Microsoft fixes Remote Desktop warnings displaying incorrectly

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.

I investigated Windows 11’s massive 5GB monthly .msu updates. AI is only part of the problem.

Windows 11 updates have significantly increased in size, with monthly cumulative updates often exceeding 4GB and some approaching 5GB. One update can expand to nearly 9GB when extracted. Microsoft has shifted to delivering Latest Cumulative Updates (LCUs), which include all previous fixes, leading to larger update sizes over time. The introduction of Checkpoint Cumulative Updates aims to reduce this growth by establishing periodic baselines, but the effectiveness has been mixed. The May 2025 cumulative update saw a size increase from approximately 6.5GB to nearly 9GB, with new MSIX files related to semantic search and on-device AI contributing to this growth. Windows Update uses applicability logic to minimize download sizes for users, but enterprises must download full packages, resulting in increased storage costs. The average yearly storage cost for enterprises rose from about 11 GB in 2024 to 52 GB by 2026. Users can check their actual download sizes through the Windows Update settings and Event Viewer logs.

Microsoft: New Remote Desktop warnings may display incorrectly

Microsoft has identified an issue affecting the display of security warnings when users open Remote Desktop (.rdp) files across all supported versions of Windows, including Windows 11, Windows 10, and Windows Server. The security warning may not render correctly, making the text difficult to read and buttons misaligned, especially when multiple monitors with different display scaling settings are used. This issue often results in overlapping text or obscured buttons in the warning window. The problem is part of Microsoft's security enhancements introduced with the April 2026 cumulative updates, which aim to mitigate risks associated with malicious RDP connection files. Users receive a one-time educational prompt upon opening an RDP file for the first time, followed by a security dialog that provides information about the file's publisher and resource redirections. RDP files are commonly used in enterprise environments, but their exploitation in phishing campaigns has raised security concerns, particularly by groups like the Russian state-sponsored APT29.

Microsoft Says You Don’t Need A Third-Party Antivirus App Anymore

Microsoft Defender Antivirus effectively addresses everyday security risks for many Windows 11 users without the need for additional software. It is active by default, integrated into the OS, and continuously updated. Windows 11 includes various security features, such as Microsoft Defender SmartScreen, Smart App Control, and Controlled Folder Access, which protect against unsafe links, untrusted applications, and unauthorized data modifications. Microsoft Defender scans files upon access and monitors system processes for threats, utilizing cloud capabilities to address emerging risks. While many users find Microsoft Defender adequate, experts note it may not meet everyone's needs, particularly in enterprise environments. Reviews have pointed out shortcomings, such as low phishing detection and inadequate ransomware protection, with a protection accuracy rating of 93 percent compared to some paid alternatives that achieved 100 percent.

Microsoft quietly reveals whether you need a third-party antivirus software in Windows 11

Microsoft has stated that third-party antivirus software is not necessary for Windows 11, as its built-in antivirus solution, Windows Defender, is sufficient for most users. This assertion was made public on April 9, when Microsoft declared Windows 11 the most secure version of its operating system. Windows Defender is effective when users regularly install Security Intelligence Updates, apply monthly Patch Tuesday updates, and activate SmartScreen for filtering harmful downloads. While third-party antivirus solutions may be beneficial in certain scenarios, such as enterprise environments or for users seeking additional features, Microsoft advises relying on a single real-time antivirus solution, which is typically Windows Defender. Microsoft Defender is a comprehensive protection stack that includes real-time scanning, cloud-delivered protection, and automatic updates. Independent tests have shown that Microsoft Defender achieves high protection rates, comparable to leading paid antivirus solutions. The built-in Windows Security application includes features like SmartScreen, Smart App Control, and ransomware protection, providing extensive coverage without additional costs. The consensus is that most users will not need third-party antivirus software in 2026, as Windows Security offers robust protection against modern threats.

Microsoft April Update Forces BitLocker Recovery on Servers

A recent Microsoft security update, April 2026 KB5082063, has caused issues for administrators of Windows Server 2025 and Windows 11 systems, with many devices entering BitLocker recovery mode after reboot, requiring a 48-digit recovery key. This issue primarily affects enterprise-managed systems with specific TPM Group Policy settings involving PCR7 validation. Similar problems have been reported with updates KB5083769 and KB5082052 on Windows 11. The issue arises from five conditions: BitLocker must be enabled on the OS drive, the Group Policy must include PCR7, the msinfo32.exe tool must show Secure Boot State PCR7 Binding as “Not Possible,” the Windows UEFI CA 2023 certificate must be in the Secure Boot Signature Database, and the device must not be using the 2023-signed Windows Boot Manager. Microsoft suggests two workarounds: removing the TPM validation Group Policy before the update and re-enabling BitLocker, or applying a Known Issue Rollback (KIR) before installation. Skipping the April updates is not advisable due to the addressing of 167 vulnerabilities, including two zero-days. BitLocker recovery issues following updates have been recurring since 2022, with similar incidents reported in August 2022, August 2024, and May 2025, indicating ongoing challenges with Secure Boot certificates and TPM validation bindings in enterprise environments.
