I am still experiencing the lag after the update as well. Alban - Are you then suggesting that the update wasn't included in the September Cumulative Update? I'm sure the reason Mag is asking is because you indicated it would be included in the September Cumulative Update. Are you suggesting that Microsoft will put out another September Cumulative Update?

Like with any KB, you can get what it is supposed to fix from Microsoft website
KB3189866 - Cumulative update for Windows 10 Version 1607: September 13, 2016

The lagging issue is not a security problem.
