To qualify for an additional license, you must already have a current, valid license for the same version of Windows XP — either the full version or the version upgrade. For example, you can qualify for a Windows XP Professional full version additional license if you already have a full version of Windows XP Professional. If you currently have a version upgrade, you're eligible for an additional license for the version upgrade only. To verify that you have a qualifying version of Windows XP, we ask you to simply enter the Product ID number (PID).
Notes
- You do not qualify for an additional license if your version of Windows XP was pre-loaded on your computer when you purchased it from a retailer. However, you can still order an additional copy of Windows XP. To do so, simply close this window and return to the Product Information Center.
- You may purchase up to three additional licenses for each original Windows XP version for which you have a current, valid license; however, you may purchase just one additional license at a time.

A Windows XP additional license Product Key is an electronic number that "unlocks" Windows XP and allows it to run. Your order of a new Product Key ensures security for all Windows XP customers by preventing the re-use of Product Keys by unauthorized users. Additionally, this method of software license distribution helps prevent piracy by keeping people who have not legally obtained a valid, single-use Product Key from installing Windows XP on their computers.
