This isn’t hard to do, but you have to do it with a shortcut (may be able to do with command line, but I know this way works).
Make a shortcut to Chrome (or copy the one in your start menu to the desktop (or anywhere you can find it easily). Open the shortcut’s properties. In the “Target:” field, key/scroll/clock to the end of the path, hit the space bar, then add --profile-directory="Guest Profile"
replacing Guest Profile with the name of the directory in which the desired user’s data is stored (double quoted).
Note: this may be different from the profile’s name, check this path first (substitute your windows username for ):
``C:\Users<username>\AppData\Local\Google\Chrome\User Data`
Once you have made this shortcut, simply have Listary target it instead of chrome.exe.
Hope this helped…someone.
