If you uninstall Windows NT 4.0 Service Pack 2, the uninstall proceduremay not restore the original files.
If you apply Windows NT 4.0 Service Pack 2 (SP2) a second time with theCreate Uninstall Directory option chosen, the uninstall procedure may notrestore the original files.

In this scenario, the pre-SP2 files in the uninstall directory may bereplaced with Service Pack 2 files already in the Windows NT directorytree. The files are copied without warning. Future use of the ServicePack 2 uninstall feature may copy Service Pack 2 files back into theWindows NT directory tree instead of the original files.
To maintain the state of the files prior to the first application ofService Pack 2, use one of the following options:
  • When re-installing Service Pack 2, select "No, I do not want to create an Uninstall directory."

  • Prior to re-installing the Service Pack, make a backup copy of the $NtServicePackUninstall$ directory. After you apply the service pack again and choose to create an uninstall directory, you may replace the $NtServicePackUninstall$ directory with the backup copy.
If you wish to save the state of the files prior to the re-applicationof Service Pack 2 and use the Uninstall feature as currently designed,simply reapply Service Pack 2 with the uninstall directory creationoption enabled.
Microsoft has confirmed this to be a problem in Windows NT version 4.0Service Pack 2. We are researching this problem and will post newinformation here in the Microsoft Knowledge Base as it becomes available.
