Microsoft is once again harassing Google Chrome users on Windows 10 and Windows 11 with popup desktop advertisements promoting Bing and its GPT-4 Bing Chat platform.
The unsolicited ads are believed to be shown when users have Google Chrome open and configured to use Google as the default search engine.
The ad then says that clicking "Yes" will change your default Google Chrome search engine to Bing and install the Bing Service.
"Wait-don't change it back! If you do, you'll turn off Microsoft Bing Search for Chrome and lose access to Bing Search and wallpapers," reads the Bing extension's plea.
This is not the first time Microsoft has targeted Google with popup desktop ads, previously using a similar one in July 2023 to promote Bing Chat.
In 2020, Google and Microsoft targeted each other with ads promoting their own browsers, with further ads shown in 2021.
