XP Home to XP Pro hack -- anyone tried this?

Brian

From http://www.gizmodo.com/gadgets/software/howto-change-windows-xp-home-to-windows-xp-pro-105486.php :

"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 :
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

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

The Windows XP Home Edition with SP2 installation CD
consists of 556MB files. Windows XP Professional with
SP2 consists of 579MB of files. Making those hacks is
not going to make up for the 23MB of additional required files
required for XP Pro!

Also, it is an illegal to "reverse engineer" the Windows XP
operating system. Chances are it will not activate and may
cause the forfeiture/termination of your Windows XP license.

From the EULA:

4. LIMITATIONS ON REVERSE ENGINEERING,
DECOMPILATION, AND DISASSEMBLY.
You may not reverse engineer, decompile, or disassemble the
Software, except and only to the extent that such activity
is expressly permitted by applicable law notwithstanding
this limitation.

15. TERMINATION.
Without prejudice to any other rights, Microsoft may
terminate this EULA if you fail to comply with the terms
and conditions of this EULA. In such event, you must
destroy all copies of the Software and all of its
component parts.

Ignore Carey Frisch, he isn't a real MPV. He even misspelled it as "MVP" !
Furthermore, he also poasted your original poast in his sig, which makes him
even more suspicious. I personally think he is a troll.

As an answer to your question: Yes, it will work. Don't forget to download
and install Service Pak 2 after the hack.

HTH and HAND.

Frank is the only *real* MPV in this group, unlike you. Frank also has
great knowledge of Windows XP and is a valuable support engineer, providing
lots of help here. Just what are your contributions to the group?

You're right, it's not going to make it XP Pro. I suspect it wuld result
in a cosmetic change only.

Offline editing of registry keys, extracting/copying files and burning a
CD do not really constitute reverse-engineering, decompilation or
disassembly of the software.

Actually, modifying a few bytes is not reverse-engineering, decompiling,
or disassembling the software in any way. It's just editing existing
code. The EULA should specifically state that editing is forbidden,
but it doesn't... :)

Correct. They don't constitute it at all.

Quite likely, since the official Microsoft designation is MVP ...

It can't, otherwise you'd be forbidden to edit the registry at all and
3rd party software would be unable to be installed or removed.

This article seems to suggest that there are more steps required, than that
simple registry change.
The original article being 8 pages long.

One wouldn't mind so much if there were some unique and appropriate
value to XP Home, such as a total destruction of the ability to
manipulate the OS via network and Internet.

Interesting...
Barring the implications with the EULA, etc - very interesting.
Almost interesting enough to test, just to see.

Come on people, you know your curiosity is tweaked as well... Don't lie.
The subject of this post is misleading, however. The actual claim is:

Free Upgrade From XP Home to XP Pro Lite
-------------------------------------------------------
'... many of the features of Windows XP Pro, such as Remote Desktop and
user management, can be enabled in Windows XP Home simply by changing two
bytes in an installation data file ...'

So not XP Home to a full fledged XP Professional.
Somehow I doubt the changes dictated would enable even the simplest of XP
Professional functions - but I have been wrong before..
(That time I thought I was wrong.. But it turned out I was right.. So I was
wrong about being wrong. *grin* Yeah.. uh huh)

XP Home is still the best selling OS all the way around--if it ain't broke why change it?
