What is the file location of applicationhost.config in the different versions of IIS?

iis, iis-10, iis-7, iis-8, iis-express

Solution

For the "big" IIS versions since IIS 7, the location is always the same:

 %windir%\System32\inetsrv\config\applicationHost.config

For IIS Express there is one per user, the default location is:

%USERPROFILE%\Documents\IISExpress\config\applicationhost.config

again it's the same for all versions.

You can run multiple instances of IIS Express per user, you would need to specify the location of the `applicationhost.config` as the command line parameter `/config` for `iisexpress.exe`
