I had bought a License copy of Windows 7 ultimate and installed on my laptop with a help of friend. Due to some issues I had to format the hard drive and had to reinstall the Windows 7 operationg system. It got installed properly, but I see a yellow ballon icon on the right bottom of the screen asking me to activate the it again.

Should I click on it and activate, becuase I had already activated it during my first installtion a year back.

Same goes for Microsoft Office 2010 as well. Please suggest what should I do?
