2. There are many such tools, such as kms win7 activation tool, Pony activation tool, windows loader and so on.
3. Most of these tools are realized through the following principles.
(A) "bristle brush" activation
In order to reduce the activation load of the operating system, Microsoft and PC manufacturers have implemented the "SLIC 2. 1 activation mechanism" on the brand machine, which is different from networking activation: when the operating system is started, it will automatically scan the public key and logo in the BIOS (slic2.1), as well as the "OEM key" and "OEM certificate" in the system. If the three are completely consistent and verified, the system will be recognized as an OEM version without activation. This method can be used by about 98% of computers except that the motherboard BIOS of a few computers is not compatible with "SLIC 2. 1".
(b) "soft change" activation
Same as Hard Brush activation. The difference is that by running the "soft change" cracking tool, a priority plug-in will be injected into the root directory of drive C when the system is started. The function of this priority plug-in is to organically combine "SLIC 2. 1" with the "mapping" of the motherboard BIOS in memory, and realize "activation-free" of the operating system like a brand-name machine.
This method can be used by about 98% of computers except that the motherboard BIOS of a few computers is not compatible with "SLIC 2. 1".
(3) "telephone" activation
The original intention of Microsoft to set up "telephone" activation is to provide "activation ID" service for genuine users who can't use push-button networking activation due to hardware changes (note: when installing the system networking activation for the first time, the "25-bit string recording the main hardware information" will be sent to Microsoft for filing). eight
100% success as long as the operation is correct.
(4) "MAK" activation
This is one of two ways for Microsoft to authorize large customers to activate in bulk. The principle is simple: the input key is verified by Microsoft activation server to activate the system. 100% is successful as long as the "MAK" key has the remaining activation times.
(5) "KMS" activation
This is one of two ways for Microsoft to authorize large customers to activate in bulk. Major customers are activated in stages through the "KMS" server authorized by Microsoft (the cycle is 180 days). It all depends on the "opening" and effective operation of the "KMS" server (actually privately set).
