Can I Transfer The Windows 8 License of My Laptop to My Desktop? [duplicate]

My sister asked me to fix her Sony Vaio VPCCW23FX which she had recently installed Windows 8 Pro. However, that model is not compatible with Windows 8 and is having problems. We restored it to the pre-installed Windows 7 Home Premium. Now, I am wondering if I can use her Windows 8 license on my desktop?

Solution 1:

Yes, you can. But you can only use the license on one machine at a time.

Once the license has been added to a certain computer it will bound there. The next time you register another machine with the same code it will give you an error.

But of course if you are not using the license on the old computer anymore. You can just give Microsoft a phone call (phone activation). Where someone will walk you through to some procedures and ask you some questions then release the license allowing you to reuse it on the new computer.

But phone activations are only available on weekdays. So you can try these steps, it might work:

Press Windows key + X
Click Command Prompt (Admin)
type: slmgr.vbs -upk
Enter

This will uninstall the product key from the computer. You can now use it on another machine.
