USB How to copy an app and run??

I thought that applications are exedcuted directly from a USB drive in essentially the same way as from any other disk drive. Some software needs to be installed and for software such as that, copying to anotjer drive is not likely to have any benefit. If the software needs installation, then it can be installed directly from the USB drive.

If it were me, I would look to see if there is an autorun type of capability instead of using WMI. There might be something that works that does not require anything special to be installed in the system first. WMI would require that a program using WMI be installed already.

Of course I probably misunderstand the requirements.

We did, of course, deal with the copying aspect in this previous thread:

There is some WMI code in the last post in this thread which can detect when a USB drive is plugged in:
