Summary

Hide ▲

Microsoft released the optional KB5083631 preview cumulative update for Windows 11, fixing a Remote Desktop (.rdp) security-warning rendering bug that could make the dialog unreadable on multi-monitor systems with mixed scaling. The issue also affected supported Windows 10 and Windows Server builds, and it could surface after the April 2026 (KB5083769) security update. The fix matters because the warning was introduced to reduce phishing abuse of RDP files, and a broken dialog can block users from seeing or acting on the prompt.
