A common frustration that people experience when re-installing an edition of Windows XP -- that's not volume-licensed or preactivated -- is having to reactivate their copy of Windows. Granted, Microsoft has done a lot to make product activation a lot less of a hassle than it could be with its Product Activation (PA) technology, but there are still plenty of folks -- myself included -- who would rather not deal with PA at all, or at least as minimally as possible. Also, if you're forced to reactivate Windows in a place where there's no network connection (and you loathe the idea of using the phone activation system), this is a convenient way to save yourself a step.
  1. Before you reinstall Windows, you'll need to make a copy of the system's product activation data. This is stored as a pair of files named WPA.BAK and WPA.DBL in the %SystemRoot%\System32 folder (usually \Windows\System32).
  2. If your existing copy of Windows is bootable, you can copy these files out normally. If not, you have to boot to the Recovery Console or use some other tool to copy out the files. The files are very small (only 15 K or so each) and can be copied to a floppy, another hard drive or anywhere else that you see fit.
  3. Reinstall Windows XP normally. You can reformat the hard drive when you do this, if you choose to do so.
  4. After the reinstallation is finished, reboot the computer in Safe Mode.
  5. Go to the %SystemRoot%\System32 folder and rename the WPA.BAK and WPA.DBL files to something else (_WPA.BAK_ and _WPA.DBL_ should work).
  6. Copy in the backed-up WPA.BAK and WPA.DBL files to that directory.
  7. Reboot normally. Your new installation of Windows should be activated.

Bear in mind that this is not a "hack" or a way of circumventing product activation altogether. It will only work if the PA data is being backed up from and then restored to the same system -- or one that does not have significantly different hardware than the original.
