How do you verify windows xp product key is valid without installing?
If your box looks like here http://www.microsoft.com/oem/sblicense/default.mspx then you have bought an OEM version of Windows XP. OEM stands for Original Equipment Manufacturer, and most often refers to the likes of Dell or Gateway. At least originally, “OEM versions” of products were usually the same products that you’d find at retail, but with no-frills packaging, reduced support, and sometimes lesser warranties. As a general rule, OEM software is usually much cheaper than full retail copies, but only slightly cheaper than retail upgrades. Vista upgrade pricing, plus a word or three on the limitations of the upgrade versions If your package is just an envelope with a CD then your copy of Windows XP is illegal as it supposed to be distributed with a new PC only as a recovery CD for already installed operating system.
