With regard to XP activation, I searched for many articles on the forum, discovered that there are many fuzzy views and misunderstandings on the forum, even if there are many people who have activated n times, they are not very accurate, comprehensive, comprehensive, such as people It is believed that anyway is a D version. It doesn't matter if it is activated. Some people think that the hardware can't change. If you want to upgrade, you don't dare, you think it is activated now, you will not be activated after reloading. Wait. In fact, activation technology is just a small check in XP starts or before other related software rows, to prove that we are legally owned, only. However, there are various misunderstandings. After all, for most users, it is very difficult to completely understand the principles and operational mechanisms of activation, so I have organized the activation of the activation system, which is convenient for everyone. A comprehensive, accurate understanding. Regardless of the Lenovo OEM version, the Shanghai government VLK version, or the English VOL version, or the original version, in fact, there is three options to deal with activation. Of course, there are three options after I choose XP: First, I find the activated version, two It is to install the OEM version by modifying the string in the BIOS, and the third is to install the original algorial activation. My machine is the foundation of Lenovo Zhaoyang. Initially Ltd. OEM version, I followed the English Vol version, but I was a bit regret, my serial number did not install SP2 beta, plus English The version of Chinese is still not ideal, so I have changed the VLK version of the Shanghai government version, exactly, online upgrade, etc., but the VLK version can not be used after SP2, I want the old cover in the dream. Think of this problem! So I now use the original almeditial number to activate, thank you for your order of the big tomato!
Everyone knows that Microsoft has always had a restriction on the use of the Windows operating system: a set of legally authorized Windows operating system copies can only be installed on a computer, but in fact, many people have not obey this restriction, and Activation technology is used to ensure a means of authorization can only be installed on a computer. Therefore, we have installed Windows XP for 30 days, if you want to continue using Windows XP, you must activate it. In the process of activation, the system will combine the hardware's detailed configuration and the PID (Product ID, Product ID) number generated after the operating system is installed, and then generate a string code according to Haxi algorithm (irreversible), and we need to pass this code. Tell Microsoft via the Internet or phone, Microsoft will return to another new number, use this number to successfully activate Windows XP. If it is not activated in time, Windows XP will not be available after the expiration. When you start your computer later, Windows compares the hardware devices used in the currently useful hardware device with activation. If the hardware device has a big change, we cannot continue to use our Windows XP, unless we can Contact Microsoft and reactivate it. And it is different for the purchase of the brand. The general brand is pre-installed with an OEM version of the Windows XP operating system before leaving the factory and has been successfully activated. This version of system activation is based on the BIOS. We can replace any of the hardware (except for the motherboard, in fact, the string inside the BIOS), and no need to activate again.
Everyone wants to know which hardware will be checked for activation technology? There are 10 types of graphics cards, SCSI adapters, IDE controllers (which can be said to be motherboards), network cards and their MAC addresses, memory ranges (such as 0-64MB, 64-128MB, etc.), processor type, processor serial number, hard disk, Volume sequence number (VSN, Volume Serial Number), optical drive. During installing the operating system, the installer checks the above hardware and records the corresponding data and saved on the hard disk, actually the WPA.dbl file. During future activation, this number and PID will be used to generate a 25-bit string and send it out. And if we install Windows XP integrated SP1, or install SP1 and then activate after loading, then you need to send a product key (just a string of letters entered during the installation of the operating system. And digital combinations) give Microsoft, which will shield off a wide range of leakage products that are spread on some networks, so that the products installed with these serial numbers cannot be activated. When Windows is started later, you will repeat these hardware to ensure that Windows runs on the same computer. Similarly, if we format the hard disk and reinstall Windows XP, we need to activate again, because the activation number saved on the hard disk is already there (that is, the windows / system32 / wpa.dbl file is not available), we want Reissue. So what is the accurate concept of "same computer"? If you activate the technology check this ten types of equipment, then your computer can start normally and don't need to be reactivated. In fact, as long as you can have more than seven (including seven), that activation technology will think this is still "same computer ". However, the NIC is relatively special, and the network card equipment is in this ten types of equipment. There is also something to pay attention to, I am talking in front, "as long as there is more than seven (including seven), it has not changed", not "there are three devices to change", because the activation technology is judging whether the same computer is I haven't changed how much it hasn't changed, not how many equipment changes have been seen. So if we add a CD-ROM drive in the case of an optical drive, this does not affect the judgment of the activation technology. Conversely, if we replace the existing optical drive with a new optical drive, this will be activated to think is There is a device that has changed. Therefore, if we just want to put more equipment in your computer, don't worry about activation. On the contrary, if you want to take it out, you should pay attention. If we replace some of the above ten types, it will not ask the type of device again after activation technology. So if we like it, we can change a new CD drive once a week, without having to worry too much to change too much.
What if there is too much hardware change? At the time of Windows started, most of the hardware has been changed, we can see two situations:
1. For a computer that does not install SP1, we can only start the system to security mode, and then activation technology will want us to activate Windows by phone. First we have to copy a string of 50 digits, then call the free call to Microsoft's activation center, tell the operator, and get a string of 42-bit numbers from the operator, we will enter the computer. , Then you can successfully activate our Windows.
