I mean that if you were running Windows 7 or 8 and installed Windows 10 Preview through Windows Update you had to download a little program that enabled it. This is what I expect you will have to do with the free Windows 10 Upgrade when its released too, which I think is the same as how the Windows 8 pre order updates were delivered.
If your already running 10 then things will likely be different than for 'normal' people.

The next build wont be far round the corner anyway. I am remaining positive about this OS, I think it will be excellent! I just hope they don't focus too much on the extras and forget about good performance ALTHOUGH the build I ran before was more efficient than 8.1.
