Internet Explorer Can Still Take Over a Fully Patched Windows PC in 2026
Internet Explorer can still take over a fully patched Windows machine, years after Microsoft retired it in 2022. The code that ran it was never removed from Windows, and a researcher just turned it into working remote code execution.
The researcher behind it, Igor Sak-Sakovskiy, published the work with Microsoft’s permission. The piece he pulled apart is called the WebBrowser control, the same code that drew web pages in Internet Explorer for decades. It still runs inside programs written in Visual Basic, .NET and C#, the kind of older business software and legacy tools that quietly kept the component alive. One detail makes it stranger. No official Microsoft document says this component is retired or about to be. People treat it as gone, while it keeps running underneath.
