But at least it's a simpler workaround these day.

In the olden days the border width of a window in Windows was 
user-settable, so the only way to get that (and a few other relevant 
settings) was to obtain metrics from the Windows registry.

With Win10, if I read Mark Waddingham's comment correctly, the border 
can only be 1px, so all those old registry calls can safely go away with 
just simple hard-wired arithmetic.
