Microsoft Investigates Multiple Issues in Classic Outlook
Microsoft is investigating multiple issues affecting the classic Outlook desktop email client, including a bug that causes the mouse pointer to disappear, making the app unusable. Additionally, Microsoft is addressing email synchronization and connection problems, such as "Can't connect to the server" errors when creating groups and sync issues with Gmail and Yahoo accounts. The company has acknowledged these problems and provided temporary workarounds while continuing their investigation.
Microsoft Family Safety Bug Blocking Google Chrome and Other Browsers Fixed
Microsoft has resolved a bug in its Family Safety service that was preventing Google Chrome and other web browsers from launching on Windows 10 and Windows 11 systems. The issue, acknowledged in June 2025, caused browsers to crash or fail to launch due to a problem with the web filtering tool. The bug affected devices running Windows 10 22H2 and Windows 11 22H2 or later. Microsoft deployed a service-side fix in early February 2026 to address the problem.
Microsoft October 2025 Updates Disable USB Input in Windows Recovery Environment
Microsoft's October 2025 security updates (KB5066835) initially disabled USB mice and keyboards in the Windows Recovery Environment (WinRE), affecting both client (Windows 11 24H2 and 25H2) and server (Windows Server 2025) platforms. This issue made WinRE unusable for troubleshooting or repairing the OS, prompting users to switch to Bluetooth or PS/2 input devices as a workaround. Microsoft has since released an emergency update (KB5070773) to resolve the issue, which started rolling out on October 21, 2025. This update restores USB functionality in WinRE, allowing users to navigate recovery options. Affected customers can also use touchscreen, PS/2 devices, or USB recovery drives as workarounds. OEMs and enterprises can use PXE in Configuration Manager to install the update, while IT administrators can deploy push-button reset features using Windows ADK and WinPE add-on. Additionally, Microsoft confirmed in February 2026 that the October 2025 KB5068164 update for Windows 10 also broke WinRE. A new update (KB5075039) was released to fix this issue, requiring the WinRE partition to be at least 256MB in size.
Active Directory Sync Issues in Windows Server 2025
Microsoft has released a fix for Active Directory synchronization issues affecting Windows Server 2025 systems. The problem occurs after installing security updates released since September 2025. It impacts synchronization for large Active Directory security groups exceeding 10,000 members, particularly when using Microsoft Entra Connect Sync. The issue affects applications relying on the Active Directory directory synchronization (DirSync) control. Microsoft has provided a Known Issue Rollback (KIR) Group Policy for managed devices and a registry key workaround for non-managed devices and home users. A separate bug causing Windows update failures on Windows 11 24H2 and Windows Server 2025 devices is also being addressed. Guidance has been issued for smart card authentication issues across all supported Windows versions.
Windows 11 updates disrupt localhost HTTP/2 connections
Microsoft's October Windows 11 updates (KB5066835) and September's KB5065789 preview update have caused issues with localhost (127.0.0.1) HTTP/2 connections. Users are experiencing errors such as 'ERR_CONNECTION_RESET' or 'ERR_HTTP2_PROTOCOL_ERROR' when attempting to connect to localhost. This affects various applications, including Visual Studio debugging, SSMS Entra ID authentication, and the Duo Desktop app. The issue also affects Windows Server 2025 systems and is linked to a bug in the HTTP.sys Windows-based web server for ASP.NET Core. Microsoft has provided a temporary fix via Known Issue Rollback (KIR) for non-managed business devices and most home users. IT administrators can resolve the issue on managed devices by installing and configuring a specific KIR group policy. A permanent fix will be included in a future Windows update.
