Microsoft has started testing promotion for some of its products in the file explorer app. A user discovered the new Windows 11 feature. Microsoft will use these advertisements to promote other Microsoft products based on the screenshot shared.
This is not the first time Microsoft added promotional messages to File Explorer, as in 2016, Microsoft also showed a OneDrive ad in the Windows application. This can be explained by the company running an A/B testing experiment trying to gauge the success of such a feature or by the company disabling it after the visible user outcry.
The company broke the Windows Start Menu and Taskbar when testing a Microsoft Teams promotion on Insiders, so some of these experiments had unforeseen repercussions. Jen Gentleman, Microsoft software engineer clarified that right-click performance had been juiced up. Windows 11 tester noticed that the context menu felt faster with the latest preview build; Gentleman said they did some work with 22572 to improve the context menu performance.
