Microsoft has blocked EdgeDeflector, a third-party app that allowed Windows 11 users to bypass Edge and use their default browser for Start menu search results. This move is seen as an attempt to force users into using Edge, despite Microsoft's claims that Windows offers an open platform for various web browsers. The block is part of an upcoming Windows 11 update and has been met with criticism from developers and users. Microsoft's actions have raised concerns about the company's prioritization of its own products over user choice.
