On 21 August, Windows tester Xeno Panther posted about a Microsoft installer named MicrosoftSettings.exe, and said its job was to move your default search to Bing. The file is still sitting on Microsoft’s download servers, and the company has since answered for it.
The next day, Windows Latest ran the installer on a test machine and published what it does. The app is called Microsoft Recommended Search Settings, the download weighs 22.2 MB, and it reaches nobody through Windows Update or the Microsoft Store. Somebody has to go and fetch it. The first screen arrives with the Bing option already switched to Yes, and the small text under that toggle names Microsoft Edge, Mozilla Firefox and Google Chrome.
In that same test, accepting the toggle installed an extension called Microsoft Bing Homepage & Search into both Chrome and Brave. Brave is not named on the setup screen, but it is built on Chromium and takes the same extension Chrome does. Chrome’s permission prompt for it asks to read and change data on all websites, display notifications, and change the home page, start page and search settings to bing.com. Setup then ends by opening a Microsoft Rewards page in Edge, and the new tab page in the changed browser becomes Bing’s MSN feed.
Chrome pushed back on the spot. It offered to put Google Search back, and Microsoft’s extension answered with a second box placed directly under Chrome’s button, telling the user not to change it back and warning that reverting costs access to Bing search and its wallpapers.
One detail is still in dispute. Part of the coverage has reported that Edge is left out because it already runs Bing, while the installer’s own wording lists Edge alongside Firefox and Chrome. Until Microsoft publishes documentation, the reliable reading is the three browsers printed on the setup screen, plus Chromium relatives like Brave.
On 26 August, Microsoft answered. In a statement to the outlet that ran the test, the company said the app is optional, that users choose to download and install it, that it is not distributed through Windows or Edge, that any change to default settings requires consent, and that those settings can be adjusted again at any time.
So, should you run it? Only if you want Bing, its homepage and the Rewards offer, in which case a browser’s own settings page gets you there without granting an extension permission to read every site you visit. If you have never run the file, nothing on your machine has changed and there is nothing to update or patch.
If you already ran it, put your browser back
A full browser reset is not required for this, and neither is reinstalling. The extension made the change, so removing it and correcting the search setting is enough. If you would rather start clean on a different browser, there are pages for Firefox and Brave in our library.
What to watch is distribution. Microsoft has not said where this app will eventually be listed for people to find, or whether it stays a standalone download that only turns up when somebody goes looking. That is the line worth watching: the day it reaches people who were not looking for it, an optional app becomes something else.
