Start MenuDid you hear? Windows 10 is out today, and it’s a free upgrade from Windows 7 and 8.1.

But getting it isn’t necessarily a straightforward affair. While today is the debut of the new operating system, the update is rolling out in waves to users who reserved a free copy of the system already.

Don’t worry, you can still sign up for your free upgrade as well. Below, we’ve listed every way we can think of to get Windows 10.

You’ve already reserved your copy

Microsoft said it was rolling out Windows 10 in waves, starting with beta testers in its Windows Insider program. However, many people are finding that the upgrade is already downloaded and ready to be installed. Just look in the system tray for a notification that it’s ready and run the installer.

You haven’t reserved a copy but want to upgrade ASAP

You can still jump in line to reserve your free copy of Windows 10. Look in the system tray for the “Get Windows 10” icon and sign up for your spot in line.

The rollout might take weeks, but you’ll get notified when it’s your turn. Don’t fret about a later update; Microsoft is still working out some kinks in Windows 10 that you might avoid by getting a delayed upgrade.

You’re getting a new computer

Hardware manufacturers are already shipping devices with Windows 10 installed, so if you buy a new device you might already have the upgraded operating system.

However, even if the machine is running Windows 8.1 when you buy it, you can use the upgrade process above to reserve your free update.

You want Windows 10 but you don’t have Windows 7 or 8

If you’re not running Windows 7 or 8.1, you can’t get the free upgrade to Windows 10.

That means if you’re building a computer from scratch or want to install Windows on your Mac, you’ll have to pay. Users can get the Windows 10 Home for $119 or Windows 10 Pro for $199 from the Microsoft Store. Both versions are available for download or via USB stick.
