If you’re trying to upgrade Windows 10 or 11 from Home to Pro and receive the error code 0xC004F050, it means the edition installed on your device doesn’t match the product key you’re using. This issue is common when upgrading with a Pro key on a Home edition system.
Luckily, there are two proven ways to fix this and successfully complete the upgrade using your product key from Wholsalekeys.
Option 1: Upgrade with a Generic Pro Key First, Then Use Your Purchased Key
This method forces the system to switch from Home to Pro before applying your licensed product key.
Steps to follow:
- Disconnect from the internet. Turn off Wi-Fi or unplug the Ethernet cable.
- Open Activation Settings
- Windows 10: Select the Start → Settings → Update & Security → Activation
- Windows 11: Select the Start → Settings → System → Activation
- Click “Change product key” and enter this generic Pro upgrade key: VK7JG-NPHTM-C97JM-9MPGT-3V66T
- Click Next to start the upgrade. Your PC will restart and begin upgrading from Home to Pro.
- Reconnect to the internet after the restart.
- Go back to Settings → Activation and click “Change product key” again.
- Enter your Pro product key from Wholsalekeys to complete the upgrade and activate.
This method resolves most upgrade errors, especially the 0xC004F050 error, by matching your system’s edition to your key.
Option 2: For Windows 11 – Use a Special Generic Upgrade Key
If you’re using Windows 11 Home, there’s a different generic key that triggers the upgrade.
Steps to follow:
- Go to Settings → System → Activation
- Click Change product key
- Enter this Windows 11 Pro upgrade key: NW6C2-QMPVW-D7KKK-3GKT6-VCFB2
- If you get an error, restart your PC
- After rebooting, go back to the same settings
- Enter your licensed Pro key from Wholsalekeys to finalize the upgrade
This path works best for users on Windows 11 who see the upgrade block with a 0xC004F050 error.
If the Upgrade Still Fails
Sometimes, system issues can prevent a successful edition upgrade. Here’s how to handle it:
Option 1: Create a New Local Windows User Profile
A corrupted user profile can interfere with upgrades. Create a new one and try again:
Create a new Windows user account
Option 2: Perform a Clean Install Using Installation Media
