Learn about Windows PowerShell
Summary: Learn a one-liner Windows PowerShell command to see how long a computer has run.
How can I use Windows PowerShell to find out how long my computer has been running since last boot up without writing a script?
Use the Win32_OperatingSystem WMI class and the LastBootupTime property, and then subtract the value of the current date/time that comes from Get-Date:
(Get-Date) - (Get-CimInstance Win32_operatingSystem).lastbootuptime
Thank you very much for this simple and interesting article. Here the parameters for a remote session:
(Get-Date) - (Get-CimInstance Win32_operatingSystem -CimSession pc10).lastbootuptime
For some reason, the script above says that my computer has been running for 8 consecutive days, while I turned it on about 20 minutes ago. It was powered off, not hibernated, so that's not the issue. Any idea what may cause this?
