Microsoft Win8 uses OA3.0 technology to prevent traditional activation cracking

In the past, OEMs have activated Windows at the factory. Therefore, as long as the user is an OEM machine, it has already obtained the "activated" The open box experience.

Today, Windows 8 upgrades OEM Activation technology to version 3.0 to prevent traditional bypassing activation by emulating OEM BIOS information. That's right, this one must be added to the online verification mechanism.

In the new OA 3.0 activation technology, a series of new technical details are adopted. Here, for the purpose of technical discussion, we will briefly talk about the new OA 3.0 process: (specific Details are inconvenient to disclose)

1. OEMs will get some of Microsoft's product keys;

2. OEMs will inject the acquired product keys one by one when manufacturing the PC. Firmware for one PC;

3. The OEM manufacturer will generate a "computer manufacturing report" for the PC that has been manufactured and infused with the key, which will contain the ID corresponding to the key, hardware The value, and some other necessary information;

4. The OEM will deliver the computer manufacturing report to Microsoft, and Microsoft will bind the unique hardware identification information of each PC to the ID corresponding to the injected key. , write the service database of Microsoft Online Activation Service;

5. The user has purchased a new OEM PC with pre-installed genuine Win8;

6. The user starts up, after a few hours, Windows tries to silence Contact the Windows activation server over the network and successfully activate (do not interfere with the user). If you are not connected to the network, you will be prompted to activate the phone.

In fact, starting from Vista, Microsoft's activation has been upgraded to a new technical architecture level. Users who are generally consuming Windows boxed software can only be activated by a key and can no longer be replaced by local. Some files and information to bypass the activation service without affecting the health of the system. It is only a means of relaxation for the OEM PC and is activated at the factory. With the release of Windows 8, this situation has been improved, and cracking the activation of Windows 8 is difficult to achieve. Some of the activation methods previously transmitted on the Internet are nothing more than activation using a legitimate leak key, or an enterprise-level KMS server, or phone activation for activation purposes, rather than a real crack for OA 3.0. However, on the one hand, users should gradually realize the intellectual property rights of software and its intangible value, and legally purchase genuine software; on the other hand, Microsoft and large companies that have signed legal agreements with Microsoft should pay attention to protecting property and avoid similar disclosure. The event happened again.
