You’ll now be presented with the following add-on information: name, publisher, status, type and file.
Step 4: Click on the ActiveX control you wish you disable, and then select the Disable option. You’ll notice the selected ActiveX control’s status changes immediately to Disabled.
To delete an ActiveX control, follow the steps outlined above but click the Delete button instead of the Disable button. This will, effectively, uninstall the control.
Note that if you disable an ActiveX control, it can easily be re-enabled by following the steps outlined below. However, deleting a control is similar to uninstalling a program - in other words, there's no easy way to get it back. To get the control back, you'll probably find that you'll need to uninstall and then reinstall whatever program loaded it in the first place (Adode Reader, Adobe Flash or whatever).
Note too that not all controls can be deleted - in some cases, the delete option will be dimmed out and not available. This is because you can only uninstall controls that you installed yourself - you cannot delete the ones that came loaded with Windows.
