Hi, I'm french, sorry if I make spelling errors, I use Google translator to talk to you. I installed Windows 7 Ultimate on my computer, but since the trial period has been exceeded, my computer shuts down about every hour .. In my file is downloaded, there was Windows_7_Toolkit_1.7, I turned with it. But, Windows asks me to activate the product key. How do I activate my downloaded Windows 7? I have a Packard Bell Imedia 8612, which I completely reformatted. Thank you for your help she will be invaluable.
