Microsoft is laying off another 800 people, adding to the 5,000 the company has already let go this year.
The Techflash blog first reported the news.
The affected people are based around the world and work in various groups and will be notified on Wednesday, Microsoft said.
As is its usual policy, Microsoft will regularly monitor its size and make adjustments as needed, he said.
This marks the first large layoff in the company's history. It immediately let go about 1,400 people after the cuts were announced in January. It made an additional cut in May, saying that the round nearly completed the total 5,000 cuts.
At the time, Microsoft CEO Steve Ballmer said that more cuts could happen.
The most recent cuts follow an earnings report that included a 14 percent drop in revenue. Market reception to the news was generally positive, since the drop was less than expected.
