Running Vista 32 bit. Have deactivated UAC and trying to edit the Hosts files located in C:\Windows\System32\drivers\etc. I'm using notepad to make the changes. When I try to save, I get a message "C:\Windows\System32\drivers\etc\hosts file. Make sure that the path and file name are correct. " When I try to save in a different location, notepad only allows me to save as .txt? Is there some way to save as per original file extension?
