Re: Windows high contrast mode.

For what it's worth, there's been long-standing (and unresolved) 
discussions around whether or not WHCM (now Windows Contrast Themes) is 
or isn't covered by WCAG, as how it actually works/what it does is not 
consistent or documented, and taking a step back counts as the user 
changing the presentation (in ways that authors can't necessarily 
predict or control in most cases). One of the earliest discussions I can 
surface at the moment is here https://github.com/w3c/wcag/issues/623
