During mini-setup of a Windows XP SP1 sysprep image or of a Windows XP riprep image, you are prompted for the product key, even though you included an encrypted product key in the Sysprep.inf file.

The problem will occur if:

1. You encrypt the product key in the Sysprep.inf file by using the winnt32.exe /encrypt command with a Windows XP sysprep image or with a Windows XP riprep image.

2. You install the sysprep image or the riprep image.

3. You upgrade the image to SP1, using update.exe.

4. You run the sysprep -reseal command or the Riprep command on the image again.

Before you run the sysprep -reseal command or the riprep command:

1. Run the following setPID.bat file:

                              @echo off                              setlocal                              set query=reg QUERY "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v ProductID                              for /f "Tokens=3" %%a in ('%query%^|findstr /i /c:"ProductID"') do (                               set ProductID=%%a                              )                              reg ADD "HKLM\SYSTEM\Setup\PID" /v PID /D %ProductID:~0,5%270 /F                              endlocal                              
2. Run the sysprep -reseal command or the Riprep command.

NOTE: If the original image was installed from a slipstream of SP1 this behavior does NOT occur.
