Hi

Today I just found a very handy command that will display the computer/ last reboot in PowerShell;

Just  copy and paste into your console, as you can

Get-WmiObject -Class Win32_OperatingSystem -ComputerName localhost | Select-Object -Property @{n="Last Boot Time";e={[Management.ManagementDateTimeConverter]::ToDateTime($_.LastBootUpTime)}}

If you get tired you always can use:

systeminfo | find "Time"
