VOLs (short for Volume Licensing for Organizations, a.k.a., VL) are any Windows OS setup CD/DVD or image files containg the "VOL" accronym, indicating that it is one of the licensed Windows copies. 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 with one effect–prove the product is legal and licensed under VOL.
According to the license agreement, the product keys for the retail editions of XP can only be used on one PC, but the ones for VOL editions can be supplied for any number of PCs for use. Second, retail edition of XP need activation, while VOL editions don't implement this concept. Last, VOL editions of XP don't have a Home Edition, and their function is exactly the same as a Professional Edition.
