If you're still on 7, 8, or 8.1, now is the time to get your free update to 10. Click the little windows icon in the bottom right to get started. There's no reason to stay stuck in the past. 10 is better in every way to its predecessors. Safer, faster, and more feature-rich. It's a free update to the latest version, and it guarantees you security and feature updates for many years to come. It's silly to not take advantage of this offer. If you want to get it tomorrow, it'll cost you 129 bucks.
