🔐 Just shipped a fix for the April 2026 Windows update (KB5083769) that flags unsigned RDP files as "Unknown Publisher".
If you manage RDP shortcuts via Intune and your users are suddenly seeing red security warnings — here's a complete solution:
✅ Self-signed code signing cert (no PKI required)
✅ rdpsign.exe signing workflow
✅ Intune Win32 package (install + uninstall scripts)
✅ Trusted Certificate profile + Settings Catalog policies
✅ Versioned detection rule for clean updates
✅ Supersedence pattern for migrating from unsigned deployments
Tested in production on a real M365 Business Premium environment.
