Personally I
far prefer Win7 to Win10, which seems to have been made for kiddies... Stupid nonsense such as 'Cortana' and the obsession with 'Apps' are absent (thankfully) in Win7.
Similarly, I prefer Office 2007 to later versions, particularly Office 365. I've just made a couple of screenshots for a friend - one using Word 2007 and the other using Word 2016. The earlier Word interface was much more professional than the later version...
I also use AutoRoute 2010, but that isn't supported by Win10
. Because the Gates geeks think that everyone is always on-line with some eToy phone and at their mercy with tools such as Google Maps....
