Microsoft Defender mistakenly flagged legitimate DigiCert root certificates as Trojan:Win32/Cerdigent.A!dha, leading to their removal from Windows systems globally. This issue arose after a Defender signature update on April 30th, with affected certificates including 0563B8630D62D75ABBC8AB1E4BDFB5A899B24D43 and DDFB16CD4931C973A2037D3FC83A4D7D775D05E4. The certificates were removed from the AuthRoot store under the Registry key HKLMSOFTWAREMicrosoftSystemCertificatesAuthRootCertificates. Microsoft has addressed the issue in Security Intelligence update version 1.449.430.0, which also restored the removed certificates. The false positives were linked to detections related to a recent DigiCert breach, where threat actors obtained valid code-signing certificates used for signing malware. DigiCert revoked 60 code-signing certificates, including those linked to the "Zhong Stealer" malware campaign. The malware utilized certificates issued to companies like Lenovo and Kingston, but the certificates flagged by Microsoft Defender are root certificates and do not correspond to the revoked code-signing certificates.

Microsoft is replacing the legacy File Explorer Properties dialog box in Windows 11 with a modern version powered by WinUI 3. This change aims to improve the performance and reliability of Windows 11. The current Properties dialog does not support dark mode, which has been an issue for users. Recent findings from Windows 11 Insider builds indicate that Microsoft is actively developing a new file properties dialog. Strings for “DeletedFileProperties” have been discovered, suggesting the old dialog will be replaced. Microsoft is also modernizing outdated Windows 8 UI elements within Windows 11. The introduction of the WinUI 3 properties dialog is expected to enhance File Explorer's performance by streamlining its hybrid codebase. Users can anticipate gradual updates throughout 2026, with a rollout to the Experimental channel expected later this year.

Microsoft resolved an issue affecting the display of security warnings when opening Remote Desktop (.rdp) files across all supported Windows versions, including Windows 11, Windows 10, and Windows Server. This problem was particularly evident on devices with multiple monitors having different display scaling settings. The fix was included in the optional KB5083631 preview cumulative update for Windows 11. The issue arose after the installation of the April 2026 security update, which introduced security warnings to enhance protection against phishing attacks. Users reported misalignment and obscured buttons in the security dialog, making it difficult to interact with. Additionally, the April security updates caused issues with third-party backup applications on Windows 11 systems and led to restart loops and failures during update installations on Windows Server.
