84. AutoRun/AutoPlay Does Not Work When A
CD/DVD Is Inserted
This problem last surfaced in Windows XP. At that
particular time the 'probable' cause was an
application called Roxio Easy CD Creator. Where
Windows XP was concerned simply updating Roxio cured
As has been said the last encounter with this
problem was in the early days of XP, so you can
imagine my surprise when, after inserting a DVD into
my DVD-Rom recently, I found, to my utter amazement,
that it wouldn't auto play
Both music CDs and even the Windows Vista DVD
were tried to see if they would Autorun/Autoplay
but, to my disappointment, all failed
On this occasion no Roxio software of any
description was installed on my system, therefore, I
couldn't blame that for my current demise. Finally,
through trial and error, the problem was traced to
the Windows Registry where, as if by magic,
something had actually turned the Autoplay option
If you have a similar problem then I would
suggest that you first check the Windows Registry to
see if the AutoRun/AutoPlay option has inadvertently
been turned off.
To check the registry proceed as follows.
Editing the registry can cause problems which may
render your PC unbootable. This is especially so if
you change keys that you shouldn't. Therefore, prior
to making any changes to the registry it is
suggested that you make a back up of the registry.
For more information on backing up the registry see

opening the registry editor. If you are the

enabled in this Registry key, then Locate

9/ If you are unable to locate this registry key
look for he following registry key
10/ Look at the entry NoDriveTypeAutoRun
(It is sometimes difficult to locate this particular
option in the maze of other registry entries,
therefore, I find that it is easier if one uses the
Find option. Click Edit on
the registry main toolbar and then,
from the drop down menu, select
Find. In the Find What
dialogue box type: NoDriveTypeAutoRun
and then click the Find Next
11/ If the value of this key is
0xb5, then AutoRun is turned off.
