Windows 8 Custom Autorun Flashdrive

Windows 8 Custom Autorun Flashdrive

I recently got a new flash drive that I am devoting entirely to my
programming work (mainly python).
Because I use my flash drive all of the time, I have a lot of important
documents that I have on my flash drive, that would be disastrous to lose.
The nature of my job, however, is that I am constantly switching
computers, and sometimes don't have time to upload documents I worked on
to the cloud as a backup. Plus downloading of some of my projects can take
quite a bit of my time if I'm working on a large project, so using only a
cloud storage system like dropbox would be bad. What I want to do is
create a python autorun script so that the moment I plug in my flashdrive,
it uploads the program files in the background while I work in the
foreground. The actual python script I will ask about later, if I have
troubles.
Right now, however, my issue is getting autorun to work. I looked up a
bunch of tutorials and followed their instructions to the letter about
creating autoruns and batches and such, but every time I try to run the
program when I plug in my flashdrive, Windows 8 (my home computer) tells
me there's a problem with the flashdrive and asks if it can scan and
repair it.
autorun.inf:
[Autorun]
open=autorun.bat
icon=python.ico
label=PythonDrive
autorun.bat:
"Portable Python 2.7.5.1\Python-Portable.exe" "autorun.py"
I have the files all in the main directory of the flashdrive. The icon and
label command seem to work for my flashdrive, but if I get rid of the open
command, the computer still complains. I would prefer just executing the
python without a batch, but I was hoping that a batch file might work
better than a python file being executed from portablepython. the batch
file does work, if I manually open it.
I found this article which mentions that you can no longer (in windows 7)
use the open command in autorun.inf. Is this true? If so, how do I work
around it?
