the question is not clear. \nyou had an old copy of xp - WHERE. on a CD or PC?\n\nif it was on a CD - then it has no registry.\nif it was on another PC - then startup up that PC, click start->RUN->type"regedit" and search the registry for the KEY.\nif it was on this new PC (on which you installed XP again) - then the old registry is gone, as it was re-written by the new one.\n\nyou bought a new pc and installed XP - SO WHERE WAS THE OLD XP?

Customer Support\n(800) 252-5722\n\nYou can call that number and ask them to send you a copy of the installation CD.\n\nOtherwise you can find somebody that's selling it on an auction and ask them to send you the driver files.  Worked for me =)

Assuming your copy is registered/you have a liscence you could contact microsoft about a replacement disc. As long as you can prove that it is a legitimate version on your computer that has been paid for.\n\nEither that or contact whoever sold you built the computer and ask for the disc

Was it installed on your PC when you got it?  Sometime people put the sticker with the product key on the case itself.  You could also get in touch with Microsoft to see if they can help.

Here's your fix, only if your running XP and you have an OEM CD.\n\n1. Boot up with the WinXP CD and at the Setup Screen press the Enter Key.\n  \n2. You will be taken to the Windows XP Licensing Agreement. Press F8 to proceed.\n\n3. The next screen gives you the option to do a fresh (clean) install or to repair\n     the selected Windows XP installation. To run a Repair Install press "R".\n\n***CAUTION*** if you do not see the option to repair the selected Windows XP\ninstallation DO NOT choose the option to continue installing a fresh copy without\nrepairing as that will overwrite your data and cause unrecoverable data loss.\n\n4. If you originally installed XP with Service Pack 1 and later installed Service Pack     2,  you will need to re-install Service Pack 2.\n\n5. If you have any Microsoft Office products installed,  you will need to re-activate\n    with the Product Key code. Contacting Microsoft may be required.

I had a copy of Windows XP that had a key number that wouldn't be accepted, so I had to phone Microsoft to get a new number.\n\nI don't know if this is possible with Microsoft Office, but if it is, it shouldn't cost you anything. The call should be toll free too.\n\nI'm not sure if this will work, but look in tools/manage add ons to see if there is an active x control that is creating the product key message.\n\nIf you have a copy of Windows XP that you want to update from Microsoft's site, sometimes you get a message saying the product key isn't valid, so you can't download security updates. This is due to an activex control that can be disabled. It is perfectly legal btw to disable this activex control, whether or not your product key is valid.

Ring Microsoft.  They are very helpful.  You still need the product code which is either a sticker on your computer or on a box you bought Windows XP on.  You don't need to register with Microsoft but you do need to Activate the operating system after a reinstall or repair.  If you think you have a dodgy copy of Windows, go out and buy a student version which will be fairly cheap and use that product code.  It must be the same type ether home or professional.\n\nNote: It really isn't worth cracking or using a pirated version because every time you update the patches or have to do a reinstall you will meet this issue again.

If you hadn't formatted I could have been of more help, I have a program that gives you the serial of an installed version of Windows - but you say that the hdd is formatted. \n\nYour options are - obtain an illegal key, or contact microsoft. \n\nDidn't you stick your product code on the box of your pc though? You are required to have your product key sticker stuck to your pc, if you bought the pc without this you restle with the company that sold it to you.

if it is a retail copy of XP, try contacting microsoft support, but if it is an OEM version (ie. came with the PC) you probably will have to contact the computer manufacturer or reseller.
