How to activate the win7 system?

            I haven't tried to install a ghost win7. I don't know if the system is installed. After the system is installed, it is not immediately usable. Because we still need to activate it, how can we activate it? Xiaobian summed up several methods to see if everyone is more interested. One kind!
1. The first one is also a convenient and quick way to activate. It is comparable to a fool-like operation. That is to use third-party software to activate. The principle is not to say much. Anyway, it can't be used anymore. Now better software activation tools such as oem7v7.2, pony activation, etc., you can find out for yourself!
2. Brush the BIOS. This method is also more commonly used in daily life. According to Xiaobian, many pre-installed versions of the professional version, the flagship version is not a real genuine system, but the OEM version of this hard brush BIOS, the role of the BIOS is Let the system recognize that you are an activation-free version to enable activation. But brushing the BIOS requires technology, so everyone should use it with caution.
3. The third is the phone activation, this method is a more formal way! This method is to follow the prompts step by step, but it is a genuine system, it is more cost-effective!
4. The fourth is to find the secret key online, Microsoft will release the secret key regularly, it should be searchable.
