Office 2007 Ultimate Key Windows, MAC easily modif

Now we are all ADSL Internet access, network time-consuming when you check you will find, every time the Internet telecommunications network card will record your MAC address, because IP address is dynamic (each time the Internet is different), but MAC address is ─ ─ constant unique for each NIC has a MAC (physical) address, so MAC address has become an online customer ID card, by recording the MAC address, you can be sure the network!
A, MAC address, use

MAC address is fixed in the card, each card's MAC address is different. NIC in the production process, manufacturers will burn in its EPROM inside a set of numbers on this set of numbers, each card is different, this is the card's MAC (physical) address.
the uniqueness of the MAC address, so it is mainly used to identify the network user's identity. For example, when the ADSL Internet access, telecommunications billing with it, make sure you on the network; in the campus network, MAC addresses can also be used to identify users. For the official campus network users, their MAC addresses registered in the server side,Windows 7 Home Basic, if you are illegal users, the server was not found in your network card MAC address, so that when you try to connect to the Internet, the server will be immediately recognized you,Office 2007 Ultimate Key, stop you connected to the network.
Second, MAC addresses can be modified

some occasions, for example, the user posing as a formal network, you need to modify your network card MAC. To modify the MAC address, you can achieve by way of hardware, namely the use of cards provided by the manufacturer to modify procedures to burn card EEPROM, that while feasible, but risky, operation is also complicated, even if you are experienced, it is inevitable error in the operation.
In fact, you totally do not need to use programming methods, to modify the MAC address of network card. To know when the Windows installation will be automatically read from the card into the MAC address,Office Professional Plus 2010 Key, store it in the registry for later use. When the data transmission network, data packets sent from the card requires a source in the MAC address, the MAC address is read from the registry (not read from the card), so if you modify the registry The MAC address of the NIC EEPROM is equivalent to change the MAC address of the actual effect is the same between the two!

three ways to modify the registry in the MAC

1 , the use of software changes

This method is applicable to all types of card. In different Windows, use different software to modify MAC.
(1) Win2003/XP/2000

If your system is Win2003/XP/2000, you can use the SMAC (download address

The software has two kinds of operation mode, if you enable title bar to see the current operating mode.

use of the software is very simple to run and click input box, enter the MAC address you specified (Figure 1), then click the right side of the > Figure 1

Note, trial version can not enter a new MAC address, MAC can only change the 0C-0C-0C-0C-0C-01

(2) Win98
If your system is Win98, recommend the use of properties and make it



If your card uses the RealTek RTL8139 chip company, you can modify the network card properties MAC, MAC address that will be in the registry with changes as follows:

in Win2003/XP/2000,Office Pro Plus 2010, click menu network adapter below, enter your MAC address to specify the value (for example), attention to continuous input of 12 digits or letters (do not enter the middle -); restart the computer after the change to take effect. As for the MAC under Win98 modification method, the above method is similar.

Figure 2

If modifications, in Win2003/XP/2000, you and wants to restore the registry in the MAC address into the intact , you can choose

for non-RTL8139 chip card, you can directly modify the registry of the MAC, Note: Modify the registry before, first back up the registry.

(1) Win2003/XP / 2000

Click the 0002 and so the primary key,Microsoft Office 2010 Product Key, look for the content of DriverDesc to understand which card to use the primary key (eg 0001) if params entry under the primary key, the primary key is also used by the NIC;
