## What it is
A Windows shell extension (DLL) that adds background blur, Acrylic, or Mica effects to File Explorer on Windows 10 and Windows 11. It supports custom blend colors, light/dark mode adaptation, and is compatible with other Explorer customization tools.

## Use cases
- add blur effect to windows file explorer background
- apply mica effect to explorer on windows 11
- make file explorer background acrylic on windows 10
- customize explorer window transparency and blend color
- make explorer match dark mode with blur background

## When to choose
- you want blur/acrylic/mica effects specifically in File Explorer on Windows 10 or 11
- you use third-party themes or tools like StartAllBack and need a compatible effect mod
- you want light/dark adaptive transparency with custom colors

## When to avoid
- you want the effect applied system-wide to all windows (use DWMBlurGlass instead)
- you are not on Windows 10 or 11
- you are unwilling to register a DLL with administrator privileges
