Change a RemoteApp Program icon in Windows 2012 R2 RD Web Access, RDS

while working for AX, RDS setup, I had to add one App and change its icon to something meaningful.
so I followed below link, but got strucked on the calculation to get the icon index

I have used the powershell command, but with a trick.
I just used the tool (http://www.nirsoft.net/utils/iconsext.html) to get the icon out and saved in the desired location.


open the tool and select the Icon, in my case it is Internet explorer.

now copy the icon file and paste in the location "C:\Windows\RemotePackages\CPubFarms\QuickSessionCollection\CPubRemoteApps" and rename as per your app icon. this should reflect in RDS browser.

you can see the icon in RDS server itself, but for modified icons it does not reflect.

select the Remote App and select properties, then see the icon as highlighted.
