Activating Windows 10
Types of Windows 8 activation
There are two methods for activating Windows 8: Windows Product Activation and OEM Activation 3.0. Windows Product Activation (WPA) sends an installation ID number to Microsoft before Windows is verified, and then activated. WPA involves two numbers. One is an installation ID (generated by entering a Windows 8 product key) that the computer owner submits to Microsoft, either over the Internet or by phone. The second is a confirmation ID, assigned by Microsoft, which is used to activate the operating system’s software. This method is used when upgrading or installing Windows 8 from the disc (not HP System Recovery).
OEM Activation 3.0 (OA3) takes place at the factory. A digital product key (DPK) is installed on the motherboard BIOS during the manufacturing process. Windows 8 will activate automatically the first time the computer is connected to the Internet. With OA3-activated systems, most of the computer’s hardware can be replaced without the need to reactivate the software through Microsoft.
