I looked at this script, and it will always return "Operating system is not supported" because in the script $major and $minor are strings, I was able to confirm that with the commands:
$major.GetType()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True String System.Object
$minor.GetType()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True String System.Object
I recommend updating the script to this, and I highlighted the changes:
$version = (Get-WmiObject Win32_OperatingSystem).Version
[int]$major = $version.split(".")[0]
[int]$minor = $version.split(".")[1]
if ($major -gt 6 -or ($major -eq 6 -and $minor -gt 1)) {
Optimize-Volume -driveletter $pwd.drive.name -Analyze -verbos
} Else {
Write-Output "Operating system is not supported."
}
Here is the original script:
$version = (Get-WmiObject Win32_OperatingSystem).Version
$major = $version.split(".")[0]
$minor = $version.split(".")[1]
if ($major -gt 6 -or ($major -eq 6 -and $minor -gt 1)) {
Optimize-Volume $pwd.drive.name -Analyze -verbos
} Else {
Write-Output "Operating system is not supported."
}
