PowerShell is rather an amazing powerful scripting tool. For example, PowerShell can allow IT pros to automate most of the work and allows for remote access and work seamlessly while maintaining the highest level of security.
But for now, we are interested in the PowerShell command that can show us how long a computer has been on:
(Get-Date) - (gcim Win32_OperatingSystem).LastBootUpTime
This command uses the
Get-Date cmdlet to get the current date and time, and then subtracts the value of the
LastBootUpTime property of the
Win32_OperatingSystem class, which returns the date and time the operating system was last started. The result is the amount of time that has elapsed since the last time the computer was started.
