So here is some information:

All desktops and laptops, number about 150, are Windows 7 x86. They all have JRE 6 installed presently.

I have created the GPO to install JRE 7, which works wonderfully. However the issue that I have is that I was under the impression that when 7 is installed 6 was automatically uninstalled and obviously I was mistaken. Is there something I have missed, or how can I go about making this happen where JRE 7 is installed and JRE 6 is uninstalled.

Any information you need, please let me know and I will get it posted asap.

Thanks for your help,

Was 6 installed by Gpo? If so the goto http://support.microsoft.com/kb/816102 check the remove package section.

Else you can create a start up script to run the uninstall commands.

I haven't took a look at the new JRE 1.7 so far but in older Versions it was possible to set propertys in the MSI
so that older JRE versions won't get "updated".
Look for propertys like JAVA UPDATE or JU. Many people confuse these propertys with an ability
to disable the Java Auto Updater but in fact they can allow/prevent the update of older JRE versions.

I've just downlaoded the new JRE as I also need to package it within the next days.
The names of the propertys are the same like in 1.6: JAVAUPDATE and JU when these are set
to '1' your old JRE installation will get updated.

JREs are designed to live side-by-side. Also, some apps search for explicit versions. Removing 6 might break these. I'd leave it where it is. It's not like it takes up much space!
