Microsoft has attracted a bit of press around how those who upgrade to Windows 10 may find their internet connection being used to upload the installation files to their neighbours.

It's called peer to peer file sharing and is usually used in the dark corners of the internet to illegally share copyrighted material, such as music, television shows and movies at best, and far worse things other times.

Personal computers are getting a major makeover this week, as Microsoft releases the final version of Windows, free for selected devices.

Windows 10 will begin arriving today, as a download from the internet on personal computers running Windows 7, 8 or 8.1, for users who have pre-registered their machines with Microsoft. It will also come pre-installed on new personal computers, or can be bought on a DVD or downloaded from the Windows Store.
