The desktop is an integral component of the Windows operating system
and cannot be removed. However, you do have the option of disabling the
resource-hungry Active Desktop and using the classic user interface
instead. The biggest advantage of doing this is that your PC will feel
much snappier. Unfortunately, it is much harder to disable the Active
Desktop in Windows XP than it was in previous versions of the operating
system - it requires a change to the registry.

To open the registry editor, go to "Start, Run", type regedit
and hit "OK". Find the entry

"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer"

and create the DWORD values ForceActiveDesktopOn and NoActiveDesktop
. To do so, right-click into the right-hand window and select "New,
DWORD". Then change the binary value of the registry key called
"ForceActiveDesktopOn" to 0 and that of "NoActiveDesktop" to 1.

Now quit the program and restart your computer.
