Change XP Registration Key...


A customer have a computer with Wiondows XP Pro Tablet Edition installed on hes computer but the key isn't the legal one, and he wants to change it without having to re-install the OS.

How can I change the registration key?
How do I know for sure that he's key works on the already installed OS?
(already ocurred to me having XP keys that don't work on every XP installation CD).

Use this at your own risk, its free and it works, but I would recommend backing up before doing anything.

- To retrieve and change your XP Key
- To retrieve all Microsoft Products keys
- To save your XP activation file
- To retrieve your lost XP system passwords
- To retrieve your lost RAS (Remote Access Settings) passwords
- And to generate new passwords
This utility will enable you to change the product key:

Good luck!

Before I try any of those tools I must know somethig...
How do I make sure the customer key works on the already installed OS?
Because if it doesn't I may make the OS fail the start right?

Hi Alex,

Use the Keyfinder & Changer from

If you try and change the key and the new one is invalid it won't let you use it.

Having said that "ALWAYS" make sure you have crucial data backed up before you do anything like this. Although I have never had this fail personally and I have used it 100's of times.

Hope that helps

You're right FriarTuk, sorry.
I've been too busy to reply to my questions.

At least it worked!
