No, I’m not. Chromium doesn’t exist in Windows unless you install a program that includes it. Chromium web engine is “native” to the chromium web browser, not to any OS (except maybe ChromeOS). As espi mentioned, Internet explorer’s mshtml is the only engine “native” to Windows. Just look at the Opera browser, they changed web engines from Presto to chromium; that’s not using “what’s native to the platform” (Opera works across all OS’s with chromium, except for iOS for the restriction I mentioned before), it’s using what the developers/company want to use to render their pages. Nothing in Windows itself provides any of the chromium engine “pieces”
