Does anyone know of any program that allows me to change my product key from volume license to OEM? I lost my recovery cd's and have used a disk that had corporate licensing. I tried to change the key using the activation utility that is pre-installed on XP, but to no avail. The keys are obviously different during the installation of XP, so I had to use the volume license key to install it and get the updates. Any help would be appreciated. Thanks guys.

Short answer: the installer "channel" must match the key you try to use. Because you installed from corporate/volume media, an OEM key will generally be rejected — that is the root of the "Wrong key" message. Microsoft documents that the media/channel (retail, OEM, volume) and the product key must match; attempting to swap channels without the matching media often fails.
How to change the Volume Licensing product key (Microsoft).

Practical options and safe steps:

  • If you want a guaranteed fix, reinstall using the correct OEM/recovery media that matches your COA/OEM key. If you lost the recovery CDs, request recovery media from the PC maker or use an OEM install disc for the same SKU. Back up data first.
  • If you want to try without reinstalling, the supported Volume Licensing method uses the Activation Wizard (you must back up the registry first). The key parts are editing the OOBETimer value and running the activation UI, then selecting Change product key. For example:
Edit HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\WPAEvents\OOBETimer
then run: %systemroot%\system32\oobe\msoobe.exe /a

Those steps are described in the Microsoft article above; note Microsoft says the scripted/Activation-Wizard method is intended for volume-license scenarios and will not convert media/channel types.

About the program suggestions already posted by others: pointed to Microsoft's Product Key Update utility — that tool can sometimes replace a non-matching key (COA) without a full reinstall, but it is not guaranteed to work for every XP edition or image. It is worth trying before a reinstall, but if it fails the supported path is to use matching OEM media or do a repair/clean install. For completeness, is correct that retail CDs are often usable for reinstalling OEM machines, but the product key and media channel still must match for activation to succeed.

If you need step-by-step help for any of the above (running the Activation Wizard, getting recovery media, or using the Product Key Update pathway), include the exact XP edition and whether you have a COA sticker — that determines which route will work.

I have already tried that and it did not work. The error response was something like this, "Wrong key or maybe mistyped". I do know that I did not mistype it. I know there is a difference between OEM keys and Retail (volume license) keys. I think that because I installed a retail version, I have to use a retail key and that means that I can only replace that key using the above method with another retail key. I am still unable to change out the key with the OEM key on the computer. Thanks for the advice, though.
