Block URLs in Chrome or Chromium on Windows Without an Extension

11 Nov, 2021

1. Open RegEdit from the Start menu and create the following Registry Key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome*URLBlocklist*

2. For each URL you want to block just create a new String value, named by a number.

Example

Name: 1 Value: https://*.google.com

3. Set the command line flag --install-url-blocklist-handlers. Right click Chrome's shortcut, go to Properties, then to the Shortcut tab, and append the switch to the end of the Target value.

4. Restart your Chrome or Chromium based Browser.

All google.com subdomains will now be blocked.
