reactivate xp from a floppy disk

[microsoftne]

Circumstances arise where you'll need to reinstall Windows XP on your machine when no hardware changes have been made. Rather than go through the reactivation process, create a floppy disk to back up the activation status file. Once XP has been reinstalled the floppy can be used to restore the previous activation status.

Create the Activation Status Floppy Diskette
Navigate to %systemroot%\system32 folder.
Copy the wpa.dbl file to the floppy diskette.
Reinstall Windows XP
Reinstall XP in the normal manner. After the install is completed and the XP Out Of Box Experience (OOBE) appears where you'd normally activate the product, decline to activate and let the installation complete.
Activate the XP Reinstallation
Restart the computer and use the F8 key to bring up the Advanced Boot Options menu.
Select Minimal Safe Mode using Up and Down Arrow Keys and press Enter.
Navigate to %systemroot%\system32 folder.
Rename the existing wpa.dbl file to wpa.noact.
Using the floppy diskette, copy the previously backed up wpa.dbl file to the %systemroot%\system32 folder.
Reboot the computer.
