Microsoft is experimenting with injecting ads into the Windows 11 start menu experience in an attempt to get us to use more of its products and services.
As Neowin reports, the new ads were first spotted by Twitter user Albacore. The ad appears at the top of the user session flyout, with the two examples found so far advertising OneDrive with a "Back up your files" suggestion, and a "Sign up for a Microsoft Account" suggestion attempting to get you more integrated with Microsoft's services.
For now, this experiment is limited to Windows 11 Dev Channel builds, but it gives you a good idea of where Microsoft hopes to inject ads into the Windows 11 experience in future. You may also remember ads were injected into the Windows 11 file explorer back in March as an experiment.
Whether you like it or not (and I suspect most do not), Microsoft will continue to try and push its other products and services on Windows users. It's also unlikely we'll be offered a way to disable them, much like we can't disable or uninstall the Edge browser anymore.
