Query results from table

I am writing a script to query what edition of Windows machines are on. So far I have the following code:

    $ASSETNUM = Read-Host "Please enter a valid asset tag"

Get-WmiObject Win32_OperatingSystem -ComputerName $ASSETNUM | select PSComputerName, Caption, OSArchitecture, Version, BuildNumber | FL

if (Caption = "Microsoft Windows 10 Enterprise"){
    Write-Host "This works"
    } else {
    Write-Host "This did not work"
    }

The first part before the if statement works as intended. However, I wish to query the "Caption" to be able to run a further function afterwards. However, I'm at a loss on how to query this. The Write-Host parts are just for testing until I get this working.

Thanks in advance for all your help!
