SYMPTOMS
When you apply Service Pack 4 for Windows NT 3.51 Server or Workstation, the MoveFileEx API stops responding. Files that are marked for deletion or rename upon next restart are not deleted or renamed when you restart the system.



CAUSE
When you use the MoveFileEx API with the MOVEFILE_DELAY_UNTIL_REBOOT parameter, a setup program can mark a file for deletion, or rename, upon the next system restart. This is needed when a specific file is currently in use by the system and cannot be deleted.

The API appears to work, returns the correct error code, and the registry keys are created. However, on restart the files still exist and the registry keys are not deleted.



STATUS
Microsoft has confirmed this to be a problem in Windows NT 3.5 and 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
