Hack to Change Windows XP Home to Windows XP Professional

Enable the features found in Windows XP Professional on your Windows XP Home Edition installation with this hack. It will allow you to turn your Windows XP Home CD into a Windows XP Professional CD.

Note: If your Windows XP CD does not contain Service Pack 2, you might want to Slipstream Your Windows XP CD first as you will not be able to upgrade an installation after using the CD.

1. Copy the root directory and the i386 directory of the WindowsXP CD to your hard drive.

2. Extract the Bootsector of your Windows XP CD. You can use BBIE to do this.

3. Click START–>RUN–>REGEDIT

4. Highlight HKEY_LOCAL_MACHINE

5. Click FILE–>LOAD HIVE and select the Setupreg.hiv file
This file is located in the i386 folder. Use the one you extracted to your hard drive from your Windows XP CD.

6. Locate the following registry key:

HKEY_LOCAL_MACHINE\Homekey\ControlSet001\Services\setupdd

7. Edit the DEFAULT key and change the following values:

01 to 00
02 to 00

8. Change the name to the value HOMEKEY to anything.

9. Locate the following registry key:

HKEY_LOCAL_MACHINE\Homekey\ControlSet001\Services\setupdd
Edit the DEFAULT key and change the following values:

01 to 00
02 to 00

10. Highlight HOMEKEY and select FILE–>UNLOAD HIVE

You can now burn the data on your hard drive to a CD to make a new Windows XP CD. Then use the CD to install Windows XP. Be sure to make the CD bootable. You can use the instructions here to help you do that.

    Yup,

    No doubt about it – SP3 picks up the inconsistency. It’s during product activation after the SP3 install. But you can’t activate in safe mode with no networking (Catch 22 !).
    Anyone cracked this yet ?

    Me,
    I had the same problem. I did this and when I downloaded service pack 3 I had the same problem. I don’t know how to get the original file back thats altered in this process though.

    I used this hack and it worked great. But when it installed SP# I could no longer log on. I had to un install SP3 in safe mode to use the PC again.

    Hmm why don’t you just download a copy of XP Pro student edition from TPB? Either way illegal deeds will be done, however my way is much simpler =P
