Not trying to be rude to you, but you probably should have submitted a completely new question instead of posting your question in with my question, have you already thoroughly looked in all of the settings area, especially here:

Are you looking to increase or reduce the spacing?

I'd like to increase the spacing between the icons if possible. Thank You

Hello,
Sorry to hear you are having issues. But, why did you post multiple threads asking the same question?

Thank you.

It is possible to adjust things a little using a registry key.

HKEY_CURRENT_USER\SOFTWARE\Stardock\Start8\Start8.ini\Start8

Create a String value called TaskbarPadding and give it a number in pixels and it will increase the padding between the taskbar buttons.  You will need to sign out afterwards to see the change.

Neil,

Thanks so much for your informative reply, I followed your instructions and now I'm pleased to report that I've got the taskbar icon spacing that I was trying to achieve. I'm being going into the windows registry for various reasons for quite a long time due to the fact that I'm old and have been using various editions of the windows operating system. In the back of my mind I knew there must be a method to achieve what I wanted with my windows 11 taskbar icons.
