If you now sit there and pout over having a sad Windows XP Home Edition, you can turn it into a Windows XP Professional if you prefer it.
I show you how to do a Windows XP Home Edition installation disk into a genuine Windows XP Pro by changing 2 bytes. You must use SP2 or SP3 for this to work.
This is How your Windows XP Home Edition is going to be a XP Professional:
1. Copy the main folder (root) and the folder "i386" of the Windows XP CD
to your hard drive
2. Extract the boot sector from the installation disk (CD)
3. Change 2 Bytes in i386 \ Setupreg.hiv:
1.Open Regedit:
2.Mark HKEY_LOCAL_MACHINE
3.Menu: File -> Load Structure -> i386 \ Setupreg.hiv
4.Make a random name to the imported structure e.g. "Homekey"
5.Go to HKEY_LOCAL_MACHINE \ Homekey \ ControlSet001 \ Services \ setupdd
6.Edit the binary key "default" and change "01" to "00" and "02" to
"00"
7.Mark "Homekey" and go to menu: File -> Unload structure
4. You can now burn out the new Windows XP Pro CD.
5. Install Now, Windows XP Pro, as usual, then your XP Home Key will work in the Pro version.
I take no responsibility for errors that would occur when using this method.
