Today's the day! Windows 10 is now available in 190 countries as a free upgrade to Windows 7 or 8.1 owners. Replacing an OS is no one's idea of fun, but we're actually looking forward to this one. First off, we'll be leaving behind the most hated version of Windows ever (sorry, Vista). In return, we'll get one Microsoft was so confident in that they skipped version 9 altogether because hey, Windows 10 sounds better. So how to get it? We've got a handy guide, and Microsoft has info here, but if you already reserved your free upgrade, hang in there, as Microsoft says it's rolling out in waves.
Organizations will start to see the new version on August 1st. The computer you have should work just fine, as the minimum requirements haven't changed much from Windows 7 and 8: A 1GHz processor, 1GB of RAM (2GB for the 64-bit version) and 20GB of free space. The whole thing will take 30-45 minutes, according to Microsoft, not counting the 4-8GB download. Speaking of which, you'll likely need to be patient, as the roll-out may actually break internet traffic records.
As for what's in it for you, the answer is plenty: you'll get a much improved interface that takes the best of Windows 7 and 8.1, the new Edge browser, Cortana and better modern apps. You can read more about it in our Windows 10 review, but to cut to the chase, we gave it a stellar 91 rating.
