Unable to modify machine.config file

I want to improve performance of my ASP.NET web application and want to change "processModel" tag in machine.config. But I am unable to modify "machine.config" file located at framework directory. Though I have disabled "readonly" permissio开发者_StackOverflown for the file, still it is not working.

You need to run the text editor that you are using to edit the machine.config file as Administrator.

Open it using NotePad++ (or) NotePad. You have to run Notepad first in Administrator more (right click, select Run as administrator), then open machine.config

For Visual Studio:

1. Right click on Visual Studio icon

(If you are right clicking on a taskbar icon, then you'll need to right click on the Visual Studio icon in the list as well)

2. Click Run as administrator
3. Within Visual Studio, click File->Open->File... (shortcut is Ctrl + O)
4. From here, navigate to your machine.config. For .net 4, it's probably here: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config
