Windows XP Service Pack 1 volume license product key encryption

• Windows XP Professional Volume License Media
• Windows XP Professional Volume License Product Key
• Windows XP SP1

1. Copy the I386 Directory and all subdirectories from your Windows XP Professional Volume License Media CD-ROM to a directory on your hard disk. For example, copy them to C:\Flat.
2. Download and extract Xpsp1.exe to a directory on your hard disk.
3. Run the following command to integrate SP1 into the I386 directory:
   c:\xpsp1\update\update.exe -s:c:\flat
   
4. Run the following command to encrypt your Windows Setup answer file:
   c:\flat\winnt32.exe /encrypt:"xxxxx-xxxxx-xxxxx-xxxxx-xxxxx:y" /unattend:filename
   This command uses the following place holders:
   
   • xxxxx-xxxxx-xxxxx-xxxxx-xxxxx is your Volume License Product Key.
     
   • y is a value ranging from 5 to 60. This is the time in days that you want this script to be valid for.
     
   • filename is the script that you want to encrypt the Volume License Product Key in.

Notes

• To encrypt the product key in a answer file, you must run Winnt32.exe from a computer that is running Windows XP or later. You cannot encrypt the product key on a computer that is running either Windows 2000 or Windows 98.
• This procedure works for any valid Windows Setup answer file (for example, Unattend.txt, Winnt.sif, Sysprep.inf, or Ristndrd.sif ).
• You have to install from a Windows XP Professional source directory into which Windows XP SP1 has been integrated.
• 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.

Main module path: <c:\flat\i386\winnt32u.dll>
