When software manufacturers produce their own products, they will input a serial number (registration number /key) for each product, such as "KH2J9-PC326-T4D4-396V-TVPB by", and users have to pass this serial number (registration number /key) to install and use it. Just like buying a lock with a lock and a key, it can't be opened without a key.
Question 2: What is a product key? Where is it? It is a combination of a number and a letter on the package. For example, to register your product, you need to enter this thing.
Question 3: What is a windows product key? Hello!
The product key is the proof of product authorization, and it is a random number generated according to a certain algorithm (such as elliptic algorithm). When the user inputs the key, the product will judge whether it conforms to the corresponding algorithm according to the key input, thus confirming the user's identity and usage rights.
brief introduction
Unlike some encryption technologies that use the same key to encrypt and decrypt data, public key encryption technology uses a pair of matching keys to encrypt and decrypt data. Each key performs one-way data processing, and the function of each key is just the opposite of the other. When one key is used for encryption, the other key is used for decryption. The public key is made public by its owner, while the private key must be kept secret. In order to send a confidential message, the sender must use the public key of the receiver to encrypt the data. Once encrypted, only the receiver can decrypt it with his own private key. Conversely, users can also process data with their own private keys. In other words, the key pair can work in any direction. This provides the basis for digital signature. If the user wants to process data with his own private key, others can process data with the public key provided by him. Because only the owner knows the private key, the processed message forms an electronic signature-a file that no one else can generate. A digital certificate contains public key information to confirm the identity of the user who owns the key pair.
Understand the product key
A product key is required for all versions, languages and 32-bit and 64-bit versions of the Windows Server 2003 series. The product key is a 25-character alphanumeric string in 5 groups of 5 characters separated by dashes. You must enter the product key during the installation process to complete the installation. (If the computer is obtained from the original equipment manufacturer, the manufacturer may have pre-configured the product key of the Windows Server 2003 operating system pre-installed on the computer).
The Windows Server 2003 operating system requires you to ensure that the product key is always available and put it in a safe place. If you need to reinstall the operating system, you must only use the product key assigned to a specific Windows Server 2003 operating system installation. If you try to use the product key of other Microsoft products, test programs or other versions of Windows Server 2003 operating system, the installation will fail.
Each product key can only be used to install software on a specific number of unique computers. The actual number of computers depends on the End User License Agreement (EULA). If you receive multiple product keys, you need to keep track of the product keys used when installing the Windows Server 2003 operating system on each computer.
Please ask questions if you have any questions, and adopt them if you have no questions. Thank you Baidu bosom friend: Jin Ge's blue horse
Question 4: What is a computer product key? If you don't know what to do, who installed your computer? The software has expired and is not registered. Search online (Baidu) for a serial number. XVQC3-KY4GQ-DQFQP-JC624-QJRMJ
Question 5: What does the product key mean? . . Do you have to do it? If you don't care, win8 won't work. Activate it.
Question What is the product key of Windows Ultimate? About activation:
1, hard-flash BIOS. 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 match completely and the verification is consistent, the system will be recognized as OEM version and no activation is required. This is a so-called "perfect" activation method, but it has certain risks; But if you operate well and don't mess around, there will generally be no problem. Compared with other activation methods, fewer users use this method. By "hard brush" activation, your system is basically the same as a brand machine. Although it is applicable to any computer and any BIOS in theory, there will always be a gap between theory and practice. This gap first stems from the user's understanding of BIOS and its SLIC 2. 1, followed by the matching of "hard brush" tools and the shielding of SLIC 2. 1 by some BIOS. This method is not recommended for beginners. Before deciding to brush hard, they must search for relevant experience on the internet and forums and make preparations for full implementation.
