The U.S. government and Microsoft reveal Chinese hackers broke in to online email systems and stole some unclassified data.

British regulators blocked Microsoft's purchase, thwarting the biggest tech deal in history over worries that it would stifle competition in the fast-growing cloud gaming market.

Microsoft says it rolled back a network change that may have caused thousands to lose access to its apps Wednesday morning. Key workplace engines like Teams, Outlook and Sharepoint were impacted.

Amazon, Salesforce and Goldman Sachs have also announced cuts during a brutal January for corporate workers.

Amazon began layoffs, reportedly affecting as many as 10,000 employees. That follows job cuts at Meta, Twitter, and Stripe, with CEOs citing economic uncertainty and a slowdown in online ad buying.

Microsoft is officially pulling the plug on perhaps the most-hated web browser that once dominated the competition. Internet Explorer will be put to rest in the summer of 2022.

Microsoft wants to acquire Activision-Blizzard for almost $70 billion. Microsoft says it won't harm consumers. But is the mega-merger a new kind of monopoly?

Activision Blizzard is behind huge games such as Call of Duty, World of Warcraft, and Candy Crush. But the company has faced reports of a workplace culture rife with sexual harassment.

According to Microsoft, the group is targeting technology companies that resell and provide cloud services and has been using phishing and password spray to gain entry to targeted networks.

China broke into tens of thousands of email accounts in January. Now officials fear the breach wasn't just about spying. It was to build the next generation of artificial intelligence.
