Some users want each time they open Google Chrome. It would automatically open into private mode. So how to get done? In fact, there is no setting in Chrome to do it, but the following instruction could help you to solve this problem.
1. You need a shortcut to Chrome on your desktop, you can make another one and call it something like Chrome Incognito.
2. Right click on the shortcut and select “Properties”.
3. In the “Shortcut” tab, you need to edit the box labelled “Target:”
Go to the end of the line in that box and add a space, then 2 dashes (not 1) then the word incognito. So the end of the target should be Application\chrome.exe –incognito.
4. Click “OK” or “Apply”, now whenever you start Chrome from that shortcut it will be in Incognito Mode.
