I've got a few questions.

1) What happens if you try to update a copy of windows 7 that is not actually genuine?

2) I do have the "Reserve your Windows 10" icon in my system tray. However, there is nowhere to download Windows 10, all there is, is some slide images outlining windows 10 features. What do I do to get the actual upgrade in progress?

3) Do all my files that I have had before the upgrade from Windows 7 to Windows 10 stay? Ie. do I keep all my files, installed programs etc. after the Windows 10 update?

4) Should the actual installation of Windows 10 fail, will my computer be broken then?
