Yeah, there are bunch of utils to clean temporary IE files, but you can solve the the problem with one simple batch file.

You can include :

deltree/y c:\windows\temp
deltree/y c:\windows\tempor~1
deltree/y c:\windows\cookies

you can also delete history, recent docs, or NN temp the same way.
Of course you can delete temporary IE files from DOS mode only, so make shortcut for that file to reboot in DOS mode. Or add to autoexec.bat on every WS.

As simple as that
