Although Microsoft no longer supports Windows XP updates, I'm sure many users still use it due to personal habits or job demands. Therefore, XP's product keys may still be necessary. Here lies the most comprehensive list of Windows XP product keys.

The following CD keys are official and original from Microsoft, primarily used for Windows XP Professional Service Pack 2/3 VOL/VLK system images, which are among the easiest to find on the Internet.

What's VOL and VLK?

VOLs (short for Volume Licensing for Organisations, also known as VL) are Windows OS setup CDs/DVDs or image files that contain the "VOL" acronym, indicating they are licensed copies of Windows. According to the regulations of VOL plans, VOL-licensed products don't need prior activation.

VLK (short for Volume Licensing Key) refers to the product key required in the VOL edition's deployment rather than the edition name. These keys are only suitable for VOL editions and serve one purpose: to prove the product is legal and licensed under VOL.

According to the license agreement, the product keys for the retail editions of XP can be used on only one PC; however, the ones for VOL editions can be supplied for any number of PCs. Second, retail editions of XP require activation, while VOL editions don't. Lastly, VOL editions of XP don't have a Home Edition, and their function is identical to that of a Professional Edition.
