REACTIVATE XP FROM FLOPPY

If you ever need to re-install Windows XP you can save yourself the 
bother of going through the Product Activation procedure by making a 
copy of the activation files stored on your PC. Simply pop in a blank 
floppy, open Windows Explorer and work your way to C:\WINDOWS\system32 
and copy the files wpa.dbl and wpa.bak to a floppy disc or USB memory 
stick and keep it in a safe place. Following reinstallation, when you 
are asked to of you want to Activate Windows XP decline the kind offer 
and let the installation continue. When it has finished reboot XP and 
press F8 to start the computer Safe mode. Open Windows Explorer, work 
your way to C:\WINDOWS\system32 once again, rename the existing wpa.dbl 
and wps.bak files (call then wba.old 1 and 2 for example) and copy your 
backed your wpa files from the floppy or memory stick into the same 
location. Exit Windows and reboot.
