Google Chrome can be started in Incognito mode by appending a command line switch to the Target field, similarly, beginning from version 77, the same browser can also be launched in “Guest browsing mode” via a command-line flag, FYI, this is new and previous Chrome versions not supported this.
To browse privately, Chrome offers Guest mode and Incognito mode. With former, you as a user allow others to surf the web in Chrome on your device, and they can’t see or change your profile’s info. This mode is suitable when you use a public computer at cybercafe or Coffee shop or if you’re using someone else’s device.
In Incognito mode, you can browse privately, where like in guest mode, browsing history, cookies and data filled in forms will be cleared when you exit, but downloads and bookmarks will be kept. Here, people who use your device can’t see your activity.
While Guest mode can be launched from within Chrome browser by selecting “Open Guest window’ option in the user menu, how about creating a dedicated shortcut for it on the desktop so that you can use it for others whenever needed?.
Launch Google Chrome in Guest browsing mode by default
1. Ensure you’re using Chrome stable 77 or later, right-click on its shortcut on the desktop
2. Select Properties, in the Target field, after \Chrome.exe ” give space and add below switch as shown in the below screenshot
The total string in the Target field should be like this
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --guest
3. Click Apply, when Chrome asks for administrator permission, click “Continue” and OK.
Now if you launch Chrome, it opens a new guest window instead of a regular window.
Note: To undo this and to launch Chrome browser normally like before, delete command line switch we’ve added above in the second step and apply. When you relaunch Chrome, you’ll be asked to “Browse as Guest” or “Add Person”, click on your profile frame to launch Chrome normally.
