"Contrary to what many journalists and members of the
user community have written in recent months, restoring
these files (WPA) will not restore your activation status following
a reformat and clean install."

| Have you ever wanted to reinstall Windows XP on a particular computer
| but chose not to because you weren't sure what you'd encounter when it came
| to Windows Product Activation (WPA)?
|
| Well, there's no need to be concerned because information about the
| current activation is stored in an encrypted database file named Wpa.dbl,
| which you can back up and then restore once you've reinstalled XP. Keep in
| mind that this technique allows you only to reinstall XP on the same
| computer--it isn't a hack to pirate the OS.
|
| Here's how to back up the Wpa.dbl file:
|
| 1. Insert a blank, formatted disk into the floppy disk drive.
|
| 2. Using Windows Explorer, navigate to the C:\Windows\System32 folder.
|
| 3. Right-click the Wpa.dbl file and select Send To | 3-1/2 Floppy.
|
| You can then reformat the hard disk and reinstall XP. Once the
| installation procedure is complete, follow these steps to restore the Wpa.dbl
| file:
|
| 1. Restart the computer.
|
| 2. Press [F8] when you see the message Please Select The Operating
| System To Start.
|
| 3. From the Windows Advanced Options Menu, select Safe Mode.
|
| 4. Using Windows Explorer, navigate to the C:\Windows\System32 folder.
|
| 5. Rename the new Wpa.dbl to Wpa.new.
|
| 6. Insert the disk that contains the backup into the floppy disk drive.
|
| 7. Copy the Wpa.dbl file from the floppy disk to the C:\Windows\System32
| folder.
|
| 8. Restart the computer.
|
| Since you're using the exact copy of XP that was previously installed,
| the original Wpa.dbl file will be accepted, and you won't have to go
| through all the hassle of reactivation.
