Microsoft began its restructuring last year with 18,000 layoffs and, on Wednesday, announced another huge round of layoffs that will affect 7,800 positions within the company.

"We are moving from a strategy to grow a standalone phone business to a strategy to grow and create a vibrant Windows ecosystem including our first-party device family," Microsoft CEO Satya Nadella said. "In the near-term, we'll run a more effective and focused phone portfolio while retaining capability for long-term reinvention in mobility."

Last year's layoffs occurred as Microsoft worked to eliminate redundant roles or roles that were no longer needed after it acquired Nokia's devices and services division, and Wednesday's move will continue that push, affecting employees mostly in the mobile hardware business. Microsoft said the layoffs should be complete by the end of this year.

The news follows on the heels of Microsoft's executive shakeup last month, during which we learned that former Nokia CEO Stephen Elop and three other high-level executives were leaving the firm.
