windows 7 - hosts file and unblocked subdomains

I modified hosts file to block google.com and its subdomains but it blocks only the main domain name. It does not block the subdomains. Windows 7 Starter

127.0.0.1 google.com

It blocks google.com but dows not block www.google.com

Then I tried this one: 127.0.0.1 *google.com It didn't helped.

Answer

The hosts file is very basic, and by basic i mean BASIC. You are going to have to do

127.0.0.1 google.com
127.0.0.1 www.google.com
127.0.0.1 wave.google.com
127.0.0.1 docs.google.com

etc

If you are trying to pull a prank, use that, if you want to get serious, you need to invest in a network firewall or some such that will allow you to block domain names.
