Yes, that was what MS planned, to stop offering a free upgrade at some point, but the adoption of Win 10 was so poor (less than 40% of Win 7/8 users), that as of the last time I checked ( a few months ago), you can still install it for free...if you feel brave enough to risk it. So many of the Win 10 updates have caused havoc that I reverted to Win 7 some time ago. If you have had a good experience with Win 10, more power to you. Many people did not. Just check the blogs, tech sites, etc.
