These changes are only applicable to users in the EEA. For those outside the region, Windows will continue to function as it is!
The changes to Windows for DMA-compliance include:
- You can now uninstall Edge and Bing web search using the built-in settings. Earlier, the option was greyed out.
- Third-party web search application developers can now utilize the Windows search box in the taskbar using the instructions provided by Microsoft and choose any web browser to show results from the web.
- Microsoft will no longer sign-in users to Edge, Bing, and Microsoft Start services during the initial Windows setup experience.
- Data collected about the functioning of non-Microsoft apps, primarily bug detection and its effects on the OS, from Windows PCs will not be used for competitive purposes.
- Microsoft, from now on, will need explicit user consent before combining data from the OS and other sources. It will also deliver new consent screens where required.
A lot of apps do use Edge as an embedded control to display web content. (Back before Edge was a thing, they would do the same thing with Internet Explorer.) Doing this is the path of the least resistance to whoever is developing these pieces of shit, since they can (up until now) expect Edge to be present on the user’s system without having to cart around their own copy of a web browser and keep it updated in perpetuity with all the potential security holes not doing so could bring, yadda yadda yadda. Uninstalling Edge will indeed cause those particular programs to break.
There is now also the “Microsoft Edge WebView2 Runtime Environment” (via) which may or may not be able to run on its own even if the regular user-facing version of Edge is uninstalled – I have no idea, and I haven’t tried.
