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. To prevent this happening, you need to uninstall update number KB3035583 (go to control panel, Windows update, installed updates, then find the right update KB3035583 right click on it and click uninstall). You may want to stop Microsoft installing it again by switching off automatic updates (Windows update, change settings). I have heard many stories of people who have upgraded to Windows 10 and found numerous problems using their computer, including lost data.
