Will any of this translate to Windows programs like File Manager? Whatever their Image viewer is even called? For some ungodly reason, on my last remaining Windows Device, which is a Surface Book 2 (a Microsoft made laptop!) with very vanilla configurations, everything slows to a crawl in the file manager and if I try to view images on a directory and do the "right arrow" for next or "left arrow" key for previous. It baffles me how something that never had so much slowness can be completely FUBAR'd I miss when Windows had standard apps that were very optimal and didn't slow and ruin my experience. I find myself opening that laptop less and less, and one of these days I might just slap Linux over it.

The photos app also uses webview so yes hopefully

Did you not read the thread? That's literally stated as an explicit goal.
