Microsoft has been reprimanded by the Advertising Standards Authority (ASA) in the UK over misleading advertising.
The UK watchdog upheld complaints about a magazine advert which claimed that the open-source operating system Linux was more expensive than Windows.
Referring to research, it read: "Linux was found to be over 10 times more expensive than Windows Server 2003".
The ASA concluded that the comparison was misleading because the operating systems ran on different hardware.
