In addition, the .NET Framework shipped with the following versions of Windows but not as truly integrated OS components:

  • Windows XP Home and Professional SP1 includes the MSI-based .NET Framework 1.0 + SP2 in the Additional Components folder on the installation CD.  It is not an OS component on this OS.
  • Windows XP Home and Professional SP2 includes the MSI-based .NET Framework 1.1 + SP1 in the Additional Components folder on the installation CD.  It is not an OS component on this OS.
  • Windows XP Home and Professional SP3 includes the MSI-based .NET Framework 1.1 + SP1 in the Additional Components folder on the installation CD.  It is not an OS component on this OS.
  • Windows Server 2003 R2 includes the MSI-based .NET Framework 2.0.  It appears in Add/Remove Windows Components as an OS component, but selecting it simply invokes the MSI-based installer.  The MSI can be repaired and removed using Add/Remove Programs regardless of whether it is installed via the standalone MSI or via the Add/Remove Windows Components UI.
