A year after announcing Windows 10 hitting its goal of running on one billion monthly active devices, Microsoft has today disclosed that its desktop operating system is currently running on 1.3 billion active devices. The announcement comes through the company's Q3 FY21 earnings call earlier today.

Earlier reports had suggested that the PC industry was seeing a surge as more people had to retreat indoors due to the COVID-19 pandemic. As more users bought new PCs for school and work from home needs, Windows 10 also managed to increase its market share.
