Hey guys,

Last evening, my friend helped me install Windows 8 operating system on my laptop. This morning I tried to exchange to the Office software, so I installed Office 2010 of MSDN to take place of Office 2003. You know it was activated by KMS. I wanna back up those activated files. But I'm not very clear about the specific steps. I have googled it online, but as a computer novice, I can not understand each step.

So pls do me a favor!

Thank you very much!
