If your goal was to "fix" a shutdown problem, try these established methods:
Windows will scan for missing or corrupt files (like shutdown.exe ) and replace them from the internal cache or your Windows XP installation CD.
Type: expand D:\I386\SHUTDOWN.EX_ C:\Windows\System32\shutdown.exe (Replace D: with your CD drive letter).
If SFC fails, you can manually expand the file from an XP CD: Open Command Prompt .
