How do I activate a Windows key?

A Windows product key is a 25-character code. You can enter it during installation or add it later by going to Settings > System > Activation > Change product key. Some PCs use a digital license instead, which needs no key. The same Activation page lists your activation status.

Can I turn Windows Home into Windows Pro with a key?

Yes, as long as your copy of Windows Home is already activated. Open the Activation page, select Change product key, and enter your Windows Pro key to start the upgrade. Pro adds BitLocker drive encryption, Remote Desktop, and the option to join a domain.

What happens to my Windows key if I change hardware?

Your key or digital license is tied to your computer's hardware. If you make a major change, like swapping the motherboard, Windows will ask you to reactivate. Linking your Microsoft account to your license beforehand lets the Activation troubleshooter handle the reactivation. Keep in mind that a copy of Windows is usually licensed for one PC only, so a key for one computer is not meant to run on several.

How do I redeem an Office key?

Go to setup.office.com, log in with a Microsoft account (existing or new), and enter the product key. You only redeem a key once. Next, install the apps, open one, and follow the prompts to activate. The account-based Office 365 Pro Plus listing may come with its own delivery steps, so check its product page.

What should I know about VPN and cleanup plans?

The device count in a NordVPN title matters because each account can connect a limited number of devices at once. A router, for instance, uses just one connection slot but covers every device on its network. Avast Cleanup Premium is a subscription app: after installing it, you may need to activate it manually. Go to Settings > My subscription, choose Enter activation code, and type in the code from your order confirmation, including the hyphens. You can find more options in our VPN software and antivirus software sections.

FAQ

Can I use one Office key on several computers?

No, a one-time Office purchase installs on only one PC or Mac. Office 2021 and 2024 can be moved to another computer you own, but you must remove it from the old one first, and moves are limited in frequency. For license terms on a specific listing, read its title and product page.

How do I check which Windows edition I need?

Your edition appears at the top of Settings > System > Activation. Buy a key for that edition: a Home copy is reinstalled as Home, and only a Pro key moves it up to Pro.

Will Windows keep updating if it isn't activated as genuine?

You will still receive critical security updates, but you will miss out on many other updates and downloads that are only for genuine copies of Windows. Activating with a valid key is how you get those genuine-only updates.

Do I install the software before or after using the key?

The order depends on the product. With Office, you redeem the key first, then install. With Avast Cleanup Premium, you install first, then activate if needed. For Windows, you can enter the key during setup or add it later in Settings. Always check the product page for specific instructions.
