How to Block Websites on Windows 11 (Complete Guide)
Want to block social media to focus, restrict certain sites for your kids, or simply cut distractions? Windows 11 offers several ways to do it, from the simplest to the most robust.
Method 1: Edit the Hosts File (No Install Needed)
The Windows hosts file lets you block any website by redirecting its domain to a non-existent address. Most effective method, no software needed.
- Open Notepad as administrator
- Go to File → Open and navigate to:
C:\Windows\System32\drivers\etc\hosts - At the end of the file, add one line per site:
127.0.0.1 www.facebook.com127.0.0.1 facebook.com - Save the file
To unblock, simply delete those lines.
Method 2: Microsoft Family Safety Parental Controls
If you want to block sites for a child, Microsoft Family Safety is the best option: official, free and easy to use.
- Go to Settings → Accounts → Family
- Add the child account as a family member
- Configure web content filters at family.microsoft.com
Method 3: Browser Extensions
To block sites only in the browser, these free extensions work well:
- Cold Turkey — feature-rich, supports schedules and block lists
- LeechBlock NG (Firefox) — schedule-based blocking with time limits
- BlockSite (Chrome/Edge) — simple and effective
Method 4: Router-Level Blocking
Blocking at the router level affects all devices on your network. Access your router settings (usually at 192.168.1.1 or 192.168.0.1), find URL Filtering or Parental Controls, and add the domains to block.
How do I block YouTube on Windows 11?
Use the hosts file method by adding: 127.0.0.1 www.youtube.com and 127.0.0.1 youtube.com. Or use a browser extension like BlockSite to block it in Chrome with time schedules.
How do I block social media to focus at work?
The best option for productivity is Cold Turkey: create block lists with schedules (e.g. block Instagram from 9am to 6pm). The basic version is free.
Can a child bypass the hosts file block?
Yes, a tech-savvy user can edit the hosts file or use a VPN. For robust child protection, combine Microsoft Family Safety with router-level blocking, which is much harder to bypass.
Conclusion
For personal productivity blocks, use the hosts file or an extension like Cold Turkey. For parental control, combine Microsoft Family Safety with router blocking for maximum effectiveness.
