powershell - How can I NOT display a selected column?

Question

I have Googled for a solution but found nothing relevant. I'm sure there is an easy way, but I would like to reformat a date column and NOT also print the original date column. What do you guys think?

Below is my (mostly) working Powershell code.

( Get-ItemProperty HKLM:SoftwareWow6432NodeMicrosoftWindowsCurrentVersionUninstall* | Select-Object DisplayName , InstallDate , @{ Name = "Formatted" ; Expression = { [ datetime ]:: parseexact( $_.InstallDate , 'yyyymmdd' , $null ).ToString( 'mm/dd/yy' ) } } | Where-Object { $_. InstallDate -ne $null } )

Answer 1

Like @AdminOfThing suggested:

( Get-ItemProperty HKLM:SoftwareWow6432NodeMicrosoftWindowsCurrentVersionUninstall* |  Where-Object { $_. InstallDate -ne $null } )|  Select-Object DisplayName,  @{ Name = "Formatted" ; Expression = { [ datetime ]:: parseexact( $_.InstallDate , 'yyyymmdd' , $null ).ToString( 'mm/dd/yy' ) } } 

Moving the Where-Object before the selection, gets the results after deleting InstallDate.
