Download Windows 10 without activating it: Technically, you can download Windows 10 from Microsoft (not the app store version) and simply not activate it, which means you don’t actually pay for it. It turns out this is safer than it sounds because Microsoft is pretty lax about enforcing activation. Your copy of Windows shouldn’t be shut down, and you should still have access to your apps, etc. However, there are limitations. Microsoft will constantly bug you to activate Windows 10 every time you log in and show a big activation sign on your desktop. You won’t be able to do any personalization, color changes, or other types of modification to Windows until you activate, either. There’s also no chance of technical support. However, it’s a pretty great deal for getting a lot of Windows 10 functionality for free…although there’s no guarantee Microsoft won’t change this in the future.
