In the June 2026 Security Update for Windows 11 and Windows 10, Microsoft implemented a change that prevents custom folder icons and localized folder names from appearing if derived from an untrusted "desktop.ini" file. Users may initially perceive this as a bug, as folders may revert to default settings without user intervention. To maintain customizations, organizations should add trusted sources to the "Trusted Sites" list via Control Panel. Businesses can enable the "Allow the use of remote paths in file shortcut icons" policy through the Group Policy Editor, although this may reduce security. Users can also remove the Mark-of-the-Web tag from trusted "desktop.ini" files using PowerShell commands. This update reflects a broader trend of prioritizing security over customization in the operating system.
