Windows XP Themes

This post reviews the most popular free for download themes for Windows.

Themes for Windows XP often requires different types of heavy and resource demanding 3rd party software, e.g. like ThemeXP and others. In this post I have collected the most popular themes that do not require additional 3rd partysoftware.

The Luna Theme
The Luna Windows XP theme is the traditional Windows XP theme. The Luna themeaka the official Windows XP Style is available in three different color schemes; Blue (the default), Olive Green, and Silver.

The Energy Blue Theme
The Energy Blue theme is a theme concept produced by Microsoft and introduced in 2004 for the Windows Media Center and Windows XP Tablet editions. It is composed of a new redesigned wallpaper (inspired by Windows XP Bliss) and a new desktop theme and skin. The concept presents aesthetic brilliant and relucent blue and green colors. The Energy Blue theme is not only available for Windows Media Center and Windows XP Tablet editions, but also regular Windows XP editions.

Download the Energy Blue theme here.

The Royale Themes
The Royale theme is a new theme for Windows XP that has leaked out of Microsoftand onto the web. The theme appears to have come out of a beta version ofWindows Media Center 2005 that was in testing. The Royale theme is an aesthetic theme and comes with two color schemes Royale (a blue theme) and Royale Noir (a black theme). The Royale theme is refreshingly different to the traditionalWindows XP Luna theme.

Download the Royale theme here and the Royale Noir theme here or here (1).

The Zune Theme
After the Royale and the Royale Noir themes were leaked onto the web Microsoftdecided to release a modified version of the Royale theme called Zune – perhaps to promote the release of their new invention – the Zune. The Zune theme is different to the Royale and the Royale Noir themes by having orange controls and a orange start-button.

Download the Zune theme here at Microsoft

Matching Firefox Themes
Until now I have been unable to find matching themes for Mozilla Firefox. I’m currently searching the net for a Firefox theme that matches the Royale Noir theme.

Xen Howto: Install Windows

This short guide describes how to install Windows XP orWindows 2003 Server on Xen. It provides an overview of theDebian Linux Etch installation, and detailed steps for installing and configuring Xenand starting the Windows XP or Windows 2003 Server


  • CPU with either Intel’s Vanderpool (IVT – Intel Virtualization Technology) orAMD’s Pacifica Technology (AMD virtualization)
  • Windows iso-image

First you need to install Xen on Debian Etch:

sudo apt-get install xen-linux-system-2.6.18-4-xen-686 libc6-xen bridge-utils

Boot into the newly installed Xen enabled Linux kernel

sudo reboot

Then adjusted the network settings in /etc/xen/xend-config.sxp. Enabling the network bridge:

(network-script network-bridge)

Install Xen IO Emulation tools:

sudo apt-get install xen-ioemu-3.0.3-1

Create a directory for the virtual machine files e.g. /home/xen/domains/win01 and create a disk image for the virtual machine’s primary disk.

mkdir /home/xen
mkdir /home/xen/domains
mkdir /home/xen/domains/win01
sudo dd if=/dev/zero of= /home/xen/domains/win01/disk.img bs=1M count=4096

Establish a Xen machine Configuration file (/etc/xen/win01.cfg) like this

kernel = '/usr/lib/xen/boot/hvmloader'
builder = 'hvm'
memory = '256'

# Disks
disk = [ 'file:/home/xen/domains/win01/disk.img,ioemu:hda,w',
'file:/home/cc/iso-images/WindowsXP-SP2/image.iso,ioemu:hdc:cdrom,r' ]

# Hostname
name = ‘win01′

# Networking
vif = ['type=ioemu, bridge=xenbr0']

# Behaviour

The ready to fire up the new machine and start the Windows installation in a vnc terminal.

xm create win01.cfg

After the virtual machine is started – a VNC server port should be available on port 5900 at the Xen server’s IP, e.g. – A VNC XEN Client session is depicted here.

If an error like this shows up

Error: Device 0 (vif) could not be connected. Backend device not found.

You should check your that you have enabled the network bridge, “(network-script network-bridge)”, in /etc/xen/xend-config.sxp and restarted the xen deamon by /etc/init.d/xend restart

For more on creating Xen virtual machines read this guide, which outlines the features of the xen-tools package.
