How to Change Windows 8 Product Key

Introduction

 
In this article, we explain how to change the Windows 8 Product Key. We need to change the Product Key when the installed Product Key is invalid or the installed Product Key has expired or it may be another reason. Basically we change the Product Key from the Windows Properties by changing the Product Key option but sometimes that option has been disabled. In that condition, we use the command prompt to change the Windows Product Key.
 
If you want to activate Windows then the key used must be valid and your PC must have an internet connection.
