Everyone knows that Microsoft has always had a restriction on the license of Windows operating system: one set is legal. Authorized copies of the Windows operating system can only be installed on one computer, but in fact many people do not comply with this restriction, and activation technology is used to ensure that an authorization can only be installed on a computer. means. Therefore, within 30 days of installing Windows XP, we must activate it if we want to continue using Windows XP. In the process of activation, the system will combine the detailed configuration of the hardware and the PID (Product ID) number generated after installing the operating system, and then generate a string of codes according to the hash algorithm, and we need to pass this code through the Internet or The phone tells Microsoft that Microsoft will return another new number to us and use this number to successfully activate Windows XP.

If not activated in time, Windows XP will not be available after expiration. When you start your computer later, Windows will compare the hardware device you are currently using with the hardware device you used to activate. If the hardware device changes a lot, we can't continue to use our Windows XP unless we can Contact Microsoft and reactivate. The situation is different for the brand machine purchased.

What is product activation?

Microsoft Product Activation Service is a software product designed to verify Anti-non-genuine technology with legal licenses.

The activation technology will check which kinds of hardware

The activation technology will check 10 kinds of hardware, namely:

graphics card, SCSI adapter, IDE controller, network card and MAC address, memory range, processor type, processor serial number, hard disk, volume serial number, optical drive.

During the installation of the operating system, the installer will check the above hardware, and record the corresponding data, and save it on the hard disk, in fact, is the WPA.dbl file. In the later activation process, this number and PID will be used to generate a 25-bit string and send it out. And if we install Windows XP with SP1 integrated, or install SP1 and then activate it after installing XP, then we need to send the product key to Microsoft during the activation process, which will shield some networks from spreading widely. The product key leaked out so that products installed with these serial numbers cannot be activated. In the future, each time Windows starts, it will check the hardware repeatedly to ensure that Windows is running on the same computer. Similarly, if we format the hard drive and reinstall Windows XP, we need to activate it again, because the activation number saved on the hard disk is gone (that is, the Windowssystem32WPA.dbl file is missing), we have to re-acquire.
