort waving their hands across the screen.
a) Human arms are not long enough to reach a comfortably readable 27 inch monitor
b) Human arms get really tired of moving many inches when a mouse can move the cursor a lot further in millimetres.
The whole concept was
expletive deleted from the outset.