2. Soft activation. By running the "soft change" cracking tool, a priority plug-in will be injected into the root directory of drive C with the system starting. 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 an OEM brand machine. Many users use soft activation, which is harmless to computers. But in fact, Microsoft knows all about "soft change" cracking activation, and the reason why it acquiesces in unlimited activation is nothing more than a strategy to expand market share. There are many soft activation tools, such as WIN7_Activation, oem7v7.2, PCSKYS_Windows7Loader, all versions of Windows 7 plus Patch 7 Final of Orbit 30, and so on.
It should be noted that whether it is "hard brush" or "soft change", * * * has the same thing: the activation mechanism is exactly the same; The difference is: the way used is different. If you ask which method is better, the short answer is: "hard brush" is more thorough; The operation of "soft change" is simpler.
3. Mobile phone activation. For example, a popular Windows 7 flagship version of "activation key"-TFP9y-VCY3P-VVH3t-8XCC-MF4YK, after installing Windows 7 flagship version, under the premise of ensuring smooth network, do the following operations: right-click the desktop "Computer"/"Properties"/"Change product key"/"Activate by using automatic telephone system"/type. After Microsoft's "activation server" verification, there are only two final results: First, it is very lucky to pass the "Microsoft genuine key verification" and directly activate the operating system. Second, the first interface will pop up. Even so, as long as you have a certain degree of "patience" and "meticulous", successful activation is still very easy.
4. The legendary "God Key". You can activate the "God Key" of Windows 7 Ultimate without cracking it. The first "magic key": TFP9Y-VCY3P-VVH3T-8XCC-MF4YK; The second "magic key": KH2J9-PC326-T4D4-396V-TVPBy. These two "magic keys" are derived from Microsoft's "free gift" to Windows 7 users, and there is no limit on the number of times "spreading rumors" can be activated (as for when to stop using them, it depends entirely on Microsoft's decision). The two "magic keys" released by Microsoft again are similar to those provided before: after installing the 32-bit (x86)/64-bit (x64) flagship version of Windows 7 in Chinese and English, on the premise of ensuring the smooth network: First, if you are lucky, you can realize one-click direct activation; Second, if you are unlucky, 100% can be activated by phone. Now we offer two latest "magic keys": the third "magic key": 236tw-x778t-8mv9f-937gt-qvkbb; The fourth "God Key": 87VT2-> >;

2. Use the activation tool to crack activation.
1) win7activation v1.7 (recommended, activation succeeded by 90+%~) or more.
2)Windows7_Loader_v3.27
3)SK_Patch_v 1_R2_Final
4)nt6-oem-loader-v3
5)oem7Y
(The download address of the specific activation tool is omitted, because you know)
Friendly reminder: At present, more than 99% of the so-called keys are invalid, so using activation tools to crack activation is the most time-saving and labor-saving method.
How to verify whether Windows 7 is activated:
1, the simplest thing is to right-click my computer and view the properties.
2、Win+R = = = & gt； Enter slmgr.vbs -dlv (recommended, this command has the most complete information).
3、Win+R = = = & gt； Enter slmgr.vbs -dli.
4、Win+R = = = & gt； Enter slmgr.vbs -xpr.
5、Win+R = = = & gt； Enter Winver
Free use of Windows7 1 year.
Even if you are not an official tester of Microsoft, you don't need to look around for the activation code of Windows 7. In addition to the installation key provided by the government, we can also use Windows 7 1 year for free in other ways.
Initially, Windows 7 offered a 30-day trial period. However, before the 30-day deadline is coming, we can use the command "slmgr.vbs-rational" to extend the probation period by 30 days. Although the official document stipulates that this command can only be reused for 3 times, it means that * * * can experience 120 days for free, and then it will not be used again. In fact, the command "slmgr.vbs -rearm" can be reused as long as a key value is modified in the registry. Please open the registry editor, navigate to "HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ current version \ software protection platform", find "SkipRearm" in the right pane, and modify its key value to "1" so as to use the "slmgr.vbs -rearm" command again in the future. This key value can be modified 8 times, which means that we can reuse the command "slmgr.vbs -rearm" 8 times.
