I know the March 2016 (KB3139929) update includes the Windows 10 nag, but is the Windows 10 nag still included in the May 2016 (KB3154070) update?
Nag? many said it's just new-tab prompting, but yet never showed for anyone anyway, IE updates are called cumulative for a reason, it contain all previous fixes including such nag
From October 2016 Cumulative Update Internet Explorer 11 for Windows 7 KB3191492 (11.0.36) It is no longer available as a single update, but along with the update of the OS!
MS has changed the way they provide updates now, so IE11 CU's will be in only security monthly rollups. First post updated KB3192391 replaces KB3185319.
