Well, I'll tell you the activation principle and you'll know. Windows 7 has two verification activation processes, corresponding to OEM system and retail version system respectively.

For the OEM system, when the system starts, it will first check whether the key you use, that is, the professional version key you use, is an OEM key (Microsoft has its own number or number segment for major PC manufacturers), and if it is, it will proceed to the next verification, that is, this is the beginning of the verification process of SLIC2. 1 (SLIC is a special code in the computer BIOS, and only OEM machines have this code) to verify the SLIC certificate. Once the certificate and signature in your SLIC code are verified, the certificate and signature in the system are Lenovo, OK, activated, and this process is called OEM verification.

Another way, call or network activation. Imagine if we bought a compatible or brand-name machine without Windows 7 pre-installed, there would be no SLIC2. 1 code in the BIOS. At this time, if you buy the retail version of Windows 7 through regular channels, how can you verify the activation? At this time, the system will implement such a mechanism. First, see if your key or key is an OEM number segment. As soon as the system checks, oh ~ ~ you are the key of the retail version, then the system will no longer check whether your BIOS SLIC code or certificate matches the system, and immediately jump out and prompt: "Please activate". At this time, you must choose to activate by phone or network.

Your question is easy to explain. The key you used is circulated on the Internet, but for some reasons, such as too wide circulation, this number has been blacklisted in Microsoft's system, that is, blocked. Before being blocked, the system verifies that this key is the key of OEM, and the OEM verification process has been carried out, which can pass smoothly. After being blocked, the system is regarded as a non-OEM key and needs to activate the network and telephone. Of course, you can't get excited.

Only by knowing the root cause can we find the corresponding method. Now you just need to find a Lenovo OEM key circulating on the Internet, and use the command:

SLMGR。 VBS-ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

By importing this key, you can return to the OEM authentication method.

At this time, you may ask, if the original blocked key is the OEM key released by Lenovo, wouldn't it be that many users who use real Lenovo brand machines and pre-install the flagship system like you will be blocked? In fact, I have long thought that the shielding key you used was given to Lenovo in advance before Win 7 was officially released on June 23, 2009. Used for Lenovo to produce batch machines in case computers with Win 7 could be launched at that time, but this key flowed out due to negligence. However, at that time, Lenovo's pre-installed Win 7 system had not officially started to be sold on June 23, 2009. Later, the key was completely changed, so the pre-stream key was blocked after living online for a period of time.

Now you go online to find a real Lenovo flagship key, a lot, Baidu or Google. It can be activated perfectly.

In addition, I personally suggest not to use the so-called "magic key", whether it is sealed or not depends on Microsoft. The reason why the key to God is God is that Microsoft is releasing water in order to occupy the market. When there is no need to drain water, I will seal you up. Only the OEM key with SLIC 2. 1 authentication mode is the lifetime unshielded activation mode. There is a simple reason. Lenovo users who actually bought the pre-installed flagship system will not be blocked because you are blocked, and it is impossible for every such normal user to change the key.

E-mail me and I'll send you Lenovo key.
