If your Send To is missing when you right click in Windows NT Explorer, Microsoft recommends that you verify the following entry is present in the registry, using Regedt32:
HKEY_CLASSES_ROOT\AllFileSystemObjects\Shellex\ContexMenuHandlers\Send To\<No Name>
According to Microsoft, this blank Value name is a type REG_SZ entry
and should have a string value of (7BA4C740-9E81-11CF-99D3-00AA004AE837)
I could not find this entry on any Windows NT computer I checked.
If you create the above entry (and reboot), and Send TO still doesn't function, try setting the <No Name> string value to
\{7BA4C740-9E81-11CF-99D3-00AA004AE837\} instead.
If this still doesn't work, I recommend that you run the following REG file using regedit /s <Drive:>\Folder\FileName.REG:
REGEDIT4
\[HKEY_CLASSES_ROOT\CLSID\\{7BA4C740-9E81-11CF-99D3-00AA004AE837\}\]
@="Microsoft SendTo Service"
"flags"=dword:00000001
\[HKEY_CLASSES_ROOT\CLSID\\{7BA4C740-9E81-11CF-99D3-00AA004AE837\}\InprocServer32\]
@=hex(2):25,53,79,73,74,65,6d,52,6f,6f,74,25,5c,53,79,73,74,65,6d,33,32,5c,73, 68,64,6f,63,76,77,2e,64,6c,6c,00
