Windows XP Home to Windows XP Pro

Change to Windows XP pro from Windows XP home

I can't really go with this hack because I am too lazy to do it secondly I don't  want to violate any copyrights or anything like that. One of my friends explains as how to turn windows xp home install disc to a windows xp pro disc.

It seems pretty simple because it just involves some registry changes.As you can’t install SP2 so you need to modify the changes in the install disc( if that's possible).
Alternately, buy XP Pro, or get a Mac.

As you can't change the installed windows but your installation CD.

Here is the whole trick step by step..
 
    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
    “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 such a WindowsXP Pro, so step 1.b)
    might be to integrate SP2 in your Installation CD

This will turn the windows xp home to windows xp pro. However what I suggest is to directly download the windows xp pro copy from microsoft rather than doing such drastic changes and doing burning all that.

Still if you are a computer geek and want to try this go ahead as these things are really interesting to do.
