I have had mixed results over the years using the asterisk in kixtart, and just learned to work around it. Here is how I would do it (untested)

 Code:
for each $file in dirplus("C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup","/f bat")
  if instr($file,"Drive")
    ? $file 
    ;del $file
  endif
next


You will need to unrem the del line once you have tested it, and you will need to copy the dirplus UDF linked below into your script.
