--args is an option to the OS X open command, you shouldn't need it on windows. My guess is:
start /b "" "C:\Users\User\AppData\Local\Google\Chrome\Application\chrome.exe" --record-mode
Report back if it works!
start /b "" "C:\Users\User\AppData\Local\Google\Chrome\Application\chrome.exe" --record-mode
Report back if it works!
"C:\Users\User\AppData\Local\Google\Chrome\Application\chrome.exe" --record-mode
