Installer VS MicaForEveryone

Looks like it's open source: https://github.com/Rectify11/Installer

Says so on the FAQs page of the (terrible) website as well.

They apparently don't have an uninstaller yet. It seems like your options come down to either System Restore, or completely reinstalling Windows 11. This is a good example of why it's important to be careful with system modifications like this.

Just an example of the current aero.msstyles being broken thanks to Microsoft: https://github.com/MishaTy/Rectify11Installer/issues/131

2)Install Rectify 11 to make everything in Windows 11 dark except title bars (Its open source program that still under development, but works well for me); installation process is quiet simple.

Rectify 11 Default Wallpaper. Im sure you can find it in the source code or sum

Install Rectify11 at https://github.com/MishaTY/Rectify11Installer/releases/tag/v-3.0-rp (it's a system patcher)

Download MicaForEveryone

There's no system setting, but you could try this: https://github.com/MicaForEveryone/MicaForEveryone

3)Install MicaForEveryone its a solution to make title bars dark (but it can do more)

Tools used | StartAllBack, OldNewExplorer, - MicaForEveryone, TClock Redux

You can do a fair bit with Stardock WindowFX and Mica for Everyone

Probably using MicaForEveryone.

I used an app called "MicaForEveryone", it's a title bar backdrop utility to change its title bar style with options like Acrylic, Mica, and Tabbed. It works on Windows 11 22H2, you should try that. https://github.com/MicaForEveryone/MicaForEveryone

Are you sure?, I took the image here, and as you can see user x-0D is using Windows 11 in the dev channel, and created the same issue in the Rectify11 repository. Maybe some previous build of rectify had this feature.
