Microsoft has deprecated a series of web components in Windows, including Legacy Web View, HTML and JavaScript apps from Windows 8 and 8.1, the first generation of Progressive Web Apps, and developer tools from the original Edge browser. These components are built on EdgeHTML, which powered the classic Edge before its transition to Chromium in 2020. While these features will not be removed immediately and will continue to receive security updates for now, they will eventually cease to receive updates and be phased out in future Windows versions. Microsoft is directing developers towards alternatives like WebView2 and modern Chromium-based Progressive Web Apps. This announcement is part of a broader clean-up initiative that also includes the removal of WordPad, Mixed Reality, NTLMv1 protocols, and tools like WMIC and PowerShell 2.0.
