To modify the SID for Windows 7

A unique sid (Security ID) is created when the Windows system is installed, and it is used to recognize every host, and if there are two hosts with the same SID on the same area network, a warning message will appear. In general, it is not possible to reproduce the SID at each installation, but if you use TrueImage or ghost to prepare the system directly and install it to another computer, or a virtual machine that uses a virtual machine such as VMware, such as the clone feature, it will generate a duplicate SID problem.

Early common NewSID to produce a new SID, and renamed the name of the host, but if you use it to update the SID of Windows 7, will not be able to open the situation, there are many people on the Internet to help! So to change the SDI is still a good use of Sysprep.exe most insurance, but ... The most painful question comes in: You have to re-enter the gold keys and activate Windows 7! Its usage is as follows:

1. After opening the C:\Windows\System32\sysprep folder, perform the Sysprep.exe

2. In the System Readiness Tool dialog box, remember to tick [generalize] to generate a new SID, then press the [OK] button

3. After a period of waiting, it will be re-opened and entered into the setting screen, after which the user account, the name of the machine and the gold keys are entered into the conversation block, and the input is entered into the system, so long as you re-activate Windows 7, you're done!
