A. Windows XP includes an option to perform a boot defragment, which places all files required for booting next to each other on disk to provide a faster boot time. The OS enables this option by default, but you can check the status and enable this option by performing the following steps:

  1. Start the registry editor (regedit.exe).
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction.
  3. If Enable isn't set to Y, double-click Enable and set the value to Y.
  4. Click OK.
  5. Close the registry editor.
  6. Reboot the machine.

If you want to disable boot defragment, set Enable to N.
