Just gonna plug hostsman, which has been doing this on windows since forever:<p><a href="http:&#x2F;&#x2F;www.abelhadigital.com&#x2F;hostsman" rel="nofollow">http:&#x2F;&#x2F;www.abelhadigital.com&#x2F;hostsman</a><p>Lets you chose which lists to use, and automatically update those lists.  Also makes it easy to temporarily disable your rules if you need something that&#x27;s blocked.  Has a button for flushing the DNS cache.
