How to Block Incognito Mode in Google Chrome

Incognito mode, also known as Incognito mode if you are a Google Chrome user, is a very useful tool that allows users to create a sandbox/private chrome window that runs separately from the main window and forget everything once you close button. However, if you are a school, public library, or business where you need to ensure that no unsaved research or activity is left behind on any of the computers, the best solution would be to ditch Google Chrome altogether. Right?

No, luckily there is no need to ditch Google Chrome, as there are much easier ways to block Incognito mode on Google Chrome depending on your operating system, as you will see below:

  • Click Start or Search and type “CMD” in the search field.

  • Once you see the CMD icon, select Run as administrator (select yes if prompted on screen), this opens a black CMD window with white text.

  • Now that you have CMD open, copy and paste the code below right next to C:WindowsSystem32>.
REG ADD HKLMSOFTWAREPoliciesGoogleChrome /v IncognitoModeAvailability /t REG_DWORD /d 1


  • Once you have pasted the code, hit enter, it will take a while before you see a message that the operation was completed successfully.


Just like you can use CMD to block incognito mode on Windows, you can use Terminal on Mac OS to do the same thing we’ve shown below:

  • In the Finder, click Go then Utilities.
  • In the Utilities window, find and open the Terminal application.
  • Once in the terminal, select the code mentioned below, paste it and press enter
defaults write IncognitoModeAvailability -integer 1z


You may need to restart Google Chrome to see the changes, now if you launch it and go to the menu you will see the incognito tab option is no longer listed there.
