Endpoint/Device Security Windows security warnings for RDP files may display incorrectly April 29, 2026 Share By SC Staff As reported by Bleeping Computer, Microsoft has confirmed a new issue affecting Windows security warnings that appear when opening Remote Desktop (.rdp) files. This problem impacts all supported versions of Windows, including Windows 11, Windows 10, and Windows Server. The security warning dialogs, intended to protect users from malicious RDP files, are not displaying correctly on affected systems. Text within the warning windows may be unreadable, and buttons can be misplaced, hindering user interaction. This issue is reported to occur on systems with multiple monitors that have different display scaling settings. Microsoft introduced these warnings in the April 2026 cumulative updates to combat the increasing abuse of RDP files by threat actors in phishing campaigns. These files are commonly used in enterprise environments and have been exploited by groups like APT29 to steal credentials and data. The incorrect display of these crucial security prompts could potentially leave users vulnerable if they cannot properly interact with or understand the warnings before establishing a remote connection.
