How to block adult sites on Windows
Set up Windows
- 1Open Settings → Network & internet → Wi-Fi (or Ethernet) → Hardware properties.
- 2Next to DNS server assignment, click Edit, choose Manual and switch on IPv4.
- 3Enter the preferred and alternate DNS below. Set DNS over HTTPS to On (manual template) and paste the template.
- 4Click Save, then install the ZenTab extension in Chrome for urge challenges and Strict Mode.
185.185.https:/Browsers can bypass the system filter with their own secure DNS. In Chrome, Settings → Privacy and security → Security → Use secure DNS should be off or set to the address above. In Firefox, set DNS over HTTPS to Off or to the same address.
Use a standard (non-admin) account day to day and let someone you trust keep the admin password. Changing DNS needs it.
Check that it worked
Open zentab.live/protect on this device and tap Test this device. It checks that known adult sites are unreachable without opening or showing anything. Sign in with your Gmail first and the result appears on your dashboard, next to your other devices.
Frequently asked questions
Do I need to do this for every Wi-Fi network?
Windows stores DNS per network adapter, so set it on Wi-Fi and Ethernet. On a laptop that joins many networks, check the setting stuck after connecting somewhere new.
Why install the extension as well?
The DNS filter blocks adult domains. The extension adds what a filter can't: urge challenges instead of a dead end, SafeSearch, Strict Mode, and a count of every urge you beat.
Protect Chrome on your computer too
ZenTab blocks adult sites in Chrome from the moment you install it. Pro adds urge challenges, SafeSearch everywhere and a 30-minute lock, so a weak moment passes before you can switch it off.
