Issue with get-wmiobject and foreach loop

Question

I'm trying to run a get-wmi win32_operatingsystem command and when i pipe in a few computers to the $comp variable everything works fine. When i run this against all the computers in AD i get no results back in my .csv
im stumped as too why... any thoughts ?
$comp = (Get-ADComputer -filter * | where {$_.Enabled -eq 'True' } | select name)
foreach ($computers in $comp) {
     Get-WmiObject -Class win32_operatingsystem -Property * -ComputerName $computers | select PSComputername,OSArchitecture, Name | Export-Csv C:\Get-OsVersionAllComputers.csv -Append -NoTypeInformation

If you are just typing commnds like this to get quick infor this can be compacted very easily and test a piece at a time:
# step 1
Get-ADComputer -filter 'Enabled -eq $true'
#now add wmi
Get-ADComputer -filter 'Enabled -eq $true'|%{gwmi win32_operatingsystem -cn $_.Name }
# add the select
 Get-ADComputer -filter 'Enabled -eq $true'|%{gwmi win32_operatingsystem -cn $_.Name } |
    Select PSComputername,OSArchitecture, Name 
# add the export.
Get-ADComputer -filter 'Enabled -eq $true'|%{gwmi win32_operatingsystem -cn $_.Name } |
    Select PSComputername,OSArchitecture, Name |
    Export-Csv C:\Get-OsVersionAllComputers.csv -NoType
Using this approach PowerSHellmakes building complex commands very easy.  JUst start thinking in declaritive termms in the pipeline.
