Tips for installing ActiveX include using an account with administrative privileges, or making sure that the administrator has enabled ActiveX functionality from the Policy Editor dialog box, and blocking the installation process of ActiveX controls from websites that aren’t trustworthy. Other tips include avoiding the installation of too many ActiveX controls to reduce security risks and managing system-wide ActiveX controls once they’re installed by accessing the Manage Add-ons screen in Internet Explorer or configuring values via the Policy Editor.
Enable the ActiveX functionality by configuring the ActiveX Installer Service to approve the installation process for trusted websites. To do this, press R and the Windows key at the same time, type “gpedit.msc” in the Open field, and click OK to access the Policy Editor dialog box. Click on Administrative Templates, double-click on the Windows Component and ActiveX Installer Service folders. Right-click on the Approved Installation Sites for ActiveX Controls entry, click Edit, and select the Enabled option. Click on the Show button, add the desired URLs, and configure the values that control ActiveX installation.
To manage ActiveX controls once they’re installed, click on the gear icon in Internet Explorer, click Manage Add-ons, and select the Downloaded Controls option from the drop-down menu. Double-click on the desired ActiveX control, add the websites on which you want to allow it to run, or click Remove to uninstall it. Consider removing unnecessary ActiveX controls in case the ActiveX Filtering functionality fails to mitigate security risks.
