So how can I use the genuine windows xp Pro Sp2, can not enjoy a penny (except electricity and network fees) can enjoy the benefits of genuine users?

The method is not too “ Complex"!! There are about 20 steps.

1, download the original Xp's iso disc image, the size is 505MB (all sizes do not match!)

2, download & ldquo; windows xp Sp2 patch & rdquo;. The size is about 285.83MB

3, download & ldquo; Windows 4 in 1 counting device & rdquo;. This is a very useful serial number generator. After running, select “windows xp Pro.”, click “Generate” to calculate the number. The speed is very fast! After the number is copied, the serial number is copied. It is recommended to count 2~3 as a backup! (You can download it in the attachment of this post!) Please download it to a directory, such as D:\\sp2.

4. Download “Windows Online Activation Program 1.0”. This is the tool to activate Sp2, very important. After downloading, unzip it into a directory, such as D:\\sp2.

5, use Winrar to extract the original Xp's iso CD image (that is, 505MB) to a directory (such as decompression to D:\\xp). (What? Without Winrar…… Halo, you can turn off this page, it is estimated that you don't understand ……)

6. Click “Start”-“Run&rdquo ; (assuming you just downloaded the "XP Sp2 patch" in D:\\, the file name is WindowsXP-KB835935-SP2-CHS.exe, just the original Xp's iso disc image is decompressed in D:\\xp) Input: D:\\WindowsXP-KB835935-SP2-CHS.exe -s:D:\\xp. At this point, the program will run automatically and be integrated into D:\\xp. There will be a prompt when you are done. At this point sp2 integration is complete.

7. Make a dos boot disk (please refer to the relevant information for details) or directly run setup.exe under D:\\xp. Remember to enter the xp serial number you just calculated.

8, long waits … … remember to back up the My documents, favorites and other files before installation, of course, there is a better way to select "upgrade" when installing under windows "upgrade" . However, if your xp version is newer than the one you just integrated, it will not work ……

9. After the xp installation is complete, restart, agree to the agreement and ask whether to enable automatic update, select “ Automatically update ”, then enter the user and other information, and skip “Windos registration & rdquo;. At this point you need to activate, ignore it, select “ then activate ”. Then you can enter the system.

10, it is recommended to restart first, after the restart may prompt to activate, you can choose "and then activate" /or simply turn it off. Remember to never change the system time.

It is best to install various system drivers at this time, especially the network card driver (because you need to activate Windows on the Internet later)

11, you can now perform the activation operation. Open D:\\sp2 (that is, you unzip the "Windows Online Activation Program 1.0"), after running the program, click on the Windows image in the window, then there will be a file written to C:\\windows\\system32\\ and pop up & ldquo; system file protection tips & rdquo;, ignore them.

12. After a while, a Windows activation program with a key pattern as an icon will appear. Select "Activate via the Internet" and make sure the Internet is connected at this time.
