Enable or Disable Guest Mode in Google Chrome
Google Chrome’s Guest Mode lets you start a temporary browsing session. This means no history, cookies, or website data gets saved, so someone can browse without leaving any trace on your computer.
You can choose to enable or disable this Guest Mode. Enabling it allows anyone to use Chrome without accessing your personal saved information, like passwords or bookmarks. Disabling it stops new guest sessions from opening.
This feature is really handy for computers that multiple people use. It keeps everyone’s browsing private and secure. You might want to disable it if you want to make sure everyone uses their own Chrome profile and keeps their data separate.
Keep in mind, if a workplace or school manages your Chrome browser, they might prevent you from changing Guest Mode settings yourself.
Edit the Windows Registry to enable or disable Chrome’s Guest Mode. Navigate to Computer\🗝️HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome, create a DWORD value named BrowserGuestModeEnabled, and set it to 0 to disable or 1 to enable.
Enable / Disable Guest Mode in Chrome using the Registry
You can enable or disable guest mode in Chrome by changing a setting in the Windows Registry Editor. This method works if your computer isn’t already set up with specific policies that lock these options. To make these changes, run the Registry Editor as an Administrator.
If your registry keys are locked by an existing policy (a set of rules applied by an administrator), manual creation will fail. To make these changes, run the Registry Editor as an Administrator.
First, open the Windows Registry. Before you begin, it's a good idea to back up your registry (a record of your computer's settings) or create a System Restore point as a safety measure.
Go to this path:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
If you do not see the Google folder, right-click the Policies folder and create a new key named Google. Do the same for Chrome if it is missing.
Right-click the Chrome folder. Select New > DWORD (32-bit) Value. Name it BrowserGuestModeEnabled.
Browser Guest Mode, a privacy setting in Google Chrome version 110 and later, allows temporary users to browse without saving history or cookies. To disable Browser Guest Mode, locate the BrowserGuestModeEnabled setting and change its value to 0. To enable Browser Guest Mode, change the value to 1, which protects your personal browsing data.

To restore the default settings, delete the BrowserGuestModeEnabled entry. You may need to restart your computer for these changes to work.
Using Google Chrome ADMX Templates
Businesses and IT teams can manage guest mode settings for many computers using Google Chrome ADMX templates with the Group Policy Editor.

What are the disadvantages of guest mode?
Allowing guest users on a network can introduce security risks, primarily because it is harder to control what guests access and download. If not properly configured, a guest network might be exploited by malicious users to gain unauthorized access to sensitive data or to infect the network with malware.
