Thanks a lot. The reason why I'm reactivating my window is I can't logon anymore. After I had re-installed my OS and activated it then did all the updated upto IE7. Then I had started seeing this window before I logon that I needed ti activate my window but everytime I activate it the pop up window would show that I had already activated my window and press OK. Now I can't totally logon.
I had tried Safe Mode but Windows would say that I cannot activate it at "safe mode". I called Customer support "activation" and they told me that it is not an issue on windows activation so they gave me tech support number instead.
