Product activation and its advantages on computer
Hello, for your recommendations please.
What is product activation and how is it advantageous to my computer, if I use it?
Will there be any modifications from Product Activation’s version, when I use Windows XP?
Do I have to upgrade my computer?
If yes, is it better to install a new one, like Windows Vista?
Will I have to restore and save my documents and files and make configuration again?
