Dear Tony Woolfall,
For your information, you can absolutely purchase and install the correct license to make the switch:
- Buy Directly from Microsoft
You can purchase a digital license for Windows 11 Pro from the Microsoft Store for $199.99. Once purchased, the license is linked to your Microsoft account and activates automatically.
- Upgrade via Windows Settings
If Windows 11 Home is already installed:
- Go to Settings > System > Activation.
Click “Go to Store” and choose Upgrade to Windows 11 Pro.
This upgrade typically costs $99 and does not require reinstallation.
- Third-Party Retailers Offering Discounted Licenses
If you're looking for a more budget-friendly option, reputable vendors like VIP-CDKDeals offer Windows 11 Pro licenses for around $22. You can find more details in this RedmondPie article.
Once you have the correct license key:
Go to Settings > System > Activation > Change product key.
Enter your new Windows 11 Pro key.
Windows will upgrade and activate automatically.
I hope this helps.
Best regards,
Domic Vo
