Thank you all for confirming that this is NOT the time to change from Windows 7 to Windows 10 - or from 8.1, for that matter.
M$ seem intent on self-destruction. Useful programs such as AutoRoute have been discontinued, as was the user-friendly Outlook Express. In came junk like Windows Live and various subscription programs.... They also canned the simple yet powerful Photoeditor. Windows 8 was a disaster, Windows 8.1 was at least less awful. And as for Office 2013.....
As for the creepiness of that latest TV ad, which is almost Orwellian in nature, with M$ seeming to want to control the minds of children....
