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.

Windows 11 Spotted Keeping Thumbnails of Deleted Photos

Windows 11 uses a thumbnail caching mechanism to store previews of images in specific databases located in %LocalAppData%MicrosoftWindowsExplorer, such as thumbcache32.db and thumbcache1024.db. When a user deletes an image, the corresponding thumbnail may remain in the cache, as deletion does not automatically remove it from the thumbnail database. The cache retains only reduced versions of images, not the original files, which is significant in digital forensics where thumbnails can provide insights even when original files are missing. Users can manage their thumbnail cache using the cleanmgr tool to clear saved thumbnails or disable thumbnail caching through the Local Group Policy Editor or File Explorer settings.

Windows XP had a hidden database of broken apps, and Microsoft used it to trick them into working

Windows XP, released in 2001, was designed with a hidden compatibility database to support legacy software. This database, located in the C:WINDOWSAppPatch folder, contained approximately 200 compatibility fixes at launch and utilized a sophisticated matching system based on file size, checksum, version, and date. Windows XP could modify its behavior for specific applications through the use of shims, which acted as intermediaries to adjust application calls to the Windows API. Notable shims included Win98VersionLie, which faked the Windows version for compatibility, and EmulateHeap, which replicated the Windows 95 memory management style. Microsoft recognized that blocking applications relying on undocumented features could hinder user upgrades, as many organizations depended on legacy software. The compatibility fixes were managed through DLLs in the AppPatch folder, allowing the core operating system files to remain unchanged. Microsoft continued to enhance XP's compatibility with updates even years after its release.

Why Endpoint Detection and Response Is No Longer Optional

Traditional antivirus software relies on a signature-based model that compares files against a database of known malware, which limits its effectiveness against modern threats. Cybercriminals have adapted by using polymorphic malware and fileless techniques that evade detection. Endpoint Detection and Response (EDR) continuously monitors device activities, tracking process activity, network connections, and file changes to detect behavioral patterns indicative of attacks. EDR also enables rapid response actions, such as isolating affected devices and terminating malicious processes. Small and medium businesses are increasingly targeted by attackers who exploit the limitations of traditional antivirus solutions. Relying solely on antivirus software creates vulnerabilities, making it essential for organizations to incorporate EDR for enhanced security.

The Evolution of Endpoint Security: Why EDR Represents a Fundamental Shift From Traditional Antivirus

Organizations that rely on technology face evolving cyber threats that traditional antivirus software struggles to address. Traditional antivirus detects known malware through signature matching but is limited in its ability to catch new or modified threats. Modern cyberattacks utilize techniques like polymorphic malware and fileless attacks to evade detection. Endpoint Detection and Response (EDR) tools have emerged as a solution, focusing on analyzing behavior rather than matching known threats. EDR continuously monitors endpoints, collects data on system activities, and uses behavioral analysis to identify suspicious actions. This allows for real-time responses to threats, such as isolating affected devices or rolling back changes made by ransomware. EDR is essential for all organizations, including small businesses, which are often targeted by attackers. It should be part of a broader security strategy that includes traditional antivirus, regular updates, employee training, access controls, and backups. When considering EDR options, businesses should prioritize response speed, visibility, reporting capabilities, and integration with existing IT support.

Windows 11 can keep thumbnails of photos you deleted. Here’s how to remove them

Windows retains thumbnails in a cache file named thumbcache_256.db, but it does not save a thumbnail of every deleted photo. Other operating systems, including macOS and Linux, also use thumbnail caching. Users can access their thumbnail cache by navigating to %LOCALAPPDATA%MicrosoftWindowsExplorer, but this will not show deleted images. Thumbnails are created only when images are displayed in Explorer’s thumbnail view. Windows allows users to clear the thumbnail cache using the Disk Cleanup tool, and there is an option to disable thumbnail caching in Windows 11 Pro and higher. The cached thumbnails do not guarantee persistence and do not represent original files. Windows also keeps records of application launches in Prefetch, maintains entries for USB devices in the USBSTOR registry key, saves Wi-Fi networks and passwords, and can keep clipboard history and recent file shortcuts.

Windows 11 can keep thumbnails of photos you deleted. Here’s how to remove them

A recent post on X claims that Windows retains a thumbnail of every deleted photo in a file named thumbcache_256.db, which has raised privacy concerns among users. While Windows does maintain a thumbnail cache for efficiency, this practice is not unique to Windows, as other operating systems like macOS, Linux, and Android also use similar systems. Users can inspect or clear their thumbnail cache by accessing specific database files in the Windows Explorer directory. The claim that Windows retains "every photo you’ve ever deleted" is misleading, as thumbnails are only created when images are viewed in thumbnail mode. Windows does not cache every file, and thumbnails must exist before they can be cached. Additionally, Windows keeps app launch records in Prefetch files for performance optimization, maintains entries for USB devices in the USBSTOR registry key, retains records of Wi-Fi networks and passwords (which are encrypted), and can keep clipboard history and recent file shortcuts. Caching previews is common across various operating systems, and Microsoft is focused on user consent and privacy as it enhances Windows 11 with AI functionalities.

What Is Happening with PostgreSQL 19?

Postgres 19 is experiencing delays in its release schedule, with Beta 4 scheduled for September 24, 2026. The development team is prioritizing quality over timelines, leading to the reversion of 53 significant features during the beta phase. Notable feature reversions include SQL Property Graph Queries, ALTER TABLE MERGE/SPLIT PARTITION(S), UPDATE/DELETE FOR PORTION OF, GROUP BY ALL, a change to default TOAST compression, nontext output formats for pg_dumpall, JSON_TABLE ON ERROR cascading, fast defaults for domains with nonvolatile constraints, logical replication database-specific snapshots, nested query tracking, and online data checksums. The majority of these reversions are due to design flaws, incorrect results, or compatibility issues. There are also at-risk features identified, including RI fast-path FK checks, REPACK / REPACK CONCURRENTLY, and Postgres_fdw statistics import. Despite these challenges, promising features such as pg_plan_advice, parallel autovacuum, ON CONFLICT DO SELECT, and logical replication enhancements are still anticipated in PG19. AI tools are being utilized in the development process to identify bugs and create test cases. Postgres 18 remains a reliable upgrade target, while features like property graphs and GROUP BY ALL are now planned for PG20.
