I have a feeling that's going to happen at some point. According to NetMarketShare's Feb 2016 data Windows 7 still owns more than 50% of the market despite Windows 10 being available for free since July 29, 2015. Based on those numbers you'd think at some point Microsoft would have to admit that they're Microsoft Knows BestTM strategy just isn't working. I don't know about anybody else, but it feels like we've been waiting since October 2012 for Microsoft to be like "It's just a prank bro. You thought we were serious?" and release a real successor to Windows 7. Microsoft has said they never want to go through XP-style holdout again, but I don't think they have a choice. The data suggests that Windows 7 will likely become go through a similar holdout. Plus, the sheer aggressiveness with which they are pushing Windows 10 isn't doing them any favours. July 29, 2016, will decide Windows 10's fate IMO. Fortunately, if this is how well it does when it's free it should only do worse because there will eventually be a barrier to entry that wasn't there initially.
