Dwelling home windows 11’s native apps like File Explorer and completely different shell apps use rounded corners and Fluent Design parts like Acrylic by default. Together with rounded corners, one different important design operate of Dwelling home windows 11 is provides like Mica which aligns the background shade of apps with the desktop.
Mica is rather like Acrylic, however it really works in a barely utterly completely different technique. As Microsoft describes, Dwelling home windows Mica supplies creates a “colour hierarchy” by aligning the background with the equipment, in a bid to distinguish between quite a few open circumstances of the app like File Explorer, and so forth.

For the time being, builders can’t permit this new supplies of their Win32 apps. Nonetheless, that’s set to range shortly. Starting with Dwelling home windows 11 mannequin 22H2, builders can merely permit Mica or Acrylic inside the container/window of their typical Win32 apps i.e desktop functions.

- DWMSBT_NONE: Builders can skip Mica or Acrylic within the occasion that they’ve their personalized design for the app window. As an example, Spotify comes with its private header. When this value is about, Microsoft obtained’t don’t draw any system backdrop.
- DWMSBT_MAINWINDOW: Applies the backdrop supplies impression equal to a long-lived window.
- DWMSBT_TRANSIENTWINDOW: Applies the backdrop supplies impression equal to a transient window.

In precise truth, there’s a third-party open-source instrument known as “Mica for Everyone” which makes use of DwmSetWindowAttribute and completely different methods to energy permit Mica in any app.
Whereas this exchange seems like a bit of wonderful info for everyone, there’s a catch. Microsoft says the model new variable is exclusive to Dwelling home windows 11 22H2 (Assemble 22621). In several phrases, if builders are concentrating on prior variations of the OS, they’re caught with the earlier design.
