Hi,<br />
<br />
there is probably a GroupPolicy which adds the settings to Internet Explorer and deploys adobe reader. Have you check the OU where the computer is for Groupolicys?<br />

<div>
yip, it sounds like a GPO setting, <br />
run gpresult /Z &gt;gp.txt<br />
open the gp.txt file and search to proxy settings or startup installation scripts.<br />
This will tell you in which GPO to look and the settings that needs to be modified.

thanks, @ dvt_localboy, that command doesn't seem to work for me, <br />
Anyhow, I think we on the right track with this whole GPO.<br />
I suspect what's happening is that the PC is being joined to the domain, and it inheriting the the computer OU gpo's<br />
<br />

Am I correct in uderstanding that all machines in the computers OU as above will inherit GPO's listed in right window pane, and if the machine is joined to DC but moved to the Computers64bit OU it will not inherrit the GPO as the block inheritance option is selected?<br />
<br />
Kindly advise?<br />

GPRESULT definitely ships with Windows 7, so can you tell me what error you get when you try to run the command?<br />
<br />
You've got a lot of policies in those OU, and a whole lot more probably exist higher up.<br />
The GPRESULT information will point you directly to the GPO that is causing these application to install.<br />
<br />
If inheritance is blocked then only the GPO's specifically applied on that OU level will be applied to the machine.<br />
<br />
By default all new computer accounts are stored in the Computers container, which is just off the root of the domain. Containers cannot have GPO's applied to them, so machine that are there won't be applying the GPO's.

Windows 7 is an operating system from Microsoft. Features include multi-touch support, a redesigned Windows Shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and performance improvements.
