I'm using my personal laptop that runs Windows Vista. I want to block a website from my computer so I won't play it. I followed all the instructions on how to properly go to the hosts file and put in the information. However, whenever I save, it says it cannot create the file, though there is already a hosts file. I also run Notepad as administrator and make sure to save the file as all files. Also, this is the only account on this laptop, so it should be admin. Any way I can fix this problem?
