"In the ensuing 11 months from January until now, we realized we had to move a little beyond the 5,000, so that put us at about 5,800," company spokesman Lou Gellos said, IDG News Service reported Wednesday.
The new round of cuts would occur in the United States and abroad, the company said.
Gellos said Microsoft did not anticipate any more layoffs.
The announcement was made soon after Microsoft's third quarter report showed a 14 percent drop in revenue.
