Here’s the detailed breakdown you asked for.
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
b) Highlight HKEY_LOCAL_MACHINE
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
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 such a WindowsXP Pro, so step 1.b)
might be to integrate SP2 in your Installation CD

Hmm thanks, but i thought microsoft brought out an official way to do it, home is already installed and do not want to have to reinstall it, otherwise i would just put prof on. Someone told me that microsoft had an official mod for this

You could always get an upgrade disc.

Ok guys, I do own XP Prof leagle copy and also XP Home which came installed on the laptop. I want to be able to upgrade the XP home on the laptop to Prof without reinstalling the whole OS, acording to a Microsoft accredited tutour this is possible and allowed by Microsoft.

I vaguely remember hearing something about how to do this.. but upon searching I came up blank.. other than the suggestion dealing with the HOME CD...

Not doubting the legallity of your copy. But they do make an upgrade version. Also unless I am mistaken you can put the Pro cd in, it will see a "lower" version and ask if you want to perform an upgrade.
Obviously have all important data backed up first...
