Seems to be related to KB3176936. Several installations are affected by this same update. All instances are missing the IIS features immediately after the update. Going to Programs and Features the option is there, but it has been unchecked during the update. I checked it again, but then I had to recreate everything just like a new install.
(Windows 10 on all instances)

The "good" news is that there seems to be a way to restore the IIS app pools and sites (after re-enabling IIS from "Turn Windows features on or off")
It’s a little tricky and error prone, but it’s better than nothing.
Here is the procedure that worked for me:
C:\Windows.old\WINDOWS\System32\inetsrv\config\applicationHost.config. This is the original IIS data from before the update.C:\Windows\System32\inetsrv\config\applicationHost.config. This is the active IIS data.<applicationPools> and <sites> elements in the active file with those from the originaliisreset from an elevated command prompt

which version of windows are you talking about? 7? 8? 10? Server? we need a bit more detail.. – Richie086 – 2016-09-22T17:15:15.947
This is Windows10 in the three cases with which I'm dealing. – Curt B – 2016-09-22T17:16:36.810
please edit the tags and the question to reflect that. Are you saying that when you go to Programs and Features > Windows Features > the option to install IIS is no longer present? Or are you saying that your existing IIS install is not working? – Richie086 – 2016-09-22T17:19:18.287
screenshots would be handy – Richie086 – 2016-09-22T17:19:44.300
IIS is missing. Going to Programs and Features the option is there, but it has been unchecked during the update. I checked it again, but then I had to recreate everything just like a new install. – Curt B – 2016-09-22T17:23:09.450
Ouch. Have you checked to see if it created a restore point before it installed the update? – Richie086 – 2016-09-22T17:28:33.200
I didn't bother with chasing restore points. The need to function was more urgent. I just recreated the virtual directories and applications. – Curt B – 2016-09-22T18:20:09.570
1Confirm that I have the same on Windows 10 Pro after latest update. IIS has been removed and I have had to re-configure from scratch. Totally not cool. – BinarySolo – 2016-09-28T11:28:59.983
It happened to me also. This is just great, settings, websites, dev certs, custom app pools. – Adrian Iftode – 2017-01-04T20:59:19.053
