To edit host file, follow these steps:

• Click Start, click All Programs, click Accessories, right-click Notepad, and then click Run as administrator.
  
• If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
  
• Open the Hosts file or the Lmhosts file, make the necessary changes, and then click Save on the Edit menu.

Open Notepad with Administrative privileges by clicking Start, All Programs, Accessories, and then right-click Notepad and select to open as Administrator.

Now that Notepad is open with Administrative privileges browse to (C:\Windows\System32\drivers\etc) in Notepad and open the hosts file.
