Microsoft Confirms October Windows Updates Can Break Exchange Server Email Services

Microsoft has acknowledged that the Windows Server security updates released on October 13, 2026, may disrupt Exchange Server email services, affecting on-premises systems running Exchange Server 2016, 2019, and the Subscription Edition. The disruptions can include blocked webmail access and undelivered messages. Microsoft has identified four specific Windows updates linked to these issues: KB5126646 for Windows Server 2025, KB5126655 for Windows Server 2022, KB5126651 for Windows Server 2019, and KB5126868 for Windows Server 2016. Symptoms may include inability to log into Outlook on the web, messages stuck in the Outbox, increased mail queues, and failed mailbox access. A critical error to monitor is MapiExceptionMdbOffline, and affected systems may log Event ID 1006. The October updates introduced a default limit of 512 simultaneous Endpoint Lookup calls, which can be exceeded under heavy Exchange workloads. Microsoft has provided a registry workaround to increase this limit and suggests monitoring for recurring failures. The disruption coincides with the end of the final paid update period for Exchange 2016 and 2019, with future updates limited to the Subscription Edition.

How to optimize your Windows PC for excellent performance

Personal computers have improved in speed and performance due to advancements in hardware and software, but performance can still vary based on configurations and usage. The latest version of Windows may experience occasional lags even with high-end hardware. To optimize Windows PCs, users should ensure they have the latest updates installed, as these enhance performance and security. Regularly updating drivers and applications is also important. Freeing up disk space is crucial for optimal performance, as a cluttered hard drive can slow down the system. Users should monitor their disk space and delete unnecessary files. Malware can hinder performance, so running antivirus scans is essential if issues arise. Adjusting power settings to "Best Performance" can improve speed, particularly when the device is plugged in. Pausing OneDrive syncing can alleviate resource consumption during uploads. Upgrading to a solid-state drive (SSD) can significantly enhance performance, as SSDs offer faster boot times and application loading. Increasing RAM capacity allows for better handling of simultaneous processes. Disabling unnecessary startup programs can free up system resources, and adjusting Windows appearance settings can conserve RAM. Uninstalling unused applications can also improve performance. For gamers, enabling Game Mode prioritizes system resources for gaming. Regularly restarting the PC helps maintain optimal performance by closing background processes and refreshing memory.
Windows RAM at 91%? Use RAMMap to see what’s actually taking up memory

Windows RAM at 91%? Use RAMMap to see what’s actually taking up memory

A reading of 91% RAM usage in Task Manager does not necessarily indicate that a PC is short on memory. Microsoft’s RAMMap tool provides a detailed breakdown of memory usage into categories such as Active, Standby, Modified, and Free memory. Task Manager presents a single total for memory usage, which can be misleading. An 8GB PC may show 7.1GB used out of 7.8GB without detailing the composition of that figure. Windows retains recently used app data in Standby, allowing for quick access, which means Standby memory is counted as Available. RAMMap categorizes memory usage as follows: - Active: Memory currently utilized by applications and system processes. - Standby: Cached pages that can be reclaimed by Windows. - Modified: Pages that have been altered and need to be written to storage. - Free and Zeroed: Pages ready for reuse. In a test, RAMMap showed 6.96GiB Active, 580MiB Standby, 263MiB Modified, and approximately 36MiB of Free plus Zeroed memory. Task Manager reported 685MB Available, mostly from cached memory. Committed refers to virtual memory allocated to applications, while Compressed indicates memory reduced in size by Windows. Resource Monitor offers a built-in view of memory usage. Emptying the Standby list using RAMMap reallocates memory rather than creating it, as shown in a scenario where Standby memory decreased from 996MiB to 258MiB, but Task Manager’s Available figure dropped from 1.32GB to 921MB. If Available memory consistently diminishes and the PC lags, adding more RAM may be necessary. Windows counts Standby memory as Available because it can be reclaimed quickly. RAM cleaner apps do not effectively increase Available memory, as Windows rebuilds the cache from the drive. Committed in Task Manager does not mean RAM in use; it refers to virtual memory allocated to applications.

Microsoft is actively rebuilding Windows 11 Search. What does it mean? Our deep‑dive answers every major question.

Microsoft is transforming the Windows Search feature in Windows 11 to improve speed, accuracy, and utility. The new experience will allow users to perform tasks directly from the Taskbar and will include file previews, enriched web results, and integration with Copilot. A preview is available through the Windows Insider Program, with more features expected later this year and deeper integration with the Start menu planned by 2027. The introduction of WinUI 3 will enhance performance and search accuracy. Users can perform actions like switching to Dark mode, enabling Bluetooth, adjusting volume levels, and arranging windows directly from the Search box. Future updates will include inline file previews and richer web results, with AI-generated responses for certain queries through Copilot integration. The new Windows Search experience is accessible to Insiders running specific builds and can be enabled manually if not visible after installing the latest preview build. It does not require a Copilot+ PC or an NPU, as it uses a small machine-learning model that operates locally. Currently, it cannot perform actions on connected phones, but a feature for sending text messages is in development. The redesigned interface will be smaller and include inline previews and richer file details, along with comprehensive web results. Filters will be introduced to refine search results by category. The rollout for Insiders began on October 7, 2026, with plans for richer search results and Copilot integration later this year, and the new Search experience is expected to be incorporated into the Start menu by 2027. A general availability date for all Windows 11 users has not been announced.
