Windows 10: Shrink window caption buttons w/o shrinking taskbar tray icons?

I found this tutorial on how to shrink the window caption buttons (minimize/maximize/close) by tweaking the registry. However, as anyone who uses it is aware, changing the caption button sizes also changes the taskbar tray icons, so by shrinking the caption buttons to a more sensible size you end up with tiny taskbar icons. Does anyone know of a way to shrink the caption buttons without also shrinking the taskbar icons?

Address toolbar not shrinking with taskbar

Hello,

When I use the small taskbar buttons, the address toolbar does not shrink with the taskbar causing a gap between the icons and the bottom of the screen. Is there anyway to fix this? I have tried restarting windows explorer and that doesn't work, neither
does a restart or anything like that. Any help is appreciated.

 

Some icons shrink

I've had this problem for years and just haven't bothered to ask why but I really would like an answer. Icons of the same size, same folder made by same program will be on my desktop then a couple of them will shrink. Never all of them. I have to change
the icon then it's okay. Then after a day or so a different icon will shrink. This has happened on every version of windows in the last 10 years.

 

Shrinking a volume

Thanks, Stefano. At your suggestion I did a Defragmentation on the drive I want to shrink. That took almost a day on a 1 TB drive. The drive is now 0% fragmented. But still I'm getting "wrong perameter" when I try to shrink the volume. Here's a screenshot
of the dialog window for shrinking the drive:

The amount of space I last put in to shrink was 50012. Any idea why that didn't work?
