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.

Windows/Exchange Server October 2026 issue: Analysis and Workarounds

On October 13, 2026, Microsoft released security updates for Windows Server that unintentionally affected Microsoft Exchange Server, causing significant disruptions approximately 24 hours after installation. Users reported issues such as database services failing, resulting in unresponsive email and Outlook Web Access access. Microsoft acknowledged the problem and is investigating it. The updates targeted supported Windows Server and Microsoft Exchange versions 2016, 2019, and SE. By October 15, reports of severe issues, including the inability to connect to the server and halted email delivery, emerged. The error message associated with the disruption is "MapiExceptionMdbOffline: Unable to make connection to the server. (hr=0x80004005, ec=1142)." Despite these issues, the Exchange Admin Center still showed databases as connected and mounted. Unofficial workarounds, including a registry edit and a PowerShell script, have been suggested to mitigate the problems.

Why Antivirus Flags Game Tools and How to Verify Downloads Safely

In gaming, tools such as utilities, beta applications, and modding tools are often distributed as APK, IPA, or desktop files, and it is essential to investigate their origin, version, and any security warnings before installation. Antivirus software flags potential threats based on known malicious signatures, behavior patterns, and reputation data. Tools that modify game clients may receive heightened scrutiny, and classifications like “HackTool” or “Riskware” do not definitively indicate a file's functionality. Identical game utilities can exist on various platforms, and a familiar website does not guarantee authenticity. It is crucial to verify the publisher, update date, version, and installation method of a file. The SHA-256 hash verifies file integrity but does not ensure safety from malware. Calculating a file hash can be done using specific commands in Windows, macOS, or Linux. Multi-engine scanning platforms like VirusTotal provide insights, but a lack of detections does not guarantee safety. Even if a file matches its reference hash and raises no alerts, it may still violate online game terms. A pre-installation checklist includes confirming the publisher, checking file types, comparing SHA-256 hashes, reviewing security findings, keeping antivirus protection enabled, and consulting platform rules. A cautious approach integrates source verification, file integrity checks, security assessments, and compliance with platform regulations.

How to supercharge your Windows 11 PC with this built-in automation tool

Windows 11 includes a Task Scheduler that automates repetitive tasks to enhance productivity. To set up a task, users should open Task Scheduler, select "Create Task," and fill in details under General, Triggers, Actions, Conditions, and Settings. It's important for laptop users to avoid scheduling tasks that run every five minutes to maintain low-power idle states. The "Run with highest privileges" option should be used cautiously for security reasons. Three recommended automations include: 1. Using WinGet to keep software updated with the command winget upgrade --all --silent --accept-package-agreements --accept-source-agreements --disable-interactivity, scheduled weekly. 2. Disabling unnecessary startup applications and launching them with a delayed logon trigger to reduce startup clutter. 3. Automating tasks with PowerShell for file transfers or system maintenance, ensuring they run during idle times or when connected to AC power. Windows also performs some maintenance tasks automatically, such as deleting temporary files and optimizing drives.

Microsoft warns fake CAPTCHA tests are hijacking Windows PCs

Microsoft has warned Windows users about a cyber threat that disguises itself as a CAPTCHA test, where cybercriminals use fraudulent verification pages to trick users into executing commands that can install malware. This tactic involves users being directed to a compromised website that presents a fake verification window, prompting them to copy text and execute it in the Windows Run dialog. This method allows attackers to bypass antivirus software by pre-loading malicious scripts disguised as harmless images in the browser's cache. Once activated, the malware collects system information, steals data, and maintains long-term control over the system. Microsoft recommends using robust security software and being aware that no legitimate service will ask users to copy and paste commands into system dialogs.

These 3 popular Windows apps run faster as CLI tools: Here’s how to switch

Windows provides graphical tools for various tasks, but terminal commands can be more efficient. Three utilities that serve as alternatives to File Explorer, Task Manager, and Notepad are zoxide, btop, and bat, all of which can be installed using winget. zoxide is a directory jumper that simplifies navigation through folder structures by learning user habits. It can be installed with PLACEHOLDERf0ff8219c0950297 and requires a line added to the PowerShell profile for activation. Users can jump to directories by typing PLACEHOLDERb9546a80b5ad16aa followed by part of the folder name, and it adapts over time based on usage patterns. btop is a system monitor that displays processor, memory, disk, network, and process data on a single terminal screen. The Windows version, btop4win, can be installed with winget install aristocratos.btop4win. It features live graphs, allows navigation via keyboard and mouse, and provides real-time updates on resource consumption. Users can filter and sort processes and terminate them directly from the interface. bat is a command-line file viewer that shows file contents with syntax highlighting and line numbers, eliminating the need to open Notepad. It can be installed using winget install sharkdp.bat and allows users to view files directly in the terminal. It integrates with Git to highlight changes and manages longer files with a pager for easier scrolling. These tools enhance efficiency for common tasks in Windows by providing quick access and streamlined workflows through the terminal.
