New Web Application button is disabled in SharePoint 2010

I am having a fresh installation of SharePoint 2010 on my Windows 7 machine, when I tried to create new web application for creating a site collection, but the New Web application icon is disabled/greyed. So for this issue, here is the fix,

1. Go to control Panel (win + r  shortcut key for run textbox and type control)
2. Click on System and Security
3. Under “Action Center” section , click on “Change User Account Control settings”
4.  Scroll down the scrollbar to “Never Notify” as shown in below figure
5.  Click on Ok
6.  Restart the system ( This step is necessary)
7. Now open the central administration as administrator
8. Now the New Web Application button is enabled
