Quickly open Task Manager to scan CPU, memory, disk and applications.

Avant de commencer : adaptez toujours les commandes et manipulations à votre environnement. Sur un système de production, prévoyez une backup ou un retour arrière lorsque l’action peut modifier la configuration.

Étapes à suivre

  1. 1

    Use direct shortcut

    Press Ctrl + Shift + Escape simultaneously.

  2. 2

    Show details

    If necessary, click on More details.

  3. 3

    Control resources

    Sort Processor, Memory or Disc columns to identify the most consumer processes.

  4. 4

    See applications on startup

    Open the Start Applications section to find out what unnecessary programs are.

À retenir

  • Do not complete a system process without knowing what it is for.
  • A 100% disk use requires to identify the responsible process before any action.
Technical deep dive

Task Manager: go beyond a single CPU percentage

Technical checkpoints

  • The Details tab correlates process name, PID, user and usage; PID is the key for linking services, ports and logs.
  • High memory can be useful cache; also examine committed memory, paging and overall pressure before calling it a leak.
  • Instant CPU usage should be observed over several seconds to distinguish a spike from sustained load.

Practical reference

From a suspicious process, note the PID then cross-check with Get-Process, services or network sockets.

Get-Process -Id <PID> | Format-List *

Topic-specific pitfalls

  • Ending a system or server process without identifying its role can cause a wider outage.
  • Task Manager does not replace PerfMon, Resource Monitor or logs for historical analysis.

How to validate

  • The responsible process and PID are identified with a reproducible measurement.
  • The symptom is correlated with a resource or event, not just a visual spike.
