I know you can change the color of the outline, but I'm not certain about a way to change the thickness.
The color can be changed from Settings > Personalization > Color > Accent Color.

When using Alt+Tab is there any way to make the "selected window" line, a bit bolder or noticeable? its hard to see which one is the selected one.

I used a bright yellow color, but depending on your preferences or wallpaper picture, you might prefer something else, like red, blue, or something else entirely.

Has anyone else's experience with Windows 11 been complete garbage? There's not 1 new feature that I like and they've ruined a lot of stuff and made it either impossible or a pain to revert it, like the start menu. Wish I didn't delete my old Windows 10 install.
