An anti-piracy tactic by Microsoft Corp. that turns some computer users' screens black has set off a wave of indignation among Chinese consumers, posing renewed problems for the software maker in the huge China market.
In the week since Microsoft deployed an updated anti-piracy tool here, some Chinese have fumed about what they see as an invasion of privacy. Users of legitimate software have been turning their own screens black in protest. One authorized user complained to the police.
Windows Genuine Advantage has been in use worldwide for several years. The update that started to affect Chinese PC users last week did exactly what it was intended to do: get people's attention.
