Yes, but you must be aware of this issue: 1. You disable autorun.
2. Double-clicking the USB in My Computer *will* autorun!!!

What I described runs code AFTER you have disabled autorun.

I have seen so much junk documentation on autorun that my head is spinning.
I think the key point for most users is what they click when they insert a
USB disk the first time. Of course I don't remember exactly what happens,
but I recall a window where you got various options.

Following are some clues, but I have not got to the bottom of this issue or
found the "best" article:
