How to block adult content on Windows?
Protecting your Windows PC from websites with explicit content and unwanted digital distractions is essential for staying focused, maintaining your mental well-being, and ensuring your household's online safety. Windows offers powerful built-in tools and network settings that allow you to block adult content without purchasing additional software
In this guide, we present two free and highly effective methods for restricting access to adult sites on Windows
Method 1: Blocking adult sites via CleanBrowsing’s "Family" DNS (system-wide protection)
The fastest and most reliable way to filter explicit content across all web browsers (Chrome, Edge, Firefox, Brave) is to configure CleanBrowsing’s "Family Filter" DNS directly within Windows network settings
Step 1: Open Network & Internet settings
Click the Start menu and select Settings (or press the Win + I keys).
Click Network & Internet
Select Change adapter options (or click your active Wi-Fi or Ethernet network connection)
Step 2 : Access TCP/IPv4 properties
Right-click your active connection (Wi-Fi or Ethernet) and click Properties
Locate "Internet Protocol Version 4 (TCP/IPv4)" in the list, select it, and then click the Properties button located below
Step 3: Enter the "Family Filter" DNS addresses
Select the option "Use the following DNS server addresses :"
Enter the following IP addresses for the CleanBrowsing Family Filter :
Preferred DNS server: 185.228.168.168
Alternate DNS server: 185.228.169.168
Check the "Validate settings upon exit" box and click OK
For IPv6, enter the following IP addresses for the CleanBrowsing Family Filter :
Preferred DNS server: 2a0d:2a00:1::
Alternate DNS server: 2a0d:2a00:2::
Click OK
Note : These DNS servers automatically block adult sites and domains with explicit content, while also enabling "SafeSearch" on Google, Bing, and DuckDuckGo.
Method 2 : Configure Microsoft Family Safety (built-in parental controls)
If multiple users or children share the same Windows computer, Microsoft Family Safety provides user-account-level protection to filter inappropriate web content and limit screen time.
Step 1: Add a family member account
Go to Settings > Accounts > Family & other users
Click "Add a family member" and create or enter a Microsoft account for your child or the secondary user
Step 2: Enable content filters
Open your browser and sign in to family.microsoft.com
Select the profile of the family member you wish to restrict
Click "Content filters" in the left-hand menu
Enable the "Filter inappropriate websites and searches" option
Step 3: Block specific websites and enable SafeSearch
Ensure SafeSearch is enabled
In the "Always blocked" section, you can manually add specific domain URLs to block them permanently
Summary and best practices
Combining a secure DNS filter (CleanBrowsing/Cloudflare Family) with Microsoft Family Safety creates a robust, multi-layered defense system on your Windows PC
Lock down settings : Ensure your primary Windows administrator account is password-protected so that secondary users cannot modify network settings
