System uptime may be demonstrated via Task Manager, Command Prompt, and PowerShell. Through Task Manager, go to Performance tab, choose CPU, and check the Up time parameter. In case of using PowerShell, use Get-Uptime command to get information about how long the system has been up in Windows operating systems that support it. Moreover, you can get the last time when the computer was started by using system information command and count the time. System uptime is helpful to analyze recent restarts and resolve performance issues. It is all described in the DataRecovee Windows Uptime guide.
