Windows 10 Creators Update之后IIS消失了（包括站点和应用程序池）

Question

After installing the Windows 10 Creators Update (1607), IIS is no longer installed.

When I re-install it from "Turn Windows features on or off", I find that all my application pools and all my sites are gone.

Answer 1

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:

1. In a text editor, open C:\\Windows.old\\WINDOWS\\System32\\inetsrv\\config\\applicationHost.config . This is the original IIS data from before the update.
2. In another text editor open C:\\Windows\\System32\\inetsrv\\config\\applicationHost.config . This is the active IIS data.
3. Replace the <applicationPools> and <sites> elements in the active file with those from the original
4. Run iisreset from an elevated command prompt
