IIS 8.5 not using applicationHost.config?

Question

Using Windows server 2012 R2 with IIS 8.5.9600.16384 I wanted to change some config options for the IIS because i have a slow first load issue.

All documents i can find tell me that i should edit " C:\\Windows\\System32\\inetsrv\\config\\applicationHost.config ". But i'm fairly certain that this isn't the config file used by the IIS. The file still contains older application pools/websites and is missing newer ones. Also when i make a change in the IIS interface this doens't change the config file.

Any thoughts on what might be happening here ?

Answer 1

Exact same problem here, but finally found the answer: Applicationhost.config not showing changes ! Unbelievable but true answer: Notepad++ does not open the actual version of applicationHost.config . Restart IIS Manager, download and install Notepad2 x64 and everything should work as expected.
