I had a similar problem where i want to use google chrome for browsing and debugging for work and chrome is pretty original when it comes to sessions. I wrote this small batch script to duplicate the default profile, clear session information and then use the new profile. Old duplicate profiles are also cleared before the new ones are created. The result is a new session with all the old profile stuff.
@echo off
rem folder prefix for the new profile folder
set folderNameStart=profile_
rem generate and format the date creating the new folder name
For /f "tokens=1-6 delims=/ " %%a in ('date /t') do (set mydate=%%c%%b%%a)
For /f "tokens=1-2 delims=/:" %%a in ('time /t') do (set mytime=%%a%%b)
set folderName=%folderNameStart%%mydate%%mytime%%random%
rem set the profile path and the folder destination as well as the directory to
delete
set profilePath="C:\Documents and
Settings\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default"
set profileDestination="C:\Documents and
Settings\%USERNAME%\AppData\Local\Google\Chrome\User Data\"%folderName%
set profileLocation="C:\Documents and
Settings\%USERNAME%\AppData\Local\Google\Chrome\User Data\"
rem iterate through directory and delete all the existing profile folders
CD %profileLocation%
echo %profileLocation%
for /D /r %%G in ("%folderNameStart%*") do rmdir /q /s "%%G"
rem this will copy the old profile directory
echo D | xcopy %profilePath% %profileDestination%
rem delete the session storage and its contents if its exist
rmdir /q /s "C:\Documents and Settings\%USERNAME%\AppData\Local\Google\Chrome\User
Data\%folderName%\Session Storage"
rem start google chrome with the new profile folder
start "Chrome" "C:\Program Files\Google\Chrome\Application\chrome.exe" --profile-directory="%folderName%"
