Things that I missed in Desktops were:

• you couln’t move opened programs between desktops
• Firefox and Winamp (possible some other programs too) wouldn’t work on other desktop if they are allready opened on one
• desktop backgrounds would disapeer

New program that I found is called Vista/XP virtual desktop manager. Some of the options that it provide are:

• Full screen desktop/window manager/preview with full drag and drop managing
• Desktop switch indicator
• An infinite number of desktops
• Watch the windows move in real time as you drag them around in the window manager
• Multiple monitor support
• Window menus
• Tray icons for each desktop
• Per-desktop backgrounds
• Configurable colors, fade speeds, hotkeys, etc.
• Uses Vista’s live thumbnails
• XP support
• And much more!

You can find more info about program and download it on this link.

Here are some screenshoots.

Here is a quote from web site of a JkDefrag:

JkDefrag is a disk defragmenter and optimizer for Windows 2000/2003/XP/Vista/2008/X64. Completely automatic and very easy to use, fast, low overhead, with several optimization strategies, and can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows. Included are a Windows version, a commandline version (for scheduling by the task scheduler or for use from administrator scripts), a screensaver version, a DLL library (for use from programming languages), versions for Windows X64, and the complete sources.

Program is very simple, just unzip and run it, no installation, no configuration and what is most important it works well.

On home page of JkDefrag you can download sources, executables and read some more info about it.

Read tips before defragmenting, they will increase speed of defragmentation.
