Why Windows 11 24H2 displaying mixed languages

I’m experiencing the exact same issue on my Windows 11 system after updating to the 24H2 build. I tried switching my system language from Portuguese to English, and despite removing Portuguese entirely and keeping only English installed, I’m still seeing a frustrating mix of both languages across the interface. It’s reassuring (and a little maddening) to know I’m not alone in this—your description matches my situation perfectly. I also came across that same report you linked, and it’s clear this is a widespread glitch tied to the 24H2 update.

Have you found any workarounds that actually stick, or are we all just waiting for Microsoft to sort this out?
