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
Use direct shortcut
Press Ctrl + Shift + Escape simultaneously.
-
2
Show details
If necessary, click on More details.
-
3
Control resources
Sort Processor, Memory or Disc columns to identify the most consumer processes.
-
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.
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.
