FREE Upgrade Windows XP Home to Windows XP Pro

 

Using Microsoft Windows XP HOME edition? Want to upgrade to PRO edition but do NOT want to spend any cent? Here is a trick for you to upgrade for FREE!

Note: Microsoft may not like the idea and it may void your Microsoft Windows license. I do not responsible to anything.

yes indeed, you can’t change an installed Windows but only your Installation CD (or even a recovery CD in case the manufacturer had not left out important parts)

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 :
    1. Open Regedit
    2. Highlight HKEY_LOCAL_MACHINE
    3. Menu: File -> Load Structure -> i386\Setupreg.hiv
    4. Assign an arbitrary name to the imported structure e.g. “Homekey”
    5. Goto HKEY_LOCAL_MACHINE\Homekey\ControlSet001\Services\setupdd
    6. edit the binary key “default” and change “01” to “00” and “02” to “00”
    7. 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

Please check the menu-entries as I don’t owe an English copy of XP and have to guess them.

Thought:
Have you read it? It might work for Recovery CD! As we know, many notebooks come with Microsoft Windows XP Home edition and Recovery CDs. I checked Dell website, upgrade WinXP Home to WinXP Pro edition need to add extra RM266 (USD70). So… :twisted:

    but i think by doing so, you break the EULA contract, and this is equally illegal as getting a pirated copy of windows xp professional, which is easier to do so
