Application to convert Windows 'Product Key' into 'Product ID'.

Hi application experts, I have been searching for an application to convert Windows Product Key into Product ID.

(Product ID is the string of text / numbers listed under General tab of in the System Properties window, just below user and company's names)

I know for the fact that the application(s) does exist, but I just have no recollection of its name, author and where to find it.

Hi Steve, does it convert between Product ID / Key? Or does it just allow me to find and change product key?
Hi DCreature.  It converts the product ID back into the CD key, and gives you the option to change the product ID (presumably recalculating from the CD key you enter in the dialog).  I havn't tried it, but give it a whirl!

sda100, mmmmmm sorry but it only deals with Product 'KEY' :-(

What I want to do is like this:

1 Launch whatever app it is
2 Enter any Windows XP (Or other version of Windows) Product Key in a field
3 Click a button
4 The app displays Product 'ID'

Thats all I need :-)

Here is the reveal of the encryption algorithm:

scrathcyboy, mate thanks for the links. But once again I believe you didn't completely read my post and subsequent posts, just like some other threads of mine that you replied.

(Sorry I am not in the best mode today)

And it's getting very frustrating when I read a number of responses where people just quickly, really quickly, skimmed through posts without even trying to understand it first and post something from slighty relevant to complete irrelevant.

As a side note, Windows Product Activation (WPA) does not provide Product ID, it provides Installation ID, at least that's what I believe.

I need:
Product Key ---> Product ID.

and not this one below as Key Finder, Magically Jelly Bean, PraduKey, etc can already do that for me:
Product ID ---> Product Key.

Hello DCreature...

You can locate the Product ID in the registry,,,
Click Start ---> Regedit --

The value is a REG_SZ called ProductId and is held in the following

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Registration\


HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\

There will also be instances of the value within a couple of keys within the following sub-hive


Another Way ON OEM Installations of WinXP, the Product Key is stored (as Plain Text) in a File called oobeinfo.ini in the oobe Folder in the System32 Folder in the windoze folder. (OOBE stands for "Out of Box Experience", which is the thing that Runs when you first Boot up after Installing WinXP...

Hope This will help.

By the way, have u tried xpdec as suggested by me?

ppfoong, sorry mate, you're the one :-) !!!

Exactly what I need, but one thing though, the software claims that it does this for RC1 of Windows XP. I believe that quite old?

Do you happened to know same software but newer version or other software thats better to do exactly this? I must say I love the software, but it does half the job.

If you've got new one I'll grant you grade A :-) too!

ppfoong, if you also happened to know how to identify whether a copy of Windows XP is Corporate, OEM, or Retail based on contents of a CD or contents of the files on the CD please let me know, so I can start a new post to give you points :-)
DCreature said: if you also happened to know how to identify whether a copy of Windows XP is Corporate, OEM, or Retail based on contents of a CD

Heres the details to know if it is OEM version or retail...


WinXP's setupp.ini controls how the CD acts. IE is it an OEM version or retail? First, find your setupp.ini file in the i386 directory on your WinXP CD. Open it up, it'll look something like this:


The Pid value is what we're interested in. What's there now looks like a standard default. There are special numbers that determine if it's a retail, oem, or volume license edition. First, we break down that number into two parts. The first five digits determines how the CD will behave, ie is it a retail cd that lets you clean install or upgrade, or an oem cd that only lets you perform a clean install? The last three digits determines what CD key it will accept. You are able to mix and match these values. For example you could make a WinXP cd that acted like a retail cd, yet accepted OEM keys.

Now, for the actual values. Remember the first and last values are interchangable, but usually you'd keep them as a pair:

Retail = 51882335
Volume License = 51883 270
OEM = 82503 OEM

So if you wanted a retail CD that took retail keys, the last line of your setupp.ini file would read:


And if you wanted a retail CD that took OEM keys, you'd use:


Note that this does NOT get rid of WinXP's activation. Changing the Pid to a Volume License will not bypass activation. You must have a volume license (corporate) key to do so.
