  This may resturn better results depending on the property
  Get-ItemPropertyProperty -Path HKCU:\Software\ScriptingGuys\Scripts -Name version
  As an example I was looking for a correct Windows Build number which at first should be 
  [System.Environment]::OSVersion.Version
  The issue I had was with Windows returning a 0 for revision on  the Revision property when I knew I had installed service packs that should have updated the build.

  The issue I had was with Windows returning a 0 for revision on  the Revision property when I knew I had installed service packs that should have updated the build. 
  In my case I found that the Registry Key “HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\” Ccontained much more information including a UBR value, which appears to be the revision number for the build. To Duplicate the output of the [System.Environment]::OSVersion.Version I came up with the following:
   
  $WindowsVersion = New-Object -TypeName PSObject
  $WindowsVersion | Add-Member -MemberType NoteProperty -Name Major -Value $(Get-ItemPropertyValue -Path ‘HKLM:\Software\Microsoft\Windows NT\CurrentVersion’ -Name CurrentMajorVersionNumber)
  $WindowsVersion | Add-Member -MemberType NoteProperty -Name Minor -Value $(Get-ItemPropertyValue -Path ‘HKLM:\Software\Microsoft\Windows NT\CurrentVersion’ -Name CurrentMinorVersionNumber)
  $WindowsVersion | Add-Member -MemberType NoteProperty -Name Build -Value $(Get-ItemPropertyValue -Path ‘HKLM:\Software\Microsoft\Windows NT\CurrentVersion’ -Name CurrentBuild)
  $WindowsVersion | Add-Member -MemberType NoteProperty -Name Revision -Value $(Get-ItemPropertyValue -Path ‘HKLM:\Software\Microsoft\Windows NT\CurrentVersion’ -Name UBR)
  $WindowsVersion
   
  Which returns the correct results
