Microsoft is currently in the process of rolling out update KB5060533, a new patch for Windows 10 that includes the latest security fixes—as well as a small tweak that was snuck in with everything else.
It turns out that Microsoft has added links to the Windows 10 Calendar to recognize special themed days, such as World Environment Day (June 5, 2025), World Oceans Day (June 8), Juneteenth National Freedom Day (June 19) and American Eagle Day (June 20).
When you click on one of those themed days, Windows launches the Edge browser and performs a Bing search of the event—and Bing is used even if your default search engine is something else.
According to Windows Latest, there’s no setting to turn off this feature, nor is it possible to change which search engine is used. The purpose of the feature, according to Microsoft, is to offer a new “rich experience.”
