UPGRADE MY OS FROM WIN 11 HOME SINGLE LANGUAGE TO WIN 11 PRO

Sign in to Windows and Microsoft Store with the Microsoft account used to purchase the Windows 11 Pro upgrade, open the purchased upgrade in Microsoft Store, and select Install.

Complete the upgrade

1. Save your work and close open applications.
2. Open Microsoft Store and verify that its profile icon shows the account used for the purchase.
3. Open the purchased Windows 11 Pro upgrade and select Install.
4. Allow Windows to complete the edition upgrade, then restart the computer when prompted.
5. After restarting, connect to the internet and open: Start → Settings → System → Activation
6. Confirm that:
   • Edition shows Windows 11 Pro.
   • Activation state shows that Windows is activated.

A Pro upgrade purchased through the Microsoft Store app uses a digital license associated with the purchasing Microsoft account; activation should occur after the PC is online and signed in with that account.^1^

If the Store installation is missing, stuck, or does not start

Use the following edition-change procedure:

1. Disconnect the PC completely from the internet.
2. Open Settings → System → Activation.
3. Next to Change product key, select Change.
4. Enter this Microsoft generic Windows 11 Pro edition key: VK7JG-NPHTM-C97JM-9MPGT-3V66T
5. Continue with the upgrade and restart the PC.
6. Reconnect to the internet and sign in with the Microsoft account used for the Store purchase.
7. Return to Settings → System → Activation and check that Windows 11 Pro is activated.^2^

The generic key only changes the installed edition to Pro; it is not an activation license. Your purchased Microsoft Store digital license performs activation afterward.

If Windows 11 Pro is installed but not activated

If the Activation page displays Troubleshoot, Windows is currently unactivated:

1. Open Settings → System → Activation → Troubleshoot.
2. If offered, select Upgrade to Windows 11 Pro.
3. Select Start upgrade and wait for completion.
4. If Pro is already installed, select Activate Windows → Activate instead.

The troubleshooter requires an administrator account, and its Troubleshoot option appears only while Windows is not activated.^3^

If activation still fails, use Microsoft customer support from the same activation-troubleshooter page and keep the Store purchase confirmation available.
