Used PCs Sought for Windows XP
Buyers need to be especially wary when buying XP-based used PCs off sites like Craigslist.org and eBay, Kaplan said. Many used PCs purchased from those Web sites contain illegal versions of XP, and it is imperative to quickly check out the authenticity of Windows prior to or quickly after purchase.
The COA can be found in many areas like on Windows CDs and on or inside the hardware. Windows XP can also be validated on Microsoft's Web site.
According to Gartner, used or secondary PCs are systems that have been used for more than three months "and then passed on to a secondary fate."
