If you already have the product key for Windows 8 Pro, when you get the replacement with Windows 8, just do the following:


Press Windows key + X

Click System

Under Windows Edition, click the link:

Get more features with a new edition of Windows

Click the 'I already have a product key link'

Enter your product key and you will be upgraded to Pro.



Reactivation by telephone might be required:

1. Press Windows key + X then click Run, then type: slui.exe 4

2. Next press the 'ENTER' key

3. Select your 'Country' from the list.

4. Choose the 'Phone Activation' option.

5. Stay on the phone (do not select/press any options) and wait for a person to help you with activation.

6. Explain your problem clearly to the support person.
