This information is provided by Get-ComputerInfo command of the powershell.
We can follow below steps to get the information.
Method-1 :
Find Os Up Time
Get-ComputerInfo -Property OsUpTime
Find Os Last Boot Up Time
Get-ComputerInfo -Property OsLastBootUpTime
But, the above methods are inefficient, because Get-ComputerInfo takes sometime to run.
Method 2 :
We first store the output of Get-ComputerInfo in a variable : $computerInfo.
The, we can extract other information from $computerInfo object.
$computerInfo = Get-ComputerInfo;
Find the Os Up Time
$computerInfo.OsUptime
Find the Os Last Boot Up time
$computerInfo.OsLastBootUpTime
We can extract other information from the $computerInfo object.
This way of scripting is more efficient.
