demarrage du PC

Hello,

Thank you for posting your question on our forum.

There are several ways to find your PC's startup time on Windows:

1. Event Viewer

- Open Event Viewer by typing it in the Start menu search and pressing Enter.
- Navigate to Applications and Services Logs > Microsoft > Windows > Diagnostics-Performance > Operational.
- Filter the log by Event ID 100 (this event shows the boot time in milliseconds).
- The latest event will show your system's boot duration, which you can convert from milliseconds to seconds by dividing by 1000.
- For shutdown time, look for Event ID 200 in the same log.
- This method gives you precise boot and shutdown durations.

2. Command Prompt

- Open Command Prompt as administrator.
- Run the command: systeminfo | find "System Boot Time" to see the last boot time in a readable format.
- Alternatively, run: wmic path Win32_OperatingSystem get LastBootUpTime to get a timestamp you can decode to find when the system last started.
- Subtract this time from the current time to calculate uptime.

3. Task Manager

- Open Task Manager (Ctrl+Shift+Esc).
- Go to the Performance tab and select CPU.
- Look for the Uptime value, which shows how long your PC has been running since the last boot.
- Please note that this shows duration since last startup, not exact boot time.
