I would like to know the proper sequence in activating Windows 8.1 and Office, using either Microsoft Toolkit or KMSpico. Which sequence is correct, or are both of them correct as well? 1. Install and then activate Windows 8.1. Then, install and activate Office 2013. , or: 2. Install Windows 8.1, and then Office 2013. Later, activate both of them together. Thank you for your information.
