If a PC shipped with Windows preinstalled, can you remove the OS and install Linux instead? Well, no, according to Microsoft. A somewhat obscure Microsoft site aimed at helping schools deal with donated computers flatly states: "It is a legal requirement that pre-installed operating systems remain with a machine for the life of the machine."
According to a later Register story they have removed this requirment. Apparently what they really ment to say is that people donating machines should donate any OEM software. (Well except in sensible parts of the world, like Germany, where courts have ruled that a PC is simply a bundle of parts, with any OEM software being part of the bundle.) -- Mark Evans St. Peter's CofE High School Phone: +44 1392 204764 X109 Fax: +44 1392 204763
