Windows XP Software not Genuine?

[Guest]

My computer keeps popping the statement that my windows xp Professional
Version 2002 is not genuine. However, I have the registration number. The
software worked for 4 years before the message started popping up. I kept up
with all my updates. Can anyone help me?
