Microsoft confirmed today that a security update for its Excel spreadsheet had turned English text in an important Windows tool into Chinese.

The admission was the second in the past two days from Microsoft's Office team of a gaffe involving a recent security update.

Friday's announcement involved the seven-patch update Microsoft shipped on Tuesday for Excel. "We have received reports from some of our Excel 2003 and Excel 2002 customers that after installing update KB978471 or KB978474, they are seeing non-English text in the 'Add or Remove Programs' tool (Win[dows] XP) or the 'Programs and Features' --> 'Installed Updates' view (Vista, Win[dows] 7)," Microsoft said in an entry published early today on the "Office Sustained Engineering" blog.
