I have a weird problem.  I did something stupid that caused me to have to un-install and re-install the latest Aero Glass.  However, after I did, I notice my windows have no borders.  Is this normal?  Is there a way to get my classic Windows-7 style Aero glass borders back?

Attached is a screenshot.

I'm having almost the exact opposite issue. My windows got borders when I clicked "Revert" to undo some settings I was experimenting with but I can't for the life of me find how to change the settings for the borders.

That's how mine looks.  It's not that there isn't a border, it's that the border is extremely thin.

Maybe try changing the window border thickness? See here: https://winaero.com/blog/how-to-reduce-window-border-size-in-windows-8-windows-7-and-windows-vista/ (it also works on Win10)
