When I checked just now, a package specifically intended for refurbished PCs cost only $50 for a 64-bit copy. When I checked a few minutes ago, Amazon was offering OEM Windows 7 Professional packages from multiple sellers at prices ranging from $101 to $150.

The current price for OEM Windows 7 Professional at Newegg, for example, is $140. You can find OEM System Builder software from dozens of online merchants. However, the license agreement with those copies explicitly prohibits you from using that software on a PC you build or refurbish for your own personal use. Under Microsoft's arcane licensing rules, you can legitimately purchase OEM copies of Windows 7 (any edition). OEM Windows software for new or refurbished PCs I don't recommend taking a chance with random sellers on eBay or Craigslist-not when there are so many well-established merchants that offer proper warranties and return policies, as well as an assurance that the underlying Windows license is legitimate.

Used and refurbished PCs with Windows 7 preinstalled Big online retailers that serve business markets should have similar selections covering a wide range of brands and the full spectrum of prices.
