Tips: Turn OEM XP into a retail genuine xp_windowsxp

Decrypt the Windows XP Setupp.ini.

The Setupp.ini of Windows XP determines how the OEM XP CD is run and modifies it to turn your OEM CD into a formal retail version.

　　 Steps:　　

1. Enter the WinXP CD i386 path to find Setupp.ini.

2. Open, the contents of the file are displayed as follows:

Extradata=707a667567736f696f697911ae7e05

pid=55034000

The PID is the part we are interested in, and the following figure determines whether the XP CD is a retail, OEM or Enterprise licensed version.

3. It's time to get to the big part.

First, we divide the PID number into 2 parts, the first five digits determine how the CD is run, for example, the retail CD allows you to complete the installation or upgrade, and the OEM CD can only be fully installed. The last 3 digits determine the CD key that the CD accepts, and you modify it to obtain a retail CD that accepts the OEM CD Key.

Remember, the numbers don't change, but you can change other numbers to match them, for example:

Retail = 51882335

Volume License = 51883 270

OEM = 82503 oem

If you want a retail CD that accepts the retail CD key, simply modify the last line of Setupp.ini to:

pid=51882335

If you want a retail CD that accepts the OEM CD key, modify the last line of Setupp.ini to:

Pid=51882oem

Note that you do not want to change the PID to an enterprise-licensed version, because the version cannot be activated and activation must have the enterprise authorization key.

Did you succeed in the experiment?
