The computer takes forever to shut down, then suddenly finishes in two seconds
My computer consistently takes an extremely long time to shut down, often hanging on the closing screen for several minutes before it finishes completely. However, after a long delay, the final phase of the shutdown process suddenly completes in just two seconds, making me suspect some background process or service is causing the prolonged wait before the system finally cuts off.

The long pause followed by a quick power-off usually means Windows is waiting for a service, application, driver, or pending write to finish. Close applications manually, disconnect nonessential USB devices, and test shutdown again. Open Event Viewer and inspect Applications and Services Logs > Microsoft > Windows > Diagnostics-Performance > Operational for shutdown events; note any component and duration named there. Install current Windows updates and obtain chipset, storage, and graphics drivers from the computer manufacturer. Run a clean boot and test several shutdowns. If the delay disappears, re-enable services and startup items in groups until the responsible component returns. Also run DISM /Online /Cleanup-Image /RestoreHealth, followed by sfc /scannow, from an elevated terminal. Do not force power-off during the delay unless the machine is completely unresponsive, because pending writes could be lost. Persistent delays without a useful event should be captured with Windows Performance Recorder for support analysis.
