Use Get-CimInstance with the ClassName win32_operatingsystem

You can query the ClassName win32_operatingsystem and select from there the computername csname and the last bootup time lastbootuptime

Get-CimInstance -ComputerName 'DC01' -ClassName win32_operatingsystem | select csname, lastbootuptime

Show last bootuptime for multiple computers

If you want to do that for multiple computers you can for example do it wit a foreach loop:

# First query the computer from which you want to have this information:
$computer = Get-ADComputer -Filter * | where Name -Match dc
# Now get the lastbootuptime for every computer in the computer array:
foreach($c in $computer){
    $computername = $c.DNSHostname
    Get-CimInstance -ComputerName $computername -ClassName win32_operatingsystem | select csname, lastbootuptime
}

Which other information can you get from this class?

If you’re curious what other information you can get from this class you can simply run a Get-Member which will list you all properties and methods:

A way to search a specific setting over all GPOs

Generate a GPO Report over your Domain

You can generate a GPO Report over your Domain either in a XML or HTML file and then search through that file.

To generate a XML use this command:

Get-GPOReport -All -Domain "domain.com" -Server "DC01" -ReportType XML -Path "C:\GPOReports\GPOReportsAll.xml"

To generate a HTML file you can use this command:

Get-GPOReport -All -Domain "domain.com" -Server "DC01" -ReportType HTML -Path "C:\GPOReports\GPOReportsAll.html"

All GPO settings will be included in this Report file. So you can search through that file and find your settings.
