Hello,
Yes, please change your username to something else. As for your question, you can use this guide to backup your Fences layout snapshot. It should work in your Windows 11 system as long as all the shortcut links point to the same location on your new Windows 11 system. And those shortcuts/icons also on your Windows 11 desktop.
