Group Policy ADM template to implement the workaround from Security advisory 973472

  • Article

Hi everyone!

Axel here from the IE Team with a quick Group Policy ADM template to help implement workaround described in security advisory 973472. I am also including the .reg file and .adm templates for both x86 and x64 versions.

Please note:   This is an “as is” template, so feel free to tweak it as needed.

Important: This policy requires that you disable filtering in the group policy editor. See steps below on how to set this up.

How to load the Custom ADM Template?

  1. To start Group Policy, click Start and then click Run. In the Open box, type GPedit.msc or GPMC.msc if from a Domain policy and then click OK.
  2. Select Administrative Templates from the Computer Configuration branch.
  3. Right-click the Administrative Templates branch, and then select All Tasks.
  4. Select Add/Remove Templates.
  5. Click Add.
  6. Load the ADM templates.

Please note: Windows 2003, Windows XP will display the policy under: Administrative Templates > New Policy

Here is how you disable the Group policy filer:

  1. Right click on the Policy and select View > detail > Filtering
  2. Remove the check mark from the check box next to "Only show policy settings that can be fully managed"
  3. You should see the template now.
