Windows Embedded for Point of Service build 592

Windows Embedded for Point of Service build 592 is an update to Windows Embedded for Point of Service, referred to as Windows Embedded for Point of Service 1.1. It is based upon Windows XP SP2, just like the earlier releases of Windows Embedded for Point of Service.

Setup
The setup interface is entirely different as to Windows XP's setup interface. This is the first release of Windows to use the new Windows Preinstallation Environment for the setup interface, replacing the gradually-aging i386 setup interface. Upon booting, you will be greeted by a new window, asking for whether you'd like to open a command prompt dialog or not. This window typically stays for about roughly 3 seconds, until it automatically launches the setup application. This also replaces the Shift+F10 key binding during setup, however that was re-added in Windows Vista.

Many pages were either introduced or replaced entirely, with the application inclusion page making its return - however it only includes a couple features that you can add. Other pages, such as networking and summary pages, have been added, whilst other pages, such as the disk formatting page, have been majorly enhanced. It is also still possible to format the primary partition to install Windows on with FAT32.

After completing the first stage of setup, the second stage will consist of what is called the First Boot Agent, which will install the majority of software included with the operating system and such. It will take some time, depending on the software you have decided to include with the operating system. It is also likely for Windows to reboot during the First Boot Agent several times.

WEPoS.WIM
Similarly to Windows Longhorn, this release of Windows has packaged all of the operating system's features inside a WIM archive, however it was referenced as "WEPoS.WIM", rather than "INSTALL.WIM" in Windows Longhorn builds. Inside the WIM archive, there are 8 additional smaller images, each of them serving its own purpose. For example, the first small image inside the archive is responsible for the core files of the operating system.
