Overview
This category disables the Application Compatibility (AppCompat) framework on Windows.
The Application Compatibility (AppCompat) framework is a feature in Windows that collects data about application compatibility. This includes gathering information about application crashes, issues, and other operational details to help improve the compatibility of applications on Windows 1.
It is controlled by a set of policies within the Microsoft Windows operating system aimed at enabling applications designed for older versions of Windows to function properly on newer versions 1.
However, the Application Compatibility framework involves various forms of data collection that may be considered invasive from a privacy standpoint 1. It can potentially be exploited to reveal more data about your application usage or to inject your computer with malware 2 3 4.
By disabling the AppCompat framework, this script contributes to enhancing users' privacy by limiting potential data collection and exposure to malware exploitation.
