Alternatively, you can use the Command Prompt to retrieve boot times. Here's how:
- Press the Windows key + R to open the Run dialog box.
- Type cmd and press Enter.
- In the Command Prompt, type systeminfo | findstr /C:"Boot Time" and press Enter.
This command will display the most recent boot time, along with other system information. If you want to see a list of previous boot times, you can use the eventlog command:
- Type eventlog and press Enter.
- In the Event Log, navigate to Windows Logs > System.
- Use the filter option to display only events with ID 12.
Using the uptime Command (Linux/Mac)
On Linux and Mac systems, you can use the uptime command to retrieve the system's uptime and previous boot time:
