How do I Transfer Win 8 activation from one PC to another?

How do I transfer a Win 8 Pro (upgrade) activation from one system to another? I tried Win 8 on an old PC and when I was happy with it, I uninstalled it from there and then installed it on my new PC. Although Windows accepted my product key during the install, it would not allow me to activate with it saying it had already been activated on another machine. Can you help?

You will first need to remove it from the computer it is currently installed, this means you will need format the drive or reinstall the previous version of Windows. You are then free to use the key on the other computer. You might need to reactivate by telephone:

You can download it from there and use your product key to upgrade:





Phone activation:

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.
