Windows Fundamentals for Legacy PCs build 2600.2907

Windows Fundamentals for Legacy PCs build 2600.2907 is the RTM build of Windows Fundamentals for Legacy PCs (or FLP for short). As Windows FLP is designed to be a minimal operating system, it does not include some components from Windows XP such as games, Microsoft Paint, or the Compatibility Mode framework.

Setup
Windows FLP is distributed in Windows Image (or WIM) format, similar to that of Windows Vista. As such, the setup process runs only in graphics mode and relies on the First Boot Agent.

User interface
Windows FLP notably uses the older Windows 2000 icon set by default (as it starts in 800x600 at 16-bit color during first boot), while keeping the Luna theme from Windows XP. The build also has a unique brand banner utilizing the Windows Longhorn–Vista era Windows logo and font set (similar to that of Vista build 5219 and later).

Alternate login screen
WinFLP uses by default the login prompt from Windows 2000 with the Ctrl+Alt+Del requirement. However, the Windows XP welcome screen is also available but hidden in the system. To enable it, go to Control Panel\User Accounts\Change the way users log on or off. If a prompt saying that offline files need to be disabled, follow the steps to disable them. Once offline files are disabled, you can select the Use welcome screen option and apply changes. The new login screen is practically the same as Windows XP.

Fast user switching
The user switching feature from Windows XP is also present but disabled in this build. To enable it, go to the same route as the Welcome screen and disable offline files in case they aren't. Then you can select the Enable fast user switching option and apply.

Installation
To install this build on VMware, set the SCSI controller to BusLogic, and the disk type to IDE, otherwise it will result in a bugcheck with code 0x7B.

User accounts
Standard user accounts can't be created through Control Panel, and  must be used instead.

Windows XP Professional reference in Help and Support
Help and Support identifies itself as Windows XP Professional, meaning that some topic's links might be non-functional due to the lack of certain XP features.
