Thanks a lot daemonsOS.
I have chosen the option of slipstreaming XP with SP2 and then upgrade. I didn't know how to slipstream and from another forum "TechRepublic" I have got this link below, which guides for Slipstream:

I have upgraded it successfully. I need some information from you. Actually, a friend gave me this CD (windows XP professional). It is a legal copy. After upgrading I have come to know that it exceeds the maximum number of users. So, within 30 days I have to activate it. Is it possible to buy product key to activate it? or If I buy a fresh copy can I overwrite the one in my computer? I would be very grateful if you (or somebody) give me some guidance.
Thanks
