Ars Technica: Linux users have always vocally encouraged major hardware vendors to unbundle the Windows operating system or offer Linux preinstallation. Although several prominent vendors are beginning to embrace this concept, they only support it on a limited subset of their hardware offerings. This means that Linux users often pay for a Windows license that they never use, and it also means that Linux users are forever attempting to recoup the "Windows tax."
The cost of the Windows license bundled with OEM computers has long been a source of ire for Linux enthusiasts who erase unused Windows installations. The controversy surrounding the so-called Windows tax flared up again this week following a report that Lenovo has agreed to reimburse a buyer for an unused Windows preinstallation license, but only if the individual would sign a nondisclosure agreement.
