Microsoft once assessed license fees based on the number of computers an OEM sold, regardless of whether a Windows license was included. Installing an operating system other than MS-DOS would effectively require double payment of operating system royalties. Also, Microsoft penalized OEMs that installed alternative operating systems by making their license terms less favorable. Some smaller OEMs and larger retail chains such as System76 have taken to specializing in Linux-based systems to their advantage from major suppliers' paucity of non-Windows offerings. While Microsoft claims the OEMs would be free to decide which keys to include and how to manage them,  competing OS vendors' relative lack of influence on the desktop OS market compared to Microsoft might mean that, even if signed versions of their operating systems were available, they might face difficulties getting hardware vendors to include their keys, especially if end users won't be able to manage those keys themselves. If you do not accept and comply with these terms, you may not use the software or its features. You may contact the device manufacturer or installer, or your retailer if you purchased the software directly, to determine its return policy and return the software or device for a refund or credit under that policy. You must comply with that policy, which might require you to return the software with the entire device on which the software is installed for a refund or credit, if any. Flynn of The New York Times characterized the license refund argument as using a loophole in the license agreement. Some OEMs have programs that specifically allow a user to receive a refund for an unused Windows license.
