How To Transfer Windows Serial Key

Software piracy is rampant, and Microsoft is the target for a large percentage of piracy due to their dominance in the market. They have a right to try to stop or at least control that privacy and product activation seems to be a fair way of ensuring that only legitimate software owners get to benefit from using it.

How to link your Windows 10 product key to a Microsoft account If you're using a local account, use this guide to link your Windows 10 product key to your Microsoft account for easier re-activation.

That said, many users abhor the process of product activation. It may be because they have had problems activating and have had to call the toll-free number and wait to talk to a Microsoft support agent who then read them some 278-character long activation code. OK, that's a slight exaggeration. Or maybe they just feel that it is some sort of invasion of privacy or that Microsoft is acting as 'Big Brother' and monitoring their actions.

No matter the reason, there are plenty of users who would rather never go through the product activation process again. Unfortunately for those users, they may very well run into a situation where they do. Product activation monitors the system configuration. If it detects a major hardware change or even too many minor hardware changes within a set number of days then it crosses the threshold and requires reactivation.

Reactivating Your Microsoft Product

Users who reformat their hard drive and perform a clean installation of the operating system will find that they need to reactivate the product. But, as long as the new installation is on the same system and there won't be any hardware changes, it is possible to transfer the existing product activation and skip having to go through the product activation process again. Follow the steps below to save the activation status information in Windows XP and restore it once your system is rebuilt. (We also have instructions on how to change the Windows activation key in Windows 7 and Windows Vista.)

Save Activation Status Information in Windows XP

  1. Double-click My Computer.
  2. Double-click on the Cdrive.
  3. Go to the C:WindowsSystem32 folder. (You may have to click on the link that says Show the contents of this folder.)
  4. Find the files 'wpa.dbl' and 'wpa.bak' and copy them to a safe location. You can copy them on a floppy drive or burn it to a CD or DVD.
  5. After you have reinstalled Windows XP on your reformatted hard drive, click No when asked if you want to go ahead and go through the activation process.
  6. Reboot your computer into SafeMode. (You can either press F8 as Windows is booting up to see the Windows Advanced Options menu and select SAFEBOOT_OPTION=Minimal.
  7. Double-click My Computer.
  8. Double-click on the C drive.
  9. Go to the C:WindowsSystem32 folder. (You may have to click on the link that says Show The contents of this folder.)
  10. Find the file 'wpa.dbl' and 'wpa.bak' (if it exists) and rename them to 'wpadbl.new' and 'wpabak.new.'
  11. Copy your original 'wpa.dbl' and 'wpa.bak' files from your floppy disk, CD, or DVD into the C:WindowsSystem32 folder.
  1. Restart your system. (If you followed the directions in starting Windows XP in SafeMode, you may need to go back into MSCONFIG to turn off booting into SafeMode).

Voila! Your Windows XP operating system is now reinstalled on your reformatted hard drive, and you are all activated without having to actually go through the product activation process.

Remember, though, this won't work for transferring activation information from one computer to another or if you alter the hardware because then the information contained in your 'wpa.dbl' file will not match the configuration of the computer. This trick is only for reinstalling Windows XP on the exact same computer after formatting the hard drive.

Activation is a protection mechanism implemented in Windows 10 and earlier versions against piracy. It first appeared in Windows XP and exists with different changes and improvements in Windows Vista, Windows 7, Windows 8 and Windows 10. When activation is successful, usually it indicates that your copy of Windows is genuine. There may be times when you need to deactivate your copy of Windows 10 in order to transfer your license to another PC. Here is how you can deactivate your copy of Windows 10.

Activation verifies that your copy of Windows is not used on more devices than the license allows. If you are about to sell or give away your PC but want to keep Windows 10 installed there, it is a good idea to deactivate it. Deactivation is also useful if you want to use your product key on some other PC and stop using it on the current PC.

In this article, we will see how to deactivate Windows 10 by uninstalling the product key. Additionally, we will see how to install another product key instead.

To deactivate Windows 10 by uninstalling the product key, you need to do the following:

  2. Type or paste the following command:
  3. Wait till the command finishes its work. At the end, you will see the following message:

Windows 10 will become deactivated. You can visit the Settings app and check out the 'Activation' page and check the activation state. It will look like this:

After you deactivate Windows 10, you might be interested in clearing the product key from the Registry so it cannot be viewed with special apps and scripts.

Please keep in mind that if you reach the online activation limit, e.g. by activating many PCs with the same key, you may have to activate your copy of Windows by phone since the online activation will fail.
