Windows XP Hack

The German Computer magazine C'T (Heise) is describing in its current print issue how to change Windows XP Home to a Windows XP Professional version before install.

Microsoft is not going to like this. The C'T magazine apparently found out that by changing 2 bytes in the installation file of Windows XP Home, it will install a Windows Professional. Some functions are missing, but Remote Desktop and User management and enhanced security features are present.
The article is in the C'T 12/05 on page 148. The hack requires several steps. The major change is in a registry file setupreg.hiv in the i386 folder.
you can’t change an installed Windows but only your Installation CD (or recovery CD)
1. Copy the root directory and the i386 directory of the WindowsXP CD to your harddisk
2. Extract the Bootsector of your WindowsXP CD
3. Change 2 Bytes in i386\Setupreg.hiv :
a) Open Regedit
c) Menu: File -> Load Structure -> i386\Setupreg.hiv
d) Assign an arbitrary name to the imported structure e.g. “Homekey”
e) Goto HKEY_LOCAL_MACHINE\Homekey\ControlSet001\Services\setupdd
f) edit the binary key “default” and change “01” to “00” and “02” to “00”
g) Highlight “Homekey” and select menu: File -> unload structure
4. Burn your new XP Pro CD
5. Install WindowsXP as usual. Your XP Home Key will work.
Note: You cannot apply SP2 to the hacked WindowsXP Pro.
