Active Scripting (formerly known as ActiveX Scripting) is the technology used in Windows to implement component-based scripting support. It is based on OLE Automation (part of COM ) and allows installation of additional scripting engines in the form of COM modules.
ActiveX was controversial from the start; while Microsoft claimed programming ease and good performance compared to Java applets in its marketing materials, critics of ActiveX were quick to point out security issues and lack of portability, making it impractical for use outside protected intranets. [10] The ActiveX security model relied almost ...
It is intended primarily for low-cost devices, and is otherwise identical to Windows 10 Home.

To change the display language, the user will need to ...
Later versions of Internet Explorer prompt the user before installing an ActiveX control, allowing them to block installation. As a level of protection, an ActiveX control is signed with a digital signature to guarantee authenticity. It is also possible to disable ActiveX controls altogether, or to allow only a selected few.

In Windows 7 and later, significant hardware changes (e.g. motherboard) may require a re-activation. In Windows 10 and 11, a user can run the Activation Troubleshooter if the user has changed hardware on their device recently. If the hardware has changed again after activation, they must wait 30 days before running the troubleshooter again.
This concept of dynamic extensibility is taken to the extreme with the Component Object Model, the underpinnings of ActiveX. In Windows 1.x, 2.x and 3.x, all Windows applications shared the same address space as well as the same memory. A DLL was only loaded once into this address space; from then on, all programs using the library accessed it.
It is the primary scripting language in some operating systems including OS/2, MVS, VM, AmigaOS and is used for macros in some software including SPF/PC, KEDIT, THE and ZOC. With an engine installed, Rexx can be used for scripting and macros in programs that use a Windows Scripting Host ActiveX scripting engine (such as VBScript or JScript).
