At my workplace we have been given the chance to purchase Windows 7 or 8 for £8.33. I currently use Vista 64 Home Premium. While my system has been very stable for a number of years (apart from taking about 5 minutes now to load everything and be able to use the mouse) I am unsure if the upgrade route is the way to go. If I did this, would I need to change all my drivers and back up all my data (photos, music etc). I am being too cautious or is this a no-brainer? Thanks.
