Fiddler on Windows 10

I've previously written about Fiddler here:
http://stgaup.blogspot.no/2013/03/fiddler-tricks.html

When installing Windows 10, you create an account which is not connected to any external host in any way. Later however, you probably associate your account/Windows 10 instance with your Microsoft account. Afterwards you will use your Microsoft account when logging in.

In my previous post I mentioned one could make Fiddler work by running the app pool on the same account at that on which Fiddler is running (and which you are most likely logged on to).

But there are now two accounts it seems:

• the one you created while installing, 
• and the Microsoft account,  

so which one should you use when running Fiddler?
Turns out it works with the Microsoft account.

Username: someone@hotmail.com/outlook.com/live.com etc.
Password: the password associated with the Microsoft account.

Fiddler tricks

Capture traffic from localhost:

• Add a dot after “localhost”, so it becomes http://localhost.
  • This does not always work. On my Windows Server 2008 R2 box, it does not.
• Access your web using the (netbios) machine name.
• Access your web through the fiddler proxy: http://ipv4.fiddler/AppName…
• Run your web’s application pool under the same account that fiddler is running under, ie. the account you are logged on as.
• NB! This also has the MAJOR benefit that you will see web service calls from your website.
• IIS Express by default runs as the logged on user, so Fiddler will capture traffic.
