Microsoft warns of phantom Defender-off notices after Defender updates

Microsoft says Windows Security may display false ‘Defender is off’ alerts after Defender antivirus updates, even though Defender remains active. The issue affects all supported Windows client and server versions, including Windows 11 26H1 and Windows Server 2025, and can appear at startup or intermittently. A fix will be released in a future Defender Antivirus update, with Microsoft noting similar post-update alert bugs have occurred previously.

Windows 11 August update disrupts cursors and wallpapers; delay installation

The August optional Windows 11 update KB5120998 introduces the movable taskbar, a resizable Start menu, and other features but is reportedly breaking custom cursor styling and wallpaper settings for many users, with some also seeing pixelated text and DISM repair errors. Microsoft hasn’t publicly acknowledged these as known issues; the advised workaround is to uninstall the update, and a broader fix is expected with the September Patch Tuesday rollout, so users should skip installing it for now.

Microsoft's October 2025 Windows 11 Update Causes Critical Recovery and Localhost Failures

Microsoft has confirmed that the October 2025 update for Windows 11 (KB5066835) causes a bug that disables mouse and keyboard functionality in the Windows Recovery Environment (WinRE), making it unusable. The issue affects navigation within WinRE, although USB devices still work within the main OS. Microsoft is investigating and plans to release an out-of-band update to fix the problem. As a temporary workaround, users can revert to an older version of the WinRE image or uninstall the problematic update.

Microsoft Addresses Critical Windows 11 and 10 Update Issues Causing System and SSD Failures

Microsoft confirmed that the August 2025 security update (KB5063878) causes severe lag and performance issues in Windows 11 and Windows 10, particularly affecting NDI streaming applications. The problem stems from interference with the RUDP protocol, leading users to recommend switching NDI's transport mode to TCP or UDP as a temporary workaround. Microsoft is investigating a permanent fix, but until then, affected users should consider delaying the update or applying the workaround to prevent disruptions.
