How does a software identify the computer on which it is installed?
A computer with a processor, disk, etc. We buy unit operating system software, office etc., to install it. But you can not install on another computer. How the software identify its "home" then? If change the hard drive while I reinstall the same software or I can not?
Each network interface card has its own MAC addresses. All equipment components have a ROM that stores the product serial number. Thus, the mother, so they have a serial number that can Retriver. OS stores all these details during the installation and during activation. The serial number is responsible protectiting software piracy and activation determine the operating system of origin. The threshold activation has some limitations. Windows Product Activation (WPA) controls 10 details of the display adapter hardware IDE SCSI Adapter (in fact the motherboard) Network card (NIC) and the MAC address of RAM Amount Range (ie 0-64Mo, 64-128, etc.) Processor Type Processor Serial Number Hard device Hard Drive Volume Serial Number (VSN) CD-ROM / CD-RW / DVD-ROM, which calculates and stores data based on the first device of each type to be found during installation, and shops this number on your hard drive. Initially, this letter is sent to Microsoft as the automatic numbering, along with the product number of the 25 unique product key character used in the Windows settings. The equipment is checked at each Windows start time to ensure you're always on the same machine. Moreover, if then perform a full format and reinstall Windows, the Microsoft Activation Center will contact again because the information held in the own machine (the number is written on the hard drive) have been destroyed by reformatting the hard disk. If your hardware is basically the same, this will be through a call automatically without you needing to talk to anyone. What is "essentially the same mean? WPA calls" voice "of each of these ten categories: "Is this the same device again, or never was? Seven votes for Yes means that all is well - and a network card, this principle has not changed, has three votes, yes! Card minor, such as sound cards, do not enter the mix of everything. If you keep the motherboard with the same amount of RAM and processor, and an always present cheap NIC (available for $ 10 or less) you can change everything else as much as you want. If you change the device in any category, which has lost that Yes vote - but do not lose by not later if you make changes in this new category. For example, you can install a new video card every month, as long as you want. Note that it seems that if you start with a reduced mobility device (off - not removed) that the device is not on the list -- so if, for example, disable a network connection that uses the network adapter, then restarting, you can lose your three votes and find a new activation necessary. If you do these things, to the point 3 in Gone with the format of a hard drive? below, and restore the files in question, once again the NIC is in service. What if I make many changes? If Windows is started, are not necessary seven votes Yes, the system will be in the original version of Windows XP, but only start in safe mode. You will be asked to reactivate by a phone call to Microsoft. You'll have to write 50 numbers, activation call center in a number free phone to be delivered to you, read and check the number you have registered - and explain the circumstances. In return, a man receives 42-digit for the type In This reactivate your copy of Windows. This is easier if you have installed Windows XP Service Pack 1: The system will continue to start normally for three days during which you can contact the activation center via the network. If additional changes removed, or if 120 days have elapsed since the activation Initially, you will be able to use the automatic process once again what is the format of a hard drive? Two things are recorded discs: the number of disk drives itself and the volume serial number (VSN) of the partition on it. Tip # 1: The VSN is part of the data contained in the first sector of the partition, the format is changed unit. It is interesting to obtain the volume ID freeware utility to restore the original VSN. Before formatting, vol run a command prompt, note the VSN (for example, 1F2E-3C4B) in the second line. Then after that the format and the new Windows XP installation, defer the new activation until you run ID volume to restore the old VSN, and rebooted. Not essential - but keeps a "yes vote" against any significant change to come. (If you do not want to run this utility, the best way to achieve the same result would be to remove the old file Win XP HDD before reinstalling, rather than to reformat, but good.) Tip # 2: Another thing that changes the VSN is converting a FAT32 partition to NTFS. So, if you upgrade a system with FAT 32 to Windows XP and intend to convert to NTFS, perform the conversion before activating the system. Know that you can wait a bit: you have 30 days before having to activate it. Hardware machine when the first activation is what counts. Or, if you've activated, the volume of use of identification as described in Tip # 1. If you do this after activation, also the first copy of Wpa.dbl up files Wpa.bak, as described on Track No. 3 below, and, after completion of the conversion to restore these files and start again. TIP # 3: It is very useful to save the two files Wpa.dbl Wpa.bak of the Windows folder.Then System32 must be damaged, or if you do an "resettlement repair "of Windows XP, these files can be copied to restore the previous activation status. However, this only works in those limited circumstances. The contents of both files is adapted to the specific configuration of Windows, therefore, contrary to what many journalists and members of the community have written in recent months, restoring these files will not restore the activation status following a reformat and clean installation. The disk drive and partition recorded are those that the system has found first by the initial activation: normally the system began. So, if you change the record and return to install Windows on a new partition, which has lost two votes Yes In contrast, if you add a new hard drive, a copy of the original partition on it with an imaging program, and maintain the original hard drive as a secondary data disk, still recovering from a subsequent audit. This is because searches for all disks, and the vote will positive in both categories if it finds that the original, with the partition unreformed. If you change the hard drive, yes, you can reinstall the operating system.
