OK, my OCD is driving me crazy here. I just installed windows 10 on 2 basically identical computers for my kids(everything is the same except MoBo). I installed the latest version of classic shell on both.
The "start button" shell is different size between the 2 though, here are pictures of each;


I didn't do anything other than install classic shell and select "replace start button". I searched and searched and can not find a setting for the size of the "shell". My guess is it glitched during the install, creating the larger shell (I think the top picture is the way it is "supposed" to be, as it matches the shell size on my computer)
I guess I should consider my life pretty good if this is what I have to worry about, but like I said, my OCD is driving me nuts on this.
Any ideas?
