Most of us Windows 7 and Windows 8 users are getting “get Windows 10” pop-ups inviting us to register for a free upgrade to Windows 10. If you don’t have a pop-up yet, don’t worry, you will be eligible for an upgrade at some point.
Windows 7 and Windows 8 users will have the chance to upgrade to Windows 10 for free when it comes out on 29th July. Microsoft is trying to get people to register for the free upgrade before it’s released; it’s just a marketing ploy. Whether or not you want to upgrade is up to you, it depends on whether you want the new features of Windows 10.
If you do decide to upgrade, there are two options; and “in-place upgrade” which (supposedly) leaves your files and software on the computer, or a “fresh install” where you backup your data (documents, photos, etc), wipe the hard disk, do a fresh install of Windows 10, install your software again, restore your data. For previous upgrades to Windows it was recommended that you do a “fresh install” to minimize the risk of things not working properly afterwards, and I expect that will be the best option for most people for Windows 10 too. In any case, I would recommend a backup of your data first. Also remember that some older software and hardware such as printers may not work with Windows 10.
When you do decide to upgrade, make sure you take your time, and maybe call in a professional to make sure it goes smoothly.
