Windows XP build 2600.1106 is the official RTM build of Windows XP Service Pack 1 released on 9 September 2002. The source code for this build, along with the RTM build of Windows Server 2003, was leaked on 23 September 2020.

This release would be used as the base for Windows XP Tablet PC Edition and Windows XP Media Center Edition. It was also pushed out to Windows XP Embedded and Windows XP 64-Bit Edition.

Changes from Windows XP RTM[edit | edit source]

  • Added the Set Program Access and Defaults Control Panel applet, which can be used to set default web browsers and media players.
  • Added support for .NET Framework.
  • Added support for USB 2.0.

Service Pack 1a[edit | edit source]

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

Bugs[edit | edit source]

Activation[edit | edit source]

Just like Windows XP RTM build, 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 the user updates to Service Pack 2.
