Start Google Chrome as Guest
Solution 1:
You can use the command:
chrome.exe --guest
Solution 2:
I'm not sure if it's currently possible to do this. The closest alternative I've found is to right-click your Chrome shortcut, click "Properties", then append --profile-directory="Guest Profile"
to the "Target" field. That will not open Guest mode directly, but it will open Chrome to the profile selector screen, where guest mode is one click away.
Solution 3:
You can do this by going to the Settings.
Under 'People' section, click "Add person...", you can name it as "Guest" or anything you want, make sure the checkbox "Create a desktop shortcut for this user" is checked.
Once you've done that, there will be a shortcut in your desktop. You can pin it on your taskbar or just leave it there on the desktop for others to use.
So far, that's the only way I know how to do this. Hope it helps.
