The Week Ending Aug. 25

Topping this week's roundup of those having a rough week is IT services giant Infosys, for the second week, which is undergoing a very public fight for control of the company's board of directors.

Also making the list this week are Microsoft for having to promise that it will stop downloading Windows updates without explicit user permission – in Germany, at least; Google for having to remove hundreds of applications from Google Play because of potential spyware problems; AT&T, whose bid to acquire media giant Time Warner for $85.4 billion may have hit a roadblock in Brazil; and Samsung heir and acting chairman Lee Jae-yong, who was sentenced to five years in prison Friday after being convicted on charges of bribery, perjury and embezzlement.

Not everyone in the IT industry was having a rough go of it this week. For a rundown of companies that made smart decisions, executed savvy strategic moves – or just had good luck – check out this week's 5 Companies That Came To Win roundup.
