As some of you may know, Microsoft's latest offering of Windows 10 is a 'free' update. However, lately it has a habit of downloading and installing WITHOUT your express permission !! This has happened to many of my friends here in UK.
Luckily, there is an easy way to stop this from happening if you don't wish to 'upgrade'... There is a small program which is quick to download and install and easy to operate, called 'Never10' and you can obtain it free from www.grc.com/never10.htm
Just save it to your desktop, click on the Icon and follow the easy steps....

It's only applicable to current installations of Windows 7 or 8.1
