"Win8 OEM new activation mode: each computer's key is unique" suddenly let Win8 users get a tight heart, Microsoft this OA (OEM Activation) 3.0 Can you stop piracy? Windows 8 will adopt the new activation technology OA 3.0, which was announced by Microsoft at Computex 2011 (June last year). As we all know, Windows 7 is equipped with OA 2.1 technology, and Vista is equipped with OA 2.0. Win8 with OA 3.0 can be said to be "unexpected".
So, what is the principle of OA3.0, as a user, what do we need to know? Let's review an old article "Win8 OEM Activation Mechanism OA (OEM Activation) 3.0 Principles."
OA3.0:
It mainly introduces a set of 5X5 digital serial numbers contained in OA3.0, a hardware hash sequence, a GML label and a general process.
Noun explanation:
COA:Certificate Of Authenticity, Microsoft's genuine logo on the machine, including anti-counterfeiting and 5x5 serial number. The current activation mode is used.
5X5 digital serial number:
OA3.0 changed from the previous COA way to the label to digital data mode. Includes 3 types of keys: standard key, test key, and repair key.
The standard key is used for shipping and needs to be purchased from Microsoft.
Test key is used for testing and is provided free of charge.
The repair key is used for bad board repair, the number of restrictions is free, and the discount after the quantity is exceeded.
Hardware hash:
When the system is activated and each time the system is entered, a set of 128-bit hardware hash data is generated according to the hardware configuration, which is used to compare with Microsoft saved. Work with the serial number to activate the system.
Hardware hash is related to hardware configuration. The main board has the biggest impact, and the peripherals have little influence. The specific configuration impact is being determined.
GML: Genuine Microsoft Label, Microsoft Genuine Label,
1) is only used to identify genuine, and has no other meaning.
2) Anti-counterfeiting design without COA complex
3) WHQL label and GML label are combined.
4) Need to purchase from Label list.
The following Microsoft referred to as MS, Hardware is referred to as HW.
Main Process:
1. OEM/ODM vendors (either factories or companies) offer purchases to Microsoft.
2. MS billing& delivery (should be the payment phase).
3. OEMs get the keys through WEB or proprietary channels (B2B).
4. Factory side:
a) The key that will be obtained is the key file of the key with the OA3.0 tool, and the Insert Product key into BiOS.
b) Use the OA3.0 tool to generate HW hashes based on the bench configuration calculations and store them in an .XML file.
c) Adhere GML.
5. Send the CBR (Computer Build report) generated by the OA3.0 serial number and the HW hash generated by each machine hardware to the MS.
6. After receiving the CBR, the MS is included in the MS server. And give OEM feedback based on the received serial number and HW Hash, if the OEM has an error, it will be pointed out.
7. The user activates the network connection for the first time (by phone if there is no network).
a) After the first boot, the serial number and the HW Hash generated by the local machine will be sent to the MS in the background.
b) The MS compares the serial number and the locally calculated HW hash with the previous OEM report's CBR to determine whether to activate the system.
c) Activate the system if the alignment is consistent. And send the HW hash to the user's hard drive and save.
d) After each boot, the user will generate a set of HW hashes, and compare them with the saved in the hard disk.
e) If you reinstall the system, run it again according to the new activation process.
Maintenance process:
After replacing the motherboard, you need to brush in the repair key. (The repair key CBR does not need to be sent to the MS in advance). After the first boot, the repair key and HW hash will be sent to the MS for registration. Save the hard drive to the hard drive. After each boot comparison.
Note:
1. It can only be used on the next generation OS. The current system cannot be used and cannot be backward compatible. Server and embedded aspects are not included in OA 3.0.
2. OA3.0 is not the only way to activate, there is a PKEA (Product Key Entry Activation) method, which is a manual input sequence.
3. How to buy: Purchase digital serial number from Microsoft and purchase label from Label provider.
It takes about 4 hours from purchase to availability, not a few days before. However, it is also necessary to leave a sufficient amount of time in production.
4. In terms of custody: the digital serial number needs to be protected, and it needs to be controlled and controlled to prevent misuse and misuse.
5. There is no time limit after Key purchase, but 10% return per month is allowed.
