What Is NSFW?

Well, NSFW stands for “not safe for work.” When used correctly, ‘not safe for work’ is a warning that highlights a link to a video, webpage, photo, or audio clip that contains unsuitable content. Although the word is usually linked with pornography. Also, it’s used as a warning indication for violent, foul, harsh, or also politically charged content.

Besides its literal meaning (not safe for work), the NSFW is used to save you from any sort of public embarrassment. You might view it in the title of a YouTube video, or else in the email header, etc.

In some situations, NSFW is used to highlight that a webpage might make you uncomfortable—that’s how broad of a word we’re dealing with. In these cases, NSFW is certainly accompanied by a “trigger word” or “TW” label. A video having brief images of war, for instance, may be labeled “NSFW TW: War,” or something to that effect.

Follow the ways to block adult websites on Windows:

Windows Parental Control

The simplest trick to block adult sites or any time-wasting sites (such as Reddit or Instagram) is to use Parental control in Windows 10. Make sure you want an MS account and then create various users for yourself or your children.

  • Initially, create a local user account for your kid.
  • To do so, head over to Settings > Accounts > Family & other people. Choose ‘Add a family member’, and then create a new user for your kid. Keep in mind, you want to add an email address for your child here, so make sure you have one handy.
  • After this, head over to the Windows 10 family settings and then log in, to manage your kid’s accounts directly.
  • Once you successfully login in you’ll then view a dashboard that allows you to set screen time limits, filter content, block sites, etc. Here you want to block websites, so tap on Web browsing, select Block inappropriate websites. As it’ll block adult content on Internet Explorer or Microsoft Edge and you can then customize it to stop your child from launching Firefox or Chrome browser. However, it’s far from perfect,  your children can always, use proxy sites or install any new browser to bypass this.

Block Adult Websites On Windows Via OpenDNS

The effective, fast, simplest, and easiest method to properly block and filter content is to use the OpenDNS service. OpenDNS is originally a public DNS service that can filter, intercept, or block the content according to your settings. If you don’t know about DNS service then it can translate the human-readable web address such as google.com to a machine-understandable IP address i.e For this example, we’ll use OpenDNS to block bad content, however, there are other DNS providers such as Clean Browsing. The steps are quite similar:

  • Initially, head over to the official site and then sign up for a free account.
  • After you are successfully done signing up, OpenDNS will provide you the IP addresses of its DNS service. We should try to use these IP addresses in our PC or router to initiate using the OpenDNS.
  • Hopefully, OpenDNS offers a set of instructions on how to modify DNS addresses on a PC or on a router. Just tap on the correct option as given below:
    • Home Routers: If it is your home router then choose this option. It will redirect you to a page where you can find steps for your specific router.
    • Computer Workstations & Laptops: This option provides steps on how to modify the DNS address on your Mac, Windows, or Linux computer. I will explain to you how to modify the DNS address in Windows, just follow the instructions below.
    • Smart Devices: This option displays the steps for other smart devices such as PlayStation, Xbox, Smartphones, Apple TV, etc.
Configure OpenDNS
  • If you want to set up the filtering, then tap on the link “Dashboard” located on the top navigation bar. On the other page, move to the “Settings” tab. However, your recent IP address is already added in the blanks. Just tap on the button “Add Network.”
  • A prompt appears and asks you to input a friendly name to easily recognize the network. So, input the name and tap on the button “Done.” If you are working with a Dynamic IP address, then choose the checkbox “Yes, it is dynamic” and then tap on the link “OpenDNS Updated for Windows” to install the OpenDNS software.


  • That’s all, you’ve successfully added the network. Now try to install OpenDNS Updater and then log into your account so that it can update the IP address automatically using OpenDNS if you have a Dynamic IP address (IP address that modifies every time you enable your internet).
  • After you successfully create the network, tap on the IP address to configure it.
  • Now, choose the radio button “Custom,” choose the checkbox “Pornography” and then tap on the button “Apply” to save the changes. That’s all about it.

Qustodio blocks all the bad content like gambling, pornography, violence, etc by default. If you wish to edit the block settings, head over to the “Rules” page. As you can view, some categories of websites are restricted by default.

If you like to further restrict any website category then tap on the category name. You can then choose the option “Block website’s category” and you are good to go.
