Microsoft engineer explains what made Windows 7 take 30 seconds to show the desktop

Changing the desktop wallpaper to a solid color in Windows 7 caused a 30-second delay on the Welcome screen after entering a password. This issue arose because the system waited for a signal from the wallpaper component, which only sent its "I'm ready" signal when an image file was used. When a solid color was selected, this signal was not sent, leading to unnecessary waiting. The problem was acknowledged by Microsoft for both Windows 7 and Windows Server 2008 R2, and it was resolved with a Hotfix update in November 2009. Users found workarounds, such as switching to an image or creating a small solid-color image, to eliminate the delay.

Microsoft admits Windows 11’s emergency update still breaks audio, and a fix may not arrive until October

Windows 11 is facing ongoing challenges with audio functionality following recent updates, particularly with the emergency update KB5129195 released on September 14. This update aimed to fix issues from the September Patch Tuesday update (KB5124008) but has led to new problems, including compromised audio output on some devices and disruptions in secure trust relationships for enterprise systems. Users have reported error messages like “This device cannot start (Code 10)” in Device Manager, and issues with USB audio devices. Microsoft is investigating these audio problems but has not provided a timeline for resolution. Additionally, there are reports of GPU issues on AMD systems, including driver timeouts and black screens, affecting various Radeon models such as RX 6600, RX 7700 XT, RX 7800 XT, RX 7900 GRE, RX 7900 XTX, and RX 9070 XT. Some users found that uninstalling the September update alleviated these problems, but the emergency update KB5129195 does not address the GPU errors.

Microsoft fixes bug behind ‘Defender Antivirus is turned off’ alerts

Microsoft resolved an issue that caused misleading alerts indicating that Defender Antivirus was disabled after recent updates. This fix was confirmed in an update to the Windows release health dashboard and was implemented in the Microsoft Defender Antivirus update (version 4.18.26080.4) rolled out on September 17. The bug, acknowledged by Microsoft in late August, affected users in the Release Preview Channel of the Windows Insider program since at least June and impacted all supported versions of Windows clients and servers. Users received erroneous notifications in the Windows Security app prompting them to activate Microsoft Defender Antivirus, despite it functioning correctly. Misleading alerts could appear upon Windows startup and intermittently thereafter, even when notification settings were disabled.

What Windows 11 KB5129195 fixes

On September 14, 2026, Microsoft released KB5129195, an out-of-band cumulative update for Windows 11 versions 24H2 and 25H2, transitioning systems to build 26100.9457 for 24H2 and 26200.9457 for 25H2. The update addresses several regressions, including failed connections and sign-ins in Remote Desktop Services, host-folder sharing failures in Plan9 file sharing for HCS-managed Linux virtual machines, and failures affecting 8-channel and 3D-audio modes in USB Audio Class 1.0. However, it does not fix ongoing issues with AMD Radeon graphics cards, such as freezes, black screens, and driver timeouts, which have affected various hardware configurations. KB5129195 is available through multiple distribution channels, including Windows Update and WSUS.

30 Days Until Windows 11 24H2 Support Ends; Excel Paste Glitch Surfaces Simultaneously

Microsoft announced on September 14 that the Windows 11 24H2 edition, including Home and Pro versions, has only 30 days of support remaining, with a deadline for updates set for October 13, 2026. Users are encouraged to upgrade to version 25H2 or later to continue receiving security updates. The Enterprise and Education editions will have support until October 12, 2027. Users have reported issues from September's security updates, particularly with the Office patch KB5002914, which disrupts the copy-and-paste function in Excel across multiple versions. Microsoft has acknowledged the issue but has not yet released a fix. A temporary workaround involves manually removing the problematic patch, though this also removes the associated security fixes. Additionally, users have experienced connection drops and unresponsiveness in Remote Desktop Services (RDS) across various Windows versions, including Windows 11 26H1 and Windows Server 2012. Microsoft confirmed that related tools may also stop responding, and restarting virtual machines may temporarily restore functionality. USB audio issues have been reported on certain USB Audio Class 1.0 devices across Windows 11 versions, with users experiencing loss of audio output and corrupted sound settings. Switching to 2-channel mode has helped some users, but Microsoft has not provided a timeline for a comprehensive fix. As Windows Server 2012 nears the end of its Extended Security Updates period on October 13, 2026, the RDS issues add pressure on administrators. Users on 24H2 need to prioritize migration to 25H2, while those with the latest updates should be cautious regarding Excel and Remote Desktop functionalities.

Microsoft rolls out emergency update for Windows 11’s latest patch — recent update causes crashes on AMD graphics, Explorer hang-ups, and broken third-party integrations

Microsoft has released an out-of-band update to address issues from the September 2026 Windows 11 patch, which introduced new features and fixed nearly 1,000 security vulnerabilities. The update includes a movable taskbar, adjustable height, configurable Start menu layouts, enhanced Windows Search, and size indicators in File Explorer. However, users with AMD Radeon GPUs are experiencing crashes due to driver instability, and reinstalling drivers has not resolved the issue. Microsoft did not address these GPU concerns in its communication. The update also fixed instability issues with Remote Desktop Services, but users still report audio output and microphone input failures, which Microsoft has included a fix for in the emergency patch. Lenovo users have reported unexpected black screens or shutdowns linked to power management issues.
