Microsoft announces Windows changes in response to the EU's DMA for EEA users, including Edge not prompting users to set it as the default browser unless opened
Apparently only the Digital Markets Act can stop Bing from begging you to switch . … Microsoft's changes in response …
Context & Ripple Effects
Microsoft has previously used Windows to steer users toward Edge, including a move to block tools that redirected Start-menu search links away from Edge and tests that opened some Mail links in Edge even when another browser was the default.
The company had already outlined EEA-specific Windows DMA changes, including the ability to remove Edge and alter search options, in its earlier Windows 11 compliance plan. The new prompt restriction narrows another point at which Windows can favor Microsoft's browser.
First-order effects
- EEA Windows users will no longer face a default-browser prompt from Edge unless they open Edge, reducing an OS-level nudge toward Microsoft's browser.
- Microsoft must maintain a more limited Edge onboarding flow in the EEA, despite Edge and Bing having been tentatively viewed as insufficiently dominant for DMA designation in earlier EU reporting.
Second-order effects
- Rival browsers gain a cleaner path to retain users' existing default choices in the EEA, while Microsoft has less opportunity to convert users through Windows prompts.
- The change adds another regional variation to Windows behavior, increasing the value of compliance-specific product controls for platform software.
Third-order effects
- If such changes persist, European platform rules will increasingly shape default settings, uninstallability, and user-choice flows as competitive infrastructure rather than minor interface details.
- The broader test is whether regulators treat self-preferencing across an operating system's connected services as a recurring platform-design issue, even where individual services are not dominant on their own.
The trend: The DMA is pushing operating-system vendors to replace built-in service promotion with more neutral, region-specific choice mechanisms.
