SYMPTOMS
After you install Windows NT 3.51 Service Pack 4, if you attempt to install or upgrade any application that replaces Windows NT 3.51 files that are in use, the installation may fail. For example, when you attempt to install the Shell Technology Preview for Windows NT 3.51, the Setup fails and your computer no longer boots up.



CAUSE
Windows NT 3.51 Service Pack 4 replaces SMSS.EXE. The Shell Technology Preview Setup and some third-party installation programs call the MoveFileEx(MOVEFILE_DELAY_UNTIL_REBOOT) API to replace some Windows NT system files during a Setup reboot. The Service Pack 4 SMSS.EXE does not properly replace the files during reboot.



RESOLUTION
To correct this problem, apply the fix mentioned below.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51 Service Pack 4. 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):
