the /Q keeps it from prompting you to delete (i.e. Press Y/N to confirm) which is required in the batch file, or each time it runs it will want your input:
you can d:
del "C:\Documents and Settings\USERNAME\Local Settings\Temporary Internet Files"\*.temp /Q
del "C:\Documents and Settings\USERNAME\Local Settings\Temporary Internet Files"\*.wav /Q
del "C:\Documents and Settings\USERNAME\Local Settings\Temp"\*.tmp /Q
del "C:\Documents and Settings\USERNAME\Local Settings\Temp"\*.temp /Q
del "C:\Documents and Settings\USERNAME\Local Settings\Temp"\*.wav /Q
etc for anything you want to remove then save the file and schedule as above - > save as "all files" and save it is MyBatchName.bat
