The latest Windows 11 preview feature is a Bing and Edge exclusive search box on your desktop

pcgamer.com:

Windows 11 preview updates have been bringing plenty of new features to test on the platform. Some are great like HDR sliders, and others not so much, like when it recently broke some Microsoft Store apps. But that's what preview updates are for, allowing Microsoft to test out ideas to see what works and what doesn't in front of a small batch of consumers. The current insider build holds one such feature, which many users are hoping doesn't make it to the official release.

According to The Register, Microsoft has kindly added a search box widget to the Windows 11 desktop in the Dev Channel of the 25120 update. When typed in, this box will produce a variety of drop down options, powered by Microsoft's Bing search engine and shown in Microsoft Edge. It will also ignore default browser settings, so even if those have been updated this search bar still defaults to Microsoft's programs. 

The Windows insider blog states «We are excited to learn your feedback on this interaction model, so please use the Feedback Hub to provide feedback if you receive this experiment.» They'll definitely get feedback. Many users aren't going to like having Bing and Edge once again shoved in their faces, especially right on their very own desktops.

Thankfully the feature can be turned off fairly easily, but in this iteration seems to be on by default. It is also just a preview build feature being tested, so hopefully it won't actually release, especially with the understandable backlash from some testers. Though it's only a limited number of insiders who've had the pleasure of experiencing the search bar, it's already a pretty unpopular move, fairly copping ire on Twitter.
