About this tag
Discussions on WindowsForum.com about desktop.ini security focus on a June 2026 Windows security update that changes how Windows handles desktop.ini files. The update causes custom folder icons and localized display names to stop working if the desktop.ini file's source is not verified as trusted. This is a deliberate security hardening measure, not a cosmetic bug, affecting supported Windows client and server versions. The change breaks familiar shell customization behaviors when files cross trust boundaries, making it a broad-impact issue beyond a niche annoyance.
