Arduino - Serial IO: Arduino works but then is not accessable in Windows

If you're writing a library that communicates to windows you might find that the Arduino becomes unavailable until you remove it and it steps up in the com port index.

Fix: You need a handshake between the Windows and the Arduino.  The windows app needs to tell the Arduino to start sending data.

Why:
What is actually happening is if you're sending a constant stream of data, windows assumes it is a mouse and changes the driver!

You can buy windows online and create a flash stick or DVD disc.  It is possible to upgrade from earlier versions of windows to windows 8 without any discs too.  I would recommend a fresh installation if you want to maximise your performance potential.  Get windows 8.1

Boot process

Start the computer with the flash stick or the DVD for windows 8 in the drive.  If a windows 8 logo does not appear, you will have to find specific information on how to enable a boot override to start the setup from the media you have selected.

Be patient on the initial boot of the windows 8 disc, an image will sit on the screen for quite a while.  There is no progress bar without an SSD or dated hardware in the installation procedure can be slow to get started.  The computer will restart several times before launching the operating system for the first use.
