OT:Java Update question

Ok, I've updated to Java 1.5.09 and uninstalled 1.4.xx
I've found a java 1.5.09 .msi file in :
c:\documents and settings\time\local settings\application
data\sun\java\jre1.5.0_9

My question is now that the install is done is this still needed.
I did the install from the downloaded .exe
My assumpition/hope is that this file was exctracted as part of the install
process and is no longer needed. I have put it in my trash bin and
everything is fine. But someone raised the question that this file might be
needed for when I have to do an uninstall after the next update.

Facts? opinons? Is this a remenant of the install process? Is this needed
for the later uninstall? Do other people have this file in this location? I
would think if it were needed for the uninstall process it would be located
in a different location, e.g. \all users\application data ..., Program
Files\Java... , Windows\...something.

I thought most things in \user name\local settings\application data\ were
for the individual user, not system wide programs?

Thanks in advance,
