How to Upgrade Windows 11 Home to Pro: Step-by-Step Guide
Share
You can upgrade Windows 11 Home to Windows 11 Pro without reinstalling Windows and without losing your files or apps. The upgrade is done from Settings with a valid Windows 11 Pro product key and usually takes a few minutes. This guide walks through the steps, what you gain and how to fix common problems.
The Short Answer
- Open Settings > System > Activation.
- Select Change product key and enter a valid Windows 11 Pro key.
- Follow the prompts, let the PC restart, and wait for the upgrade to finish.
Why Upgrade From Home to Pro?
Windows 11 Home covers everyday use. Pro adds tools aimed at work, security and advanced users:
- BitLocker drive encryption management
- Remote Desktop host, so you can connect to your PC from another device
- Hyper-V virtual machines and Windows Sandbox for safe testing
- Group Policy and the ability to join a work domain or Microsoft Entra ID
- Support for more memory and two processor sockets

Before You Start
- Back up important files. The upgrade keeps your data, but a backup is always sensible.
- Connect to the internet. Windows may need to verify the key and download files.
- Install pending Windows updates and restart first.
- Have a valid Windows 11 Pro key ready. A Home key will not upgrade your PC, and the key must match your edition type, so a Home N PC needs a Pro N key. Our Windows 11 Home to Pro Upgrade Key is made for PCs that already run Windows 11 Home.
- Plug in a laptop so it does not run out of battery mid-upgrade.
Step-by-Step: Upgrade With a Product Key
- Open Settings and go to System > Activation.
- Expand Upgrade your edition of Windows.
- Select Change next to Change product key.
- Enter your 25-character Windows 11 Pro product key and select Next.
- Select Start to begin the upgrade. Save your work first.
- Wait while Windows applies the upgrade. Your PC will restart one or more times.
- Sign in and return to Settings > System > Activation to confirm it shows Windows 11 Pro and that Windows is activated.
Tip: sign in with a Microsoft account after upgrading. This links your digital license to the account and can make reactivation easier if you change hardware.
Common Problems and Fixes
"This key can't be used" or an invalid key message
Check the key for typing errors, and make sure it is a Windows 11 Pro key rather than a Home key. If your PC runs an N edition, you need the matching N key.
The upgrade option is missing or does nothing
Install all Windows updates, restart and try again. Make sure you are on Windows 11 Home and connected to the internet.
Windows says it is not activated after the upgrade
