Is true or false Change 2 bytes to turn WinXPHome into Pro

A German computer magazine "CT" recently revealed a way to change the windows xp Home version to Pro version, just change the two bytes of the installation file. We can't guarantee the validity of this method, but introduce it to everyone, maybe the eye can point out its principles and flaws.

First of all, you can't modify the installed Windows operating system, but only on the installation CD (or the recovery CD provided by the PC manufacturer)

Specific steps:

1. Copy the Windows XP installation CD root directory and the i386 directory to your hard drive.

2. First take WindowsXP installation boot sector program (BootSector) CD change in

3. i386 \\ Setupreg.hiv of two bytes:

a. Open Registry Editor

b.Highlight HKEY_LOCAL_MACHINE

c.Menu: File -> Load Structure -> i386\\Setupreg.hiv

d.Assign an arbitrary Name to the imported structure eg "Homekey"

e. Enter HKEY_LOCAL_MACHINE\\Homekey\\ControlSet001\\Services\\setupdd

f. Edit the binary "Default" and change "01" to "00" Then change "02 to 00"

g.Highlight "Homekey" and select menu: File -> unload structure

4. Burn your new XP Pro installation CD

5. system installed WindowsXP Pro, Home of the serial number is still valid

Note: you can not install windows xp Pro SP2 in such a system is installed, you can only use the integrated SP2 installation disk.

Chinese and German version of XP directory may differ.
