file (for example, Unattend.txt, Winnt.sif, Sysprep.inf, or Ristndrd.sif

- The /encrypt command automatically adds the "Productkey=" line to your file or
updates an existing Productkey or ProductID entry.
- When the time period specified has ended, the user is
prompted to manually enter a product key during Setup.
When you run this command, you do not receive any dialog boxes
or error messages. To determine whether the command is successful, see the
%WINDIR%\Winnt32.log file. The following is a sample command to encrypt a
product key that is not valid for Volume License media:
Main module path: <c:\flat\i386\winnt32u.dll>
PID is not valid or not a valid VL key.