2. If our Windows XP has installed SP1, the situation is much simpler, and the system can still start normally, and we have thirty days to react through the network. And we reload the system, temporarily do not consider using GHOST for backup, we must understand in depth if the hard disk is formatted? In fact, two data will be recorded on the hard disk: the hard disk's own serial number, and the volume sequence number (VSN) on the hard disk. The VSN data is saved in the first sector of each partition, so whenever we format this partition, the VSN record of the partition will change. If we can remember the ID of the partition before formatting the partition, then you can use the software to modify the new partition ID as the previous record, so we can answer more when the activation technology is changed. First enter the partition we want to format in command line mode, such as a D disk, then enter "VOL" directly and press Enter, write down the VSN displayed on the screen (for example: F8AA-63DE), and format the hard disk. After formatting, download a free, used to modify the software of the hard disk partition VSN: Volume ID, then run it under the command line, such as we want to modify the D disk to the F8aa-63de, Then we can enter "Volumeid D: F8AA-63DE" and enter the car, then restart immediately, and VSN has been modified (remember to be in the activation system). Another thing will make the VSN of the partition, which is the conversion of the partition file system. Whether converting the FAT file system to NTFS or use the partition magician to convert NTFS to FAT, VSN changes. So if our Windows XP is installed on the partition of the FAT file system, but we want to convert the file system to NTFS, which is best to complete before activating the system, this activation technology check the system, there is no one. Change. If we have activated the system, you can also consider using the Volume ID software mentioned earlier to modify the VSN. There are also two files that are backup WPA.DBL and WPA.BAK in the Windows / System32 folder. These two files record relevant information about product activation, and after backup, once the file is corrupt, or we override the installed system, you can restore these two backup files to return to the command line mode, avoid Activate again. However, this method is only valid in a small range. The information recorded in this file can only be satisfied with a specific Windows installation, and once the hardware on the computer changes, the effect is not possible. There are still many friends now with mobile hard drives, like I have a 20G IBM mobile hard disk, because we use mobile hard drives to store and exchange data, while operating systems are installed on fixed non-mobile hard drives, so mobile hard drives Plugging does not affect the operation of the activation technology.
Other friends have changed the motherboard, which is equal to replacing the IDE controller, and the friend who usually change the motherboard will change a faster updated processor. If there is a serial number (for example, Pentium 3 CPU) in our processor, this means we have changed three hardware (even if the processor department we replace includes built-in serial number, such as Athlon, this is the same ). If we have added memory, or the motherboard has a SCSI adapter, we will have four to five hardware changes, so we must try to ensure that the NIC does not change, so you can fight for us to fight for two hardware. If our new motherboard integrates a graphics card (usually, it will also integrate the network card), then our hardware has changed all. In this case, we don't have to replace too much hardware or you can't continue to use Windows XP. The phone activation is prepared for this situation. Of course, this is also a relatively extreme example. If we add a new hardware device, and this device is mentioned in the top ten categories, such as a hard disk, then activation technology can detect the original old hard disk when starting (even if the old hard disk is received) From the position of the disk), this is allowed. But if we format the old hard drive as a slave, the new hard disk is used as a primary disk, and the hardware Hash is calculated and sent to Microsoft is what we now use as the new hard disk ID of the primary disk. This means that this type of device has not matched, and we will change more hardware. If this change accumulates to a certain extent, we can't reactivate through the network, but to pass the phone. Therefore, from the perspective of activation technology, the best way to add hardware is to add new hardware as an "attachment." For example, if we want to add a disc drive, then we'd better put the new optical drive as a slave disk, even if necessary, to move the old optical drive to the main disc. Xpinfo is a very useful program that can tell us how the type of hardware devices have been affirmed when the system is activated during the system startup.
Everyone will not be sure, here let me give a clear answer: the authorization of the Windows XP retail version is permanent, this is to say, if we wish, we can use the product. But Microsoft also admits that the computer needs to be upgraded. In our first 120 days after we activate Windows, if our hardware devices do not change, or change in an acceptable range, we don't have to repeat the activation center, 120 days later, all records will be emptied We can use the hardware configuration at this time as a baseline resumption of changes in the statistical hardware. If we bought a new computer, we can delete Windows XP from our original computer, then install it to a new computer, but we need to reactivate it by phone, and explain our reason, unless we are in front. It is mentioned that it has been 120 days from our first activation. For some special licensed Windows products, there may be more restrictions than the above. For example, the OEM version of Windows XP is bundled with the computer we purchased, as a whole, so the version of Windows XP cannot be installed in other computer merchants. Some of the other license systems (such as educational versions) are also authorized in other different ways. These are not the problem of activation technology, but the issue of the license system, which is not discussed scope of activation technology.
If our Windows XP is installed in one of the very "famous" pirated serial numbers, it is only the serial number that cannot be activated, then we will not install SP1, and a large part of the pirated serial number installed products will not Allow access to the Windows Update website. The installed SP1 detects whether our system has been crackdown, such a system will need to be reactivated after installing SP1, or not at all, for most users, there may be many people in the so-called Simplified Chinese When you install the Simplified Chinese version of SP1, you will not be installed because the language does not match, this is a typical crack version. Typically, legitimate Windows products do not require reactivation after installing SP1. In addition, we have to know that activation technology does not send any of our private information to Microsoft, although there is a registered relevant option in activation, but this is not available with activation technology and is completely voluntary. If we use phone activation, we don't have to provide any private information. Activation technology does not activate the center through the phone or Internet contacts every day, whether the system is still in the system, is done by Windows itself when the system is started. If the hardware configuration changes too much, we need to react by phone, and Windows itself will never contact Microsoft himself unless we choose to activate our products through the network. The use of activation technology does not mean that Microsoft can close our computer or even damage our data (they can't even get any of our data at all). If the system needs we reactivate through the phone, we can also start to back up our data in safe mode. Windows products using activation technology are not a "rental", we don't need to pay for the Microsoft for two years. In contrast, we can use Windows XP to use the WINDOWS XP. Writing
