desktop.ini customization
About this tag
The desktop.ini customization tag covers Microsoft's June 2026 security updates that intentionally stop File Explorer from honoring folder customizations stored in desktop.ini files when Windows cannot verify the file's origin as trusted. This change affects Windows 10, Windows 11, and supported Windows Server releases, causing custom folder icons and localized display names to disappear. The behavior is not a bug but a security hardening measure that moves a trust boundary into Windows' personalization mechanism. For administrators, this means folders relying on desktop.ini from remote or internet-marked sources may lose their custom appearance. The tag includes discussion of affected updates like KB5094126 and KB5093998.
