When in guest browsing mode, Google Chrome won't save cookies, the browsing history, and other profile-specific data. This feature is useful in terms of privacy. It plays well with a shared user account at home, or in any other environment.

Don't be confused with Incognito mode and Guest mode. Incognito is a window that implements the private browsing feature. While it doesn't save things like your browsing history, cookies, site and forms data, it allows you accessing your profile, bookmarks, etc.

Guest mode acts as a new, empty profile. It doesn't allow accessing bookmarks or any other profile data. Once you exit Guest mode, everything related to your browsing activity is deleted from the computer.

When to use Guest Mode

The guest mode feature is useful when you often let other people to use your computer. Or, if you borrow a laptop from a friend, you can also use Guest Mode to ensure that you leave no browsing traces on that PC. The same is applicable to public computers you can find at a library or cafe.

Normally, you can access Guest Mode by clicking on your profile icon and then selecting Open Guest Window.

Starting with Google Chrome 77, you can enable a new BrowserGuestModeEnforced policy. When the policy is enabled, the browser will enforce guest mode and prevents users from using their profiles. Here is how to enable it.

  2. Extract its contents to any folder. You can place the files directly to the Desktop.
  3. Unblock the files.
  4. Double click on the Always_Enable_Guest_Mode_in_Google_Chrome.reg file to merge it.
  5. To undo the Guest Mode enforcement, use the provided file Turn_Off_Guest_Mode_Enforcement_in_Google_Chrome.reg.

You are done! The change will affect the current user only.

Once you apply the change, Google Chrome will always start in Guest Mode.

Note: The Registry files to apply the change for all users are also included. See below.

How does it work

The registry keys above modify the 32-bit DWORD value BrowserGuestModeEnforced under the key:

HKEY_CURRENT_USER\SOFTWARE\Policies\Google\Chrome

See how to go to a Registry key with one click.

You need to set its value data to 1 to enable the enforcement. Delete it to restore the default behavior.

In case if you need to enforce Guest Mode for all user account on your computer rather than for the current user, you need to create the BrowserGuestModeEnforced value under the key

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome

Before proceeding, ensure that your user account has administrative privileges.

Note: Even if you are running 64-bit Windows you must still create a 32-bit DWORD value.

That's it!
