Close programs on exit, help required

Hi,

I have searched the forums but...

I am completely new to any sort of programming and have managed to make a batch file (which will launch on hitting "enter" when I insert the USB drive on XP SP2 computers) to start PStart to launch my apps, Cryptainer mobile (seems rather like TrueCrypt and as I had a paid for version so can have containers bigger than my 1Gb drive I am using this)with my apps encrypted on it and CruzerSync (which came with the Sandisk Titanium drive) to carry Outlook emails and folders of data from My Documents at home.

However, I would like to close any open apps and the above with one click so I can exit my drive.

There are various threads associated with this, which are beyond me, and I cannot configure USB Safe Unmount.

Is there another SIMPLER way to this?
It does not need to be completely portable, as long as no personal data is left.

Yours

Roger
