It has only been about a month, but Windows 10 is reaching even more users. Microsoft is reporting that 75 million devices now are running the brand new operating system, CNET reports.

In its first day, Windows 10 was installed on 14 million devices, Microsoft said. Two weeks after its launch, 12.6 percent of unique visitors to the ZDNet website came from computers or mobile devices running Windows 10.

Wednesday, Microsoft said that 75 million devices worldwide are using Windows 10. The 75 million figure is coming from Microsoft's corporate vice president of Windows and Devices Group, Yusuf Mehdi.

Windows 10 users are also starting to download more apps. Mehdi said that Windows 10 has seen six times as many app downloads from the Windows Store than Windows 8 has seen. Mehdi added that 90,000 unique PC and tablet models have upgraded to Windows 10.

Microsoft Windows 10 has been available as a free download to Windows 7, Windows 8, Windows 8.1 users and some business customers since July 29. For those that do not qualify for the free download, Windows 10 can be purchased for $119 or the pro version for $199.

Not everyone was able to download Windows 10 on July 29 as Microsoft elected to use a staggered release system. The first to try out Windows 10 were part of Microsoft's testing program called Windows Insider. After that, a reservations system was used to decide who would receive it next.

Windows 10 has been getting regular updates to fix various bugs encountered by users. So far, there have been four updates, but Microsoft is not revealing what is all included in the updates.

Microsoft has a lofty goal for Windows 10, it wants the operating system to be installed in 1 billion devices by 2018. This would include smartphones and Xbox One video game consoles.

Microsoft wants developers to know that Windows 10 is really catching on, Tech Crunch reports. Developers are encouraged to start creating Windows 10 apps and programs to catch onto this growing user base.
