Not to block a website, not to block social websites like Twitter or Facebook, but to block the whole internet. And while the program is running, you can do nothing about it. It's a self-control program.

Is there any software on Windows that can block the whole internet?

Edit: No longer free requirement.

    do you need local area network access or should this be disabled too?

  • @SeanCheshire That does not matter too much...Frankly, I haven't think about this. But that's a very nice question. Commented May 20, 2014 at 13:42
  • @AveMaleficum if you don't care about network connection, just disable the ethernet adapter that is used for internet connection.

You would need Web Filtering software. The first one I found was http://www1.k9webprotection.com/ which has time restrictions, and is free to home users (get a licence key from their Get K9 Now page. If you want to search for other free programs, then searching for free web filter -trial should get you more choices.

Retaining below instructions for other users reference

To restrict all access, disable the network adapter.

If you want to allow the LAN, but not the internet, go to the propertied, fill in the IP address and Mask, and remove the Gateway:
enter image description here

If you don't know what the IP address and Mask are, open up a command prompt ( WIN+R, then enter cmd), and type ipconfig

you will get something that looks like this:

  • No, that't not what I mean, I am sorry, maybe my question is not clear, what I want is a software that can disable the internet and you can do nothing about it. It's a self-control program. I am not asking how to disable the internet. Commented May 20, 2014 at 13:57

Perhaps you are looking for an app like Toggle Your Internet or Let Me Work or Internet Off by CrystalRich? There seem to be a lot of 'roll your own' type scripts and such out there for Windows systems as well - these essentially carry out the steps that @SeanC has laid out in his post above.

  • Links would improve this answer.

  • @Menasheh - you are correct, thank you for the comment. If I remember correctly as a new user I was not able to include links in my post. Also, some of the potential links for these kinds of tools were of dubious quality and/or integrity.

Hi you can use Blacklist or Whitelist settings in Firewall to control internet access of applications.

App name: Firewall App Blocker, tiny & easy to use app (just drag & drop the applications).


To block individual sites, you can modify hosts file, add the domain you wish to block and map ip address to or
