If you are prompted by your existing Windows 7 or 8 to upgrade to Windows 10 make sure you have a full image backup in case things don’t go as planned.

The free upgrade will expire on the 29th of July 2016, so there is still some time to reflect before taking the plunge.

Most upgrades including the recent unintended upgrades have gone reasonably smoothly, however there will always be some adjustments required, one of which is to check that your antivirus has survived the jump.
