Microsoft makes Windows 10 an 'automatic' update
As of February 2nd, Microsoft has modified the Windows 10 update to be 'recommended' which may mean millions of Windows 7 and 8.1 users will automatically download the new operating system.
The default option concerning updates for 7 and 8.1 makes it so recommended updates are automatically downloaded to your PC. In general this is a good thing as it ensures that your software is completely up to date without your direct input. However it also means that instead of having the option to reject the Windows 10 upgrade, it will begin to download and install immediately.
It is possible to turn this option off however and this image (courtesy of ExtremeTech.com) shows the Windows update control panel where you can toggle the setting on or off.
There's no doubt that Microsoft is keen for all Windows users to run the latest OS but for many, change is something that should be avoided for as long as possible. If you're one of those people then make sure to follow the necessary steps to prevent your PC updating with Windows 10.
Full instructions on how to manage Windows 10 notification and upgrade options can be found on the official Microsoft site.
