Why Windows 11 still won’t let you name a file CON, and Microsoft’s explanation goes back to MS-DOS

In Windows 11, certain names such as CON, PRN, AUX, and NUL are reserved as they correspond to specific devices, preventing users from naming folders with these terms. These reserved names date back to DOS 1.0, where folders did not exist. The names have specific functions: CON refers to the console, PRN to the printer, AUX to an auxiliary device, and NUL to a null device that discards output. Attempts to rename a folder to any of these names result in an error message indicating the device name is invalid. Adding extensions to these names does not bypass the restriction, as names like NUL.txt are still treated as equivalent to NUL. Despite some changes in Windows 11, the prohibition against using these reserved names for files or folders remains in place due to legacy compatibility concerns.

Latest Windows Updates Introduce Exchange Server Issues

Organizations using on-premises Microsoft Exchange Server are experiencing stability issues after the October 2026 Windows Server updates, which Microsoft has confirmed can lead to unreliable Exchange services, especially in environments with heavier workloads. Administrators have reported problems such as connectivity failures with Outlook on the web, disruptions in mail flow, and complications with database availability groups (DAG), all emerging post-update. This bug affects Exchange Servers on Windows Server versions 2016, 2019, 2022, and 2025. Microsoft has identified that the issue is related to limitations in Endpoint Mapper requests and has recommended a registry-based mitigation to improve capacity and reduce service degradation. The default limit of 512 simultaneous Endpoint Lookup calls may be insufficient under heavy load. Microsoft is investigating the issue and will provide further information. Organizations are advised to maintain critical security updates while implementing additional mitigation measures and closely monitoring affected systems until a long-term solution is found.

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.

Why Windows 11 still ships with Windows 95’s memory manager hidden inside it

Windows 11 includes a compatibility feature called EmulateHeap, which allows legacy applications to access Windows 95’s memory management system. This feature is present in the Windows 11 26H2 version and enables users to run older applications that depend on the original memory manager. Microsoft modified Windows 95's memory management specifically for the game SimCity, creating a workaround that prevented memory from being freed immediately. EmulateHeap was developed to address compatibility issues for various applications that relied on Windows 95's memory management quirks. It works by redirecting an application’s heap calls to mimic the behavior of Windows 95. EmulateHeap is part of the Compatibility Administrator tool within the Windows Assessment and Deployment Kit (ADK), which supports Windows 11 26H2. Users can locate EmulateHeap in the Compatibility Administrator by creating a new database and searching for compatibility fixes. Despite this support, some users have reported issues with certain games after updates. Microsoft continues to support Windows 95’s heap manager for select older applications but has discontinued support for others, like 3D Pinball, due to technical limitations.

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.

Windows 11’s last Secure Boot deadline hits Monday, Microsoft reveals what happens to your PC

Microsoft Windows Production PCA 2011, the certificate for signing the Windows boot loader, will expire on October 19, 2026. This follows the earlier expiration of two other 2011 certificates in June 2026. PCs without the new certificates will still boot and receive standard updates but will miss out on new security enhancements for the early boot process. The new certificates from 2023 are replacing the 2011 certificates. The KEK certificate, essential for authorizing updates to signature databases, and the Microsoft UEFI CA 2011, which signs third-party boot loaders, will also be replaced by new certificates. Users can check their Secure Boot status through the System Information tool or Windows Security. Microsoft is gradually rolling out the new Secure Boot certificates through Windows Update, and users are advised not to disable Secure Boot to avoid complications. Dell will not issue BIOS updates for platforms that reached their end of service life before January 1, 2026. The transition to Secure Boot has faced challenges for older PCs, and developers are advised against pinning Secure Boot certificates in their applications. Multiple restarts may be required for full integration of the new certificates.
