Windows XP Genuine Key Generator for Windows XP 32-bit
I tested it with the latest Microsoft Genuine Advantage Diagnostic Tool, and it gave me this;
Unable to upload image, you can see it in the download folder (ValidationStatus.bmp)
Reading the Validation status: Genuine

This key generator can generate retail or volume license keys. To generate a volume license key, select 'Windows XP Corp' from the settings drop down box and click 'generate'

To generate a retail key Select either 'Windows XP Pro' or Windows XP Home' from the settings drop down box.

Once you have generated your key you probably want to test it. To test it change your existing one with the MagicJellyBeanKeyFinder in download folder to the one recently generated. Once changed, run the MGADiag in download folder and check to see if the status says 'genuine'.
