This is the Powershell script I wrote:
$varCompList = Get-ADComputer -Filter "Name -like '*Name of Computers*'" -Properties OperatingSystemVersion | select DNSHostName, OperatingSystemVersion
foreach ($System in $varCompList){
$Restult=switch ($System.OperatingSystemVersion){
"10.0 (20348)"{"Server 2022"}
"10.0 (19042)"{"Server 2019 20H2"}
"10.0 (18363)"{"Server 2019 1909"}
"10.0 (17763)"{"Server 2019 1809"}
"10.0 (14393)"{"Server 2016"}
}
}
echo $varCompList
It displays all the Servers like it should but the OperatingSystemVersion is still displayed as 10.0 (14393).
What am I missing?
You're currently assigning the mapped OS names to a variable, but you never use it for anything and you never update the original input object.
Instead of assigning the result to a variable, assign it to the OperatingSystemVersion property on each object instead:
foreach ($System in $varCompList){
$System.OperatingSystemVersion = switch ($System.OperatingSystemVersion){
"10.0 (20348)"{"Server 2022"}
"10.0 (19042)"{"Server 2019 20H2"}
"10.0 (18363)"{"Server 2019 1909"}
"10.0 (17763)"{"Server 2019 1809"}
"10.0 (14393)"{"Server 2016"}
default { $_ }
}
}
The default case will ensure you preserve the original version string for any computer that doesn't have any of the listed versions installed.
