You may have had this happen to you recently, but it was a mistake on Microsoft’s part. See here. You might also want to avoid reading the comments if time is important to you.
I still believe that you should update to Windows 10, assuming that ALL of your computer equipment is Windows 10 friendly. It is easy enough to check. Just go to the computer/printer/scanner manufacturer website and if you see Windows 10 drivers (or in many cases Windows 8 drivers will work too), you are good to go and won’t be left way behind.
