XP Professional X64 This is new, unused with valid key/activation code. I purchased a quantity of these 'promotional' packaged disks for a computer network I built for a friend. Ended up with a couple extra. Selling ONE @ $85.00 USD shipped and insured via USPS First Class INSURED. If you want faster ship (Pri Mail, etc) I will do that at additional cost. Again, this is one unused promo copy (FULL VERSION, not upgrade) of Windows XP Professional 64-bit version.. This is NOT an OEM or retail package. It is a Genuine Hologram CD in a sleeve with valid activation key. Payment by USPS MO, Check or the dreaded PayPal (+$0.50) Also will take eqiuv value in gold or silver (bullion/ coin) TRADES considered: RRA, LMT, Colt AR-15 lower receiver (stripped or complete) Rem/Win/other SHORT ACTION (reciever & bolt), or complete gun in rough shape if action is good for a project.
