Dispatches from the Windows 10 frontline | Letters

I read Michele Hanson's article (G2, 24 May) with a wry smile, having spent time earlier modifying a friend's computer to prevent it updating to Windows 10, as the same thing had nearly happened to me last month.

What happens is that Microsoft installs a Trojan horse update along with all the normal ones. Sometime later this malware initiates an upgrade to Windows 10 without asking permission, and no method of cancellation without turning the computer off.
