Microsoft has developed a dedicated executable, named MicrosoftSettings.exe, whose sole purpose is to set Bing as the default search engine across all installed browsers, including Chrome, Firefox, and Brave. The application is not distributed via Windows Update nor available in the Microsoft Store; instead, it can be downloaded as a standalone file from the company's official servers. Its operation relies on a WinUI shell with WebView2 that, during installation, prompts the addition of extensions to browsers to force the homepage and results on Bing, concluding the process with an automatic redirect to the Microsoft Rewards page.

An application engineered for a single function

The executable, weighing 22.2 MB, requires the installation of an extension named "Microsoft Bing Homepage & Search" which, according to Chrome's warnings, can read and modify all data on any website. Microsoft's choice to build a dedicated application for this purpose appears disproportionate compared to available alternatives, especially considering the company is already managing a series of WebView2 components known for their high resource consumption. For instance, the default Weather app on Windows 11 consumes over 1 GB of RAM, a figure that highlights the criticality of resources on entry-level PCs.

The conflict between Chrome and Microsoft in the user's browser

During testing, Google reacted immediately to Bing's imposition: after installing the extension, Chrome displayed a prompt asking the user if they wished to return to Google Search. Microsoft responded with a second dialog box warning of losing access to Bing and its features if the change were revoked. This "duel" of prompts within the browser is not a new phenomenon: as early as 2024, Microsoft had used similar tactics to prevent the return to Google, confirming a persistent strategy of user acquisition through direct pressure.

A strategy in contrast with cleanup promises

The introduction of this tool clashes with Microsoft's public efforts to reduce "clutter" on Windows 11. Recently, the company cleaned up the search bar from ads and sponsored content, removing MSN tiles and prioritizing local results. However, while on one hand invasive elements are removed from the operating system, new channels are being built to push Bing inside third-party browsers. This duality suggests that the primary goal is not user experience quality, but reaching market share for Bing, which recently crossed the one billion monthly users threshold according to Satya Nadella.
