If you simply go to Tools > Startup > Display Database Window, and disable it then in next start up it won't show the Database Window but if someone Hold the Shift key when opening the database then it will be Bypassed! So your tables will be in reach.
This is important in Multi User Databases and especially in 2007 MS Access Version Databases which User Level Security System is omitted to don’t let Users to access Tables and change the data on purpose or not.

Be careful to make a back up of your Database first if you want to use this Code.
