How do I activate Win7 through the hard brush bios? The method of activating the Win7 system without activating code with a hard brush

The first thing you need to remind users is that if you feel the hardware knowledge, especially the BIOS is slightly missing, or do not imitate the operation of this article, in the brush BIOS upgrade process to do the most possible not to make mistakes. Although most gigabyte and ASUS motherboards currently on the market have a way to automatically restore the BIOS, but the premise is that your BIOS has been backed up or downloaded from the official download of the newer BIOS and engraved disk (CD or floppy drive-depending on the motherboard, you should first look at their own motherboard instructions), Once the motherboard into a brick and save the way, otherwise you can only return to the factory or find maintenance agencies, so generally do not recommend in the notebook test.

Note: In addition to very individual computer motherboard BIOS and "SLIC 2.1" is not compatible with, about 98% of the computer can use this method hard brush (or soft change) activation.

Note: Before the hard brush activates windows7, please read this tutorial thoroughly to digest each knowledge point, and any consequences of this tutorial are irrelevant to the author.

The hard brush contains "SLIC 2.1" BIOS is not mysterious, but must be cautious. Special attention should be paid to: pre-backup BIOS safekeeping, it is recommended to understand the first good grasp, and then enter the practice operation.

The tool kit required for the hard brushes:

Perfect to activate the Windows 7 flagship, you need three things:

To activate Windows 7 by using the "Hard Brush" method:

One. BIOS containing "SLIC 2.1"

Two. OEM Certificate

Three. OEM key.

(In this special note three: first, different motherboard BIOS brand is different; second, the different brand machine "OEM certificate" is different; third, different versions of the "OEM key" is different. ）

slic table: Microsoft from Vista started using the Slic table to activate the OEM Windows,slic table exists in the BIOS, and the main part has two big chunks: PubKey and Marker,pubkey to match the OEM Certificate in the system. Marker determines the version of Windows that slic can activate. Version 2.0 marker only activates the vista,2.1 version marker can activate Windows 7 and (supposedly most) VISTA.

Slic full name is the software Licensing Internal code, that is, the software license internal codes. Microsoft has tried to control users ' illegal use of the OEM version through Slic. Starting with Vista systems, the SLP (system-locked Preinstallation) verification technology was upgraded to 2.0. The main part is the process of signing the information with the key. So the validation process becomes more complex, so that the verification information is forged.

This verification process needs to be supported by extending a dedicated SLIC table in the ACPI of the BIOS.

In the Windows 7 Series, SLP 2.1 technology was used, in which Microsoft did not make major changes to SLP technology, still using slic tables, and the structure of the Slic table was unchanged. It just turns the marker version to 2.1, which, of course, causes a change in the digital signature in the marker. It is compatible with 2.0. So using Slic 2.1 can also be used for Vista activation.

SLIC2.0:

SLIC2.1:

OEM KEY:

The OEM serial number for Windows 7 is divided into two major categories--OEM:SLP key, OEM:NONSLP key, and Oem:coa key.

OEM:SLP key: Brand computer pre-installed system use of OEM Key, general Microsoft each version of Windows will only give each OEM manufacturer a OEM:SLP key, this OEM manufacturer all the same version of the brand machine factory pre-installed system use a key. SLP do not need to network to Microsoft server activation, only need the computer BIOS has SLIC2.1, the system imported and SLIC2.1 table PubKey matching certificate, SLP key and you installed Windows7 match, you can automatically activate. and SLP key do not worry will be sealed, because a large number of brand-name machine users are using this key, sealed words will appear serious manslaughter (this article we will introduce this method of hard brush BIOS activation Win7)

OEM:NONSLP key: Some small OEM vendors that do not use the SLIC activation mechanism are using this key, which, like RTL key, requires networking activation.

Oem:coa key: Brand computer, notebook lower right corner will have a COA label, there is a key, this key is Oem:coa key, this key is the OEM manufacturer to you to reload the system used, and the ordinary RTL Key activation mechanism, Need to be networked to Microsoft Activation Server activation, of course you can also telephone contact Microsoft activation.

The above is the small compilation of the win7 system without activation code through the hard brush BIOS activation method, we can refer to, I hope it will help.
