How to Upgrade Windows 11 Home to Pro (Step-by-Step)

You can upgrade Windows 11 Home to Pro without reinstalling Windows or losing your files. This is done through the Activation settings on your PC, using a Windows 11 Pro product key, or by buying a Pro license through the option offered on the same screen.

Quick steps

1. Open Settings and go to System > Activation.
2. Select Change product key, or the option shown for changing your edition of Windows.
3. Enter your Windows 11 Pro product key, or choose to buy a Pro license if you don’t already have one.
4. Follow the on-screen prompts to confirm the change, then restart your PC if asked.

Before you start

A few things to check before you begin:

• You need a genuine Windows 11 Pro product key, or a Microsoft account linked to a Pro license. If you don’t have a key yet, Windows gives you the option to buy one from the Activation screen.
• Your PC is already running Windows 11 Home, so it already meets the baseline requirements for Windows 11. Moving to Pro is an edition change, not a new installation, so you generally don’t need to recheck hardware requirements just for this.
• Back up anything important first. An edition upgrade is intended to keep your files and apps in place, but it’s still good practice to have a backup before any change that involves activation or a restart.
• Make sure you’re signed in with an administrator account, since changing the product key requires admin rights.
• Have a stable internet connection ready, since activation needs to communicate with Microsoft’s servers.

Upgrade using Settings (most common method)

This is the standard way to move from Home to Pro on a Windows 11 PC, whether you already own a Pro key or need to buy one.

1. Click Start and open Settings.
2. Go to System, then scroll down and select Activation.
3. Look for the section related to changing your Windows edition.
4. Select Change product key.
5. Type in your Windows 11 Pro product key when prompted and continue.
6. Windows checks the key, applies the new edition, and may ask you to restart your PC to finish.
7. Once your PC restarts, go back to Settings > System > Activation to confirm it now shows Windows 11 Pro with an activated status.

Upgrade by buying a Pro license through Windows

If you don’t already have a product key, you don’t need to track one down separately. Windows offers a way to buy the upgrade from the same Activation screen.

1. Open Settings > System > Activation.
2. Select the option to upgrade your edition, which takes you to the purchase flow.
3. Complete the purchase using your Microsoft account and preferred payment method.
4. Once the purchase goes through, Windows applies the Pro license to your device.
5. Restart your PC if prompted, then check Activation again to confirm you’re now on Windows 11 Pro.

Because this method is tied to your Microsoft account, it can also make it easier to confirm your Pro license is active if you sign in again on the same device later.

Upgrade on a work or school managed device

If your PC is managed by an organization, for example through a device management tool, you may not see an option to change the product key yourself, or the edition may already be set centrally by your IT team. In that case:

1. Check Settings > System > Activation to see your current edition and whether a product key option is available to you.
2. If the option is missing or unavailable, contact your IT administrator rather than trying to buy a consumer Pro license yourself.
3. Your organization may apply Pro, or a higher edition, through its own management policies instead of a manual key entry on your device.

If it doesn’t work

The product key is rejected or won’t activate

Double-check that you’re entering a Windows 11 Pro key, not a Home, Enterprise, or Windows 10 key, since these aren’t interchangeable. Also confirm there are no typos, since product keys mix letters and numbers that are easy to mistype. If the key still won’t activate, try again after restarting your PC and confirming you have an active internet connection.

Activation shows an error after upgrading

Restart your PC and check Settings > System > Activation again. Activation can sometimes take a few minutes to sync with Microsoft’s servers, especially right after a purchase. If an error persists, look for a troubleshooting option on the Activation page and follow the prompts it gives you.

You don’t see the “Change product key” option

This usually happens on managed or enterprise-enrolled devices, where edition changes are controlled by an organization’s IT policies. If that’s the case, your administrator will need to apply the Pro license on your behalf rather than you doing it through Settings.

Your PC doesn’t seem to meet Windows 11 requirements

If your device is already running Windows 11 Home, it already meets Microsoft’s minimum requirements for Windows 11. An edition upgrade from Home to Pro is a licensing and feature change, not a new installation, so this issue is unlikely to come up during the process itself.

Frequently asked questions

Do I need to reinstall Windows to upgrade from Home to Pro?

No. Upgrading editions through the Activation settings keeps your files, apps, and most settings in place. A reinstall isn’t necessary for a Home to Pro edition change.

Will I lose my files when I upgrade to Windows 11 Pro?

Your personal files and installed apps are intended to remain in place during the edition upgrade, since it’s a license and feature change rather than a fresh install. That said, it’s still good practice to back up your important files before any system-level change.

Can I switch back from Pro to Home later?

The edition upgrade option in Settings is designed to move you from Home to Pro, not the other way around through the same screen. There isn’t a simple built-in downgrade path from Pro back to Home using that product key screen, so if you need to return to Home you should check Microsoft’s current guidance for your specific situation before making any changes.

What’s the difference between Windows 11 Home and Pro?

Windows 11 Pro adds features aimed at business and power users, such as additional management, security, and networking capabilities not included in Home. If you rely on tools typically used in managed or work environments, Pro is usually the edition you need.

How much does the Windows 11 Pro upgrade cost?

Pricing for the Pro upgrade is set by Microsoft and shown directly at checkout when you choose to buy the license through the Activation settings, so it’s best to check the current price there rather than relying on older figures.
