Peek is a tiny native Windows utility published by HaBaDEDE, designed for diagnosing transient processes, file locks, and user interface elements. It falls within the system utilities and diagnostics category, specifically targeting developer and administrator troubleshooting workflows on Windows. The software is currently available in version 0.1.0, with one version listed in total. Peek is described as a portable tool that combines three focused capabilities in a single package. The first tool, Ghost, captures short-lived processes and flashing windows, addressing the common problem of observing system events that appear and disappear too quickly to identify through conventional monitoring. The second tool, Unlock, identifies which processes are holding a particular file open, which is relevant when a file cannot be deleted, moved, or modified because an unknown process maintains a lock on it. The third tool, Focus, inspects the Win32 and UI Automation element located under the mouse pointer, making it useful for examining application interfaces, control hierarchies, and accessibility-related element properties. These three tools collectively serve use cases in debugging, software development, quality assurance, UI automation testing, and general system administration. A defining characteristic of Peek is its operational footprint: it runs offline, requires no user accounts, collects no telemetry, and depends on no additional runtime, which distinguishes it from tools that require installation of frameworks or background services. Because it is portable and native, the utility can be executed directly on a Windows system without a setup procedure. This design makes Peek suitable for ad hoc diagnostics on machines where installing dependencies or connecting to external services is impractical or undesirable. Overall, Peek positions itself as a compact, self-contained inspection toolkit for Windows users who need quick answers about fleeting processes, locked files, and interface elements without infrastructure overhead or privacy concerns.
