Should I upgrade to Windows 10? Are you upgrading from XP or Vista?
Windows 10 will be a free upgrade for existing Windows 7 (SP1) and Windows 8.1 users. This offer doesn’t extend to XP or Vista and you can’t simply upgrade even if you're willing to pay. Updating requires a clean install.Bottom line
While Windows 8 was an unpleasant surprise for a lot of people, Windows 10 goes a long way to putting that right. The OS is clean, familiar, and easy to understand, plus it has a wealth of new, helpful features that you'll actually want to use. The fact that it's free for the majority of existing Windows users, and can be rolled back quickly to the previous version if you don't like it, really makes it very, very easy to recommend.My Experience upgrading Windows 7 and Windows 8 portable and desktop
