Windows XP build 2600.1106

Windows XP build 2600.1106 is the official RTM build of Windows XP Service Pack 1. The source code to this build, as well as Windows Server 2003 RTM, was leaked on 23 September 2020.

On 3 February 2003, Service Pack 1a was released to remove the Microsoft Java Virtual Machine as a result of legal battle between Sun Microsystems and Microsoft over the Java VM code; SP1 and SP1a are otherwise identical.

Bugs

 * A zero day activation bug may occur if installed on the current date. Attempting to activate will result in no installation ID being generated, making it impossible to activate by normal means, unless you update to Service Pack 2.
