Reinstall-windows-xp-without-product-activation

Okay, this is for the reinstallation of a previously installed legal copy of Windows XP.

"P.S. This will not enable you to install your copy of Windows XP on a different computer and bypass activation.

Isn’t it galling that we need to contact Microsoft for “permission” if we choose to reinstall a product that we already legally own and use, and have “stamped” so before?! This method of copyright protection has not exactly rollicked among customers. Well, no worries, there is a trick for getting around product activation for Windows XP when reinstalling.

If you have successfully activated the OS already, and if you are reinstalling it on the existing hardware, this trick should do just fine. Here it is:

1. Copy the file c:\windows\system32\wpa.dbl to a floppy.
2. Reinstall Windows XP.
3. Boot to a DOS disk if you are using FAT, or to the Recovery Console if using NTFS.
4. Copy the file from the first step above back to c:\windows\system32.
5. That’s it - because all of your hardware is the same as before, your copy of WinXP is still valid according to the previous activation."
