Hi... Welcome to Just Answer Support...
I am Rojus... Hope I can assist you to solve this issue...

May I know how did you try to activate windows ?

Was it through net or over phone ?

kindly go through the steps to activate windows

Here are some time-tested tips that will get you through the mandatory process in five minutes or less.

Bring up Activation

If Windows isn’t already prompting you to activate your software, or if you’re unsure if you need to, you can easily bring up the activation wizard by going to Start, Run, and running oobe/msoobe /a. It’s okay to run this command if Windows is already activated, too, so don’t worry about it undoing what may already be complete.

Try Internet Activation First

If you have an internet connection when activating Windows, attempt to use the online route first. In the Windows Product Activation Wizard, choose “Yes, lets activate Windows over the internet now”, followed by “No, do not register with Microsoft”. You may receive a friendly “Thank you!” and your copy of Windows will be good to go.

If internet activation fails and the Wizard complains about “too many activations” or an “incorrect product key”, you still have the option of calling Microsoft’s toll free number to activate Windows. As long as the Wizard doesn’t report “invalid product key,” options are still open. An “invalid” (not “incorrect,” mind you) key is one reported or detected as pirated, so you’ll have to find some other way to make your software go.

Phone Activation

Activating Windows via phone is about as enjoyable as a trip to the dentist, but knowing exactly which buttons to push and the right words to say can help cut your time in half and get you the necessary code.

If your online activation from above failed, click the Telephone button to generate an Installation ID, which you’ll read off to a customer service representative shortly. Call the number for your appropriate country, and you’ll enter into a phone menu system which would like nothing more than for you to activate by reading the numbers onscreen. The software behind the menu, however, does the same checking as the online activation method — meaning if your online activation failed, so too will the automated phone activation. Press 0 on the phone keypad when asked if you are calling to activate Windows XP (the first opportunity you are prompted for input). Like many newer phone menus, it will respond “I see that you’d like to transfer to a customer service representative”, and subsequently try to convince you to go back to the automated system. Ignore the pre-recorded woman’s somewhat rude request to go back, and press 1 to to talk to a human.

After a short delay and the distinct possibility of listening to some poorly chosen music, a representative will ask for either the first six digits of your Installation ID, or the full set. (The first six digits of the Installation ID are the only real keys to generating a Confirmation ID, however the reps more often than not ask you to read off the rest of the group. The rest of the numbers are encoded values detailing some very basic hardware details about your computer.)

If asked “Is this the first time you’re activating Windows?”, say yes. If you say no, the representative will ask for an explanation as to why you’re re-activating Windows.

If asked “Did you purchase the software from a retail store?”, say “It came pre-installed with my computer.”

As a final time-kill (their system sometimes takes a minute to generate Confirmation IDs on days with a particularly heavy load), you may be asked for your Product Key (Windows serial number).

After you’ve given them the necessary information, the representative will read the Confirmation ID to you, which you can simply type into the provided fields. Using these methods, it takes about 4 minutes to activate Windows on average.

Hope this will help you to solve the issue...

Activation methods

You can activate your copy of Windows XP by using any one of the following methods:

• Activate Windows XP by using the Internet
  
  If you use this method, the Windows Product Activation wizard establishes a connection to the activation server, sends your installation ID, and then processes the activation request.
• Activate Windows XP by using your modem
  
  If you have a modem but you do not have an Internet connection, the wizard detects your modem and establishes a connection to the activation server through your phone line.
• Activate Windows XP by phone
  
  If you do not have a modem or an Internet connection, you can activate Windows XP by calling a Microsoft customer service representative. The Activation Wizard displays the toll free number that you can dial.

The following sections in this article describe how to use each of these methods.
