Microsoft has released an update for Windows 10 and Windows 11 that blocks workarounds used by browsers like Firefox to intercept 'microsoft-edge://' links, forcing them to open in the default Edge browser instead. This move has been seen as anticompetitive behavior by Microsoft, limiting user choice and promoting its own browser. The update affects links used by certain Windows features, such as Bing search from the start menu. A new tool, MSEdgeRedirect, has been developed to bypass this restriction, but it requires running in the background and is flagged by Microsoft's SmartScreen.
