I do care, (and of course we still support IE11 on any OS version) but Win7/IE11 users are gradually upgrading on their own. I was afraid that IE11 would literally never go away. Microsoft has said that they'll support IE11 until Windows 10 reached End of Life. But they've also said that Windows 10 is the "last version" of Windows, that they'll continue shipping new updates for Windows 10 in perpetuity. Now, I have hope.
