get_boot_history
Lists recent boots newest first with boot/shutdown timings, failures, and shutdown reasons to diagnose slow starts, unexpected restarts, or crashes.
Instructions
Lists the machine's last boots, newest first, from the system's own logs. Each start in its steps: the firmware, the system's loader, Windows to the sign-in screen, the sign-in, and the sign-in to the desktop, with Group Policy's time and the slow sign-in steps (the time the sign-in screen waited for someone is apart). How the session before it ended: clean, a stop error (blue screen) with its code and dump, the power button held, or not shut down at all with when it was last seen running; who asked for a shutdown or restart (the program, as which user, the reason, its words: Windows Update, an installer, the user), how long shutting down took and how long the machine was off. What failed as it started (services that did not start or answer, drivers that did not load), and how the session went: how long it ran, its sleeps, the services that stopped unexpectedly. Where Windows keeps its own boot measurement it adds that and what it found slower than usual; on Linux, this boot's timings and slowest units from systemd. Use it when a PC starts slowly, restarted by itself or keeps crashing; list_startup_items lists what starts at sign-in. It only reads.
