Do you wish to delete or uninstall it?
To delete, you can delete the WinNT folder (that should get most of it cleaned out). I would suggest that you make a backup first and rename the folder instead of deleting it. IF everything still works on your system over a few weeks, the delete the renamed folder.
If the OS is on its own partition (without any other needed files/folders) just reformat that partition.
Do not advertise that you are removing the OS - M$ has hired guns that will lock you away for blasphemy.
