Really nice sonic, thanks

I'll study code, but it appears to work great.

sonic,

The XPKeyChanger works perfectly here. Very nice job, congrats.

Keep up the great work

Thanx for testing.

DisableEdits function was buggy. Updated the original.

Howdy sonic,

The application works fine here (well, at least the part that decodes and displays the key - haven't actually changed it...).



1) Regarding Windows XP activation code verification algorithm:

This comment is not to report a bug, or a request for a feature - It just adds to the pile of information for anyone interested on the subject...

Unless i'm wrong, (and i usually am ), the script merely reports failure of Windows to accept the provided key. One way, or another, it does the job though...

This document, more-or-less describes how the XP key can be validated (among others)...

MSKey Readme

... and this document (including references) helps someone understand what's discussed in the previous document:

Elliptic Curve Cryptography, Wikipedia



2) Regarding the way the scripts get to be executed & deleted upon completion:

There must be a more elegant way to execute vb scripts & wait for them to finish.
See if some of the code in this thread can be adjusted to your needs...

As always, good job - thanks for releasing the application with source!
