How to make Windows XP Genuine, for free!
First, open up the Start menu, and select “Run”. A small Window will appear. Type in “Regedit” and push Enter (or click OK). Then, expand “HKEY_LOCAL_MACHINE”, and select “Software”. Expand the “Software”, too. (Always expand menus.) Then expand “Microsoft”, expand “Windows NT”, then “CurrentVersion”, and search for “WPAEvents”. Click once on the folder called “WPAEvents”.
   Now, look on the right side, and double click “OOBETimer”. A small window will pop-up again. In the window, You will see some Letters and numbers. You only have to edit or delete something. After You’re done with that,  Click “OK”.
Go to Start, and open up “Run” again. This time You have to type this path in the text box:
%systemroot%\system32\oobe\msoobe.exe /a
 
A bigger Window will pop-up this time. It says: “Let’s activate Windows”. You will have three options:

1. Yes, let’s activate Windows over the internet now.
2.  Yes, I want to telephone a customer service representative to Activate Windows.
3. No, Log me off.

 
 You have to select the second option.
   Then, click “Next”.
After that, click on “
Change Product key”.
 
You have to put the Product key in there! And the Product key is:

BDGMY-QJYMD-YHPQ4-QRV3H-C4MRQ
